So sit back, open your eyes wide and prepare to be dazzled by the bewitching beauty of opal!
What is opal?
Opal is a unique and stunning gemstone. It forms in special environments, often associated with sedimentary rocks. When small quantities of silica-laden water penetrate rock fissures and settle there, they eventually form opal over time. This natural process creates a stone that seems to capture the essence of the rainbow, with bursts of color that can vary depending on the angle from which you look at it.
Opal comes in a wide variety of colors, from white to black, with different shades of red, green, blue and even yellow. It is this richness of color that makes each piece of opal so unique and fascinating.
A brief history of opal in jewelry
- Ancient Egypt: Opal has a long history in jewelry, going back thousands of years. The ancient Egyptians believed that opal was a magic stone containing shards of all the other precious stones.
- In the Middle Ages, opal was considered a stone of luck and protection. It was believed to bring good luck and ward off misfortune to those who wore it. Charlemagne’s crown” was adorned with a magnificent opal called “Orphanus”.
- Napoleon and Josephine: Napoleon was also a fervent admirer of opals, and gave Empress Josephine an opal named “Incendie de Troie” for its fiery red fire. It is said to have weighed almost 700 carats and unfortunately disappeared in the course of history.
- During the Victorian period: opal became very popular in jewelry, not least because of Queen Victoria, who loved wearing opal jewelry.

- Art Nouveau: Opal was also very popular during Art Nouveau at the turn of the 20th century, for its organic appearance and unique play of colors.

- Today: opal continues to be a highly prized gemstone in modern jewelry, with jewellers all over the world using this magnificent stone to create unique and spectacular pieces.
- In the media: Opal is often seen on singer Taylor Swift, model and actress Cara Delevingne, actress Sarah Paulson, actress Emma Stone and Duchess of Cambridge Kate Middleton. She has also appeared in many legendary films such as Titanic and Pretty Woman.
Types of opal
- White opal: White opal is one of the most common and popular types of opal. It is characterized by its milky or white base, often with reflections of subtle color play (like a kind of firework inside the stone). These opals can come in a wide range of colors, from pastel hues to vivid hues.

- Black opal: Black opal is a rare and highly prized variety of opal. It is mainly mined in Australia and is famous for its deep black background, which sets off a bright, vibrant play of colors. Black opals are often considered among the most precious and sought-after.

- Fire opal: Fire opal, also known as Mexican opal, is distinguished by its play of warm, flamboyant colors, including shades of red, orange and yellow. It is generally translucent to transparent, and can appear incandescent when exposed to light.

- Hyalite opal: Hyalite opal, also known as “water opal” or “glass opal”, is a transparent to translucent variety of opal. It is distinguished by its purity and clarity, sometimes with gaseous inclusions that give it a milky appearance. It has no color scheme, but fluoresces strongly under UV light, making it a fluorescent green!


- Boulder opal: Boulder opal is a unique form of opal in which the entire opal is still attached to the rock on which it was formed. It is known for its natural patterns and vibrant colors contrasting with the rock matrix. Boulder opals often lend an organic, rustic look to their jewelry.

- Matrix opal: Matrix opal is a variety of boulder opal in which the rock is in the majority and shows fissures in which the opal has infiltrated. Matrix opal is therefore “in” the rock, while boulder opal is “on” the rock. It is distinguished by its unique patterns and inclusions, often visible on the surface of the stone. These opals offer an earthy, natural look, with variations in color play that can be fascinating.

- Precious opal: Precious opal includes all opals with a play of color. such as white and black precious opals, boulder and matrix opals, etc.
- Common opal: Unlike precious opal, common opal has no play of color. It looks somewhat like an agate and can come in many colors. It is generally very affordable, but fire opal is an exception in this category, being highly sought-after and more expensive.

Qualities to look for
Of course, the following applies if you’re looking for a “sought-after” opal of the highest possible quality! If you would like a common opal other than fire opal, or lighter or non-uniform opals, this is also possible and recommended. Everything is beautiful in nature!
Color
- Color intensity: Look for vibrant, intense color in opal. The most precious opals will have bright, saturated colors that immediately catch the eye. Deep, rich hues are often more popular than pale, dull colors. Basically, the brighter the fireworks, the more sought-after the stone.
- Variety of colors: An opal can present a range of colors, from blue, green and violet to red, orange and yellow, and even more subtle shades of pink and white. The wider and more varied the range of colors, the more attractive the opal. In other words, the more different colors the fireworks display, the more sought-after the stone.
- Uniformity: To be considered of good quality, opal must have a uniform color over its entire surface, with no spots or discolored areas. Uniform color distribution contributes to the stone’s overall aesthetics and value. Opals with areas of uneven color or visible imperfections that could affect its appearance, as they may appear duller and darker.

- Skin compatibility: Choose an opal color that complements your skin tone and personal style. For example, warm shades like red, orange and yellow can be flattering for warmer skin tones, while cooler shades like blue and green may be better suited to cooler skin tones.
Clarity
The clarity of opal refers to the transparency of the stone. A clear, limpid opal will allow light to pass through, highlighting its play of colors. If you want a luminous stone, avoid opals with too many or too obvious inclusions, as they can affect the stone’s beauty.
Playing with colors
Color play is a fascinating optical phenomenon that occurs when light refracts through the microscopic layers of opal, creating bursts of changing color. Look for opals with a dynamic, spectacular play of colors, with patterns and motifs that evolve when the stone is moved under the light.
In other words, a quality natural precious opal will have changing reflections as soon as you move it, and the light will give the impression of moving through the stone.
If the light doesn’t give the impression of moving, and the reflections remain the same in the same places in the stone regardless of orientation, chances are you’re looking at an imitation opal.
Brilliance
An opal’s brilliance refers to its ability to reflect light and sparkle when exposed to different light sources. The most brilliant opals will have an intense, vivid play of color, creating an effect of fire or light in the stone. Look for opals that sparkle and capture attention, even in varied lighting conditions.

Size and shape
Opal size and shape can also influence its appearance and value. Larger opals are often rarer and more precious, but this also depends on the quality of other aspects such as color and color play.
Shape has little impact on opal rarity. Opals can be cut in a variety of shapes, including oval, round, marquise and freeform. However, most quality precious opals will generally be cut with a flat base and rounded dome, such as cabochons, to better see the play of colors in the stone and protect it.

Geographical origin
Geographical origin is an important factor in the evaluation of opals, due to the variations in quality, color and specific characteristics associated with different regions of the world. Here is an explanation of the geographical origin of opals and its influence on their value:
- Australia: Australia is one of the world’s leading opal producers, and the country is renowned for its high-quality opals. Australian opals are extremely varied, from the precious white opal of Coober Pedy to the spectacular black opal of Lightning Ridge. Australian opals are often prized for their vibrant color play, clarity and rarity, making them some of the most sought-after opals on the market.


- Mexico: Mexico is another major opal producer, with deposits located in regions such as Querétaro, Jalisco and Guerrero. Mexican opals are known for their vivid, dynamic color play and unique color variations, from bright red to emerald green to electric blue. Mexican opals are also prized for their transparency and clarity, making them highly sought-after the world over.

- Ethiopia: Ethiopia has become an emerging opal producer in recent decades, with notable deposits in the Wollo and Shewa regions. Ethiopian opals are famous for their incredibly bright, multicolored play of colors, with hues ranging from red to green, yellow and blue. Ethiopian opals often feature unique color play patterns, such as flame splinters and fire beans, which distinguish them from opals from other regions.

- Other regions: In addition to these main producing regions, there are other places in the world where quality opals can be found, including Brazil, the USA, Slovakia and Hungary. Each region has its own unique characteristics in terms of color, color play and quality, contributing to the diversity and richness of opals available on the world market.
Assembled, synthetic and imitation opals: how to recognize them?
Where there’s sought-after stone, there’s also…imitation stone! And it’s best to know a thing or two about opals when buying a new piece of jewelry, as there are many pitfalls!
Assembled opals and how to recognize them
- Doublets : Doublets are composed of a thin layer of natural opal bonded to a darker base, usually made of a less precious material such as onyx (as in Sterling opals), common opal or synthetic stone. To identify them, carefully examine the edge of the stone for signs of bonding or layering between layers. Areas where the opal meets the base may reveal color differences or demarcation lines.

- Triplets: Triplets are similar to doublets, but with a third layer of quartz crystal or glass over the thin opal layer. Triplets can be more difficult to recognize, as the crystal layer can mask signs of bonding. However, look for signs of adhesive between the layers, especially on the edges of the stone. You can also view it from the side, which can highlight a transparent dome without any trace of opal or color play.
In the photos and videos below, observe the black base bonded to a very thin layer of natural opal, and topped by a transparent dome.

- Mosaic opals: Mosaic opals are made by assembling small pieces of natural opal to form a larger stone, then freezing them under a dome, as with the triplet. Examine the surface of the stone for signs of joints or seams between pieces. Separation lines or textural differences may indicate that this is a mosaic opal rather than a natural opal.

Synthetic opals (Gilson) and how to recognize them
Synthetic opals, such as those produced by the Gilson company, are created in laboratories and often look very similar to natural opals.
Although not, according to many gemologists, synthetic opals in the strict sense of the term (i.e. opals created in the laboratory using the exact process and materials of formation in nature, creating an identical look-alike in every respect), Gilson opals are the only ones accepted in some circles as such.
Here are a few clues to help you recognize them:
- Consistency and uniformity: Synthetic opals can sometimes exhibit an unusual consistency and uniformity of color, without the natural variations seen in natural opals.
- Color play patterns: Synthetic opals may have repetitive or artificial color play patterns not found in natural opals. Look for color play patterns that seem too perfect or symmetrical.
You’ll notice that the light remains fixed in the same places and that the play of color doesn’t give the impression of moving. It’s as if glitter had been implanted into the stone in a particular place. - Depth of pattern: Synthetic opals show their play of colors very much on the surface, whereas in a natural opal it will be distributed randomly throughout the stone.
Edit: I’ll be ordering a Gilson opal soon so I can take a detailed photo of it for you. Keep the article in a corner, it will be updated regularly!
Opal imitations and how to recognize them
- Other “synthetics” than Gilson opals and imitations : Synthetic” opals other than Gilson opals are laboratory-produced imitations of varying quality. They can be more or less easy to distinguish from natural opals.
They show signs of artificiality, such as repetitive, often polygonal color patterns reminiscent of reptile skin, a plasticized sheen or unusual uniformity. Among them are Aurora opals.

- Slocum glass: Slocum glass opals are another form of imitation glass produced in the laboratory using iridescent films embedded in silicified glass.
They can have similar characteristics to natural opals, and are a good alternative but may lack the realism and variety of color seen in real opals.

- Mexifire: The Mexifire® opal created by Rhea Industry is currently the closest imitation of natural fire opal, but with a lower density.
I’m also in the process of buying one, I’ll post the photos here! - Transparent Labradorite and Plastic: Transparent labradorite or plastic imitations similar to labradorite can be used to imitate the color play of opals. Layers of labradorite are usually visible.

How to recognize a natural opal: the recap
Verifying the authenticity of opals is crucial to ensure that you get a genuine, high-quality stone. Here are a few steps to follow to verify the authenticity of opals:
- Visual examination: Start by carefully examining the stone. Look for natural features such as inclusions, cracks or unique color play patterns. Authentic opals will often have distinctive features and “flaws” that testify to their natural origin.

- Color play: Authentic opals display a vibrant, changing play of colors when light strikes them from different angles. Rotate the stone under the light to observe variations in color and brightness. Beware of opals that appear static or lack dynamic color play, which could indicate that they are synthetic or imitation.
- Checking inclusions: Natural inclusions can often indicate the authenticity of an opal. Look for inclusions such as fractures, mineral impurities or color play patterns that are consistent with the opal’s natural characteristics. Synthetic or imitation opals may lack these natural inclusions.
- Common opals: Unlike “precious” opals, common opals show no play of color, making them very difficult to authenticate without gemological examination. In this case, it’s advisable to be wary of stones that are cut very cleanly and without scratches, as well as stones that are cut and embedded in jewelry that doesn’t protect them at all. Due to their low to medium hardness, natural common opals are more likely to be cabochon-cut, rolled into flat stones and protected by reinforced contours.

- Certificate of authenticity: When purchasing a precious opal, it is advisable to request a certificate of authenticity issued by a reputable gemmological laboratory. This certificate confirms the authenticity of the stone, as well as its specific characteristics such as weight, color and origin. Be sure to check the details on the certificate to make sure it matches the stone you are considering buying.
Opal jewelry: what to choose?
Opal ring
Opal rings are beautiful pieces of jewelry that can add a touch of sparkle and color to any outfit. However, due to opal’s low hardness on the Mohs scale, typically between 5.5 and 6.5, opal rings require special care in design and maintenance, and are not recommended for active wearers or daily wear.

- Protective setting mandatory: when choosing an opal ring, it’s essential to choose a setting that offers adequate protection for the stone. Bezel settings are often recommended as they completely surround the opal, reducing the risk of damage caused by impact or friction.
You can see an example of the closed setting in the image above! Note how the metal completely surrounds the stone to protect it. - Prefer assembled opals: In particular, opal triplets that cover natural quartz opal slices. Hardness will be improved and the surface protected from impact. As a bonus, it’s much cheaper than a whole natural opal.
- Beware of other rings: when wearing an opal ring, it is advisable to space it a finger or two apart from any other ring that could shock it during movement.
- Hand care products: Soap, hydro-alcoholic gels, creams and oils can be dangerous for opal, which is porous by nature. If possible, be sure to apply your products before wearing your ring, and take them off while you moisturize or disinfect your hands during the day. You can put it back on once your hands are dry.
Opal earrings
Opal earrings offer natural elegance and are the perfect complement to any outfit. Because of their location on the body, earrings are generally the most recommended because they are less exposed to shock and friction than rings and bracelets, but it’s still essential to choose settings that protect the stone well.

- Recommended protective settings: Bezel settings (see example above) are often considered the safest choice for opal earrings. These frames completely enclose the opal, offering extra protection against impact and friction. They are particularly recommended for fragile opals or those worn on a daily basis.
- But not mandatory: Claw mounts (below, note the metal claws that hold the stone) can be used for opal earrings, but it’s crucial to make sure they hold the opal firmly in place without leaving any exposed parts. Opting for claws that surround the stone well can help protect the opal from damage and minimize the risk of cracks or accidental falls.

- Pay attention to weight: When choosing opal earrings, be sure to also consider the weight and size of the stone in relation to the setting. An opal that is too heavy for the frame could cause excessive stress and increase the risk of damage.
- When applying perfume, remember to do so before wearing opal earrings, or to apply it away from them.
- Beware of hair oils: If you wear hair oils, remember to wait until they have dried before wearing your earrings. Remember to clean the stone in the evening.
Opal necklaces and pendants
Like earrings, opal necklaces and pendants require special attention. It is less demanding than the ring, even if the necklace can often fall prey to shocks.
(Believe me, I shocked my 1970 18-carat gold and amethyst necklace like the savage I am against my car door while vacuuming my seats at the laundromat. My clasp broke, my whole necklace fell in front of the vacuum cleaner and I didn’t realize it until I’d already vacuumed the clasp. Luckily I was able to get at my necklace before vacuuming it…but I still had to buy a new clasp. 70€ for the clasp. Never again)

- Recommended protective mounts: Bezel mounts are often considered the safest choice for opal necklaces and pendants. These frames completely enclose the opal, offering extra protection against impact and friction. They are particularly recommended for fragile opals or those worn on a daily basis.
- But not mandatory: Claw mounts (above) can be used for opal necklaces, but it’s crucial to ensure that they hold the opal firmly in place without leaving any exposed parts. It’s also best if they have a flat base that’s wide enough not to roll over and stick to your skin all the time. Opting for claws that surround the stone well can help protect the opal from damage and minimize the risk of cracks or accidental falls.
- Pay attention to weight: When choosing an opal necklace or pendant, make sure you also take into account the weight and size of the stone in relation to the setting. An opal that is too heavy for the frame could cause excessive stress and increase the risk of damage.
- When applying perfume, remember to do so before wearing the opal necklaces and pendants, and allow them to dry!
- Beware of hair oils: If you wear hair oils, especially if you have short or medium-length hair, remember to wait until they have dried before wearing your earrings. Remember to clean the stone in the evening.
Opal bracelets

Opal bracelets are a daring choice, as they are dangerous for the stone. As for the ring and necklace, here are the indications:
- It’s a no: All joking aside, bracelets are the most shock-prone piece of jewelry. In pure respect for the stone, its durability and therefore its eco-responsibility, we advise against wearing opal bracelets. However, it’s possible for the motivated and the careful, if you take the following points into account.
- Prefer assembled opals: In particular, opal triplets that cover natural quartz opal slices. Hardness will be improved and the surface protected from impact. As a bonus, it’s much cheaper than a whole natural opal.
- Prefer tight, protected bracelets: A bracelet that’s tight against the wrist will move less, and is less likely to bump into a car door or a pole. If you combine it with a bezel setting and a flat, stable base for each of the opals in the bracelet, you’ll reduce the risks considerably. Don’t forget the cuffs, which are worn over the biceps.

- Watch out for bead bracelets: I’m seeing quite a few ads for bracelets made from lots of strung “natural” opal beads. In view of the problems that already exist, and bearing in mind that a stone is capable of scratching itself, I strongly advise against it.
Likewise, I honestly think it’s unlikely that these stones are the real thing, especially when they’re sold so cheaply (but I could be wrong!).

- Choose bracelets with spaced stones: For the reasons given above, choose bracelets that space the stones with a closed setting and even intermediate links. This will reduce the risk of unintentional collision between them.
Choose bracelets with a single opal or a small number of opals on the top, but not in places that will shock against tables or the like!

- Watch out for everything: tables, chairs, products, oils, creams, car vacuums…
- Book for special occasions: For a special evening or event. You’ll know how to take care of it one evening and keep it intact… until the next big occasion!
Where to buy opal jewelry
Having not yet had the opportunity to purchase opal jewelry, I will update this article as I discover safe and responsible artisans and boutiques. Here are some general places where you can buy opal jewelry:
- Specialized jewelers: Jewelers specializing in opals are often the best place to find a selection of high-quality opal jewelry. They can usually offer specialized expertise and additional guarantees.
- Online boutiques: Many online boutiques offer a wide selection of opal jewelry, providing greater convenience and accessibility.
– Be sure to look for reputable stores with flexible return policies and detailed product descriptions. think of comparing the reviews on the net by typing the name of the store followed by “review”, this could save you a lot of disappointment!
– Avoid offers with inconsistent pricing (see lower price guide).
– And as always, when in doubt, it’s best not to buy. - Gem markets and jewelry fairs: Gem markets and jewelry fairs are excellent places to discover a variety of opal jewelry from different artisans and suppliers. You can often find unique, handcrafted pieces at competitive prices.
However, you can also find unscrupulous sellers. Using the list of questions to ask I’ve put together below, as well as the aids you can find above, it’s perfectly feasible! - Second-hand and upcycled jewelry: Buying second-hand or upcycled opal jewelry is an ecological and economical option. You can find vintage pieces in antique stores or specialized vendors, or opt for upcycled jewelry created from existing pieces.
How to buy ethically and eco-responsibly
When buying opal jewelry, it is important to consider the ethical and eco-responsible aspects of your purchase:
- Origin of opal: Find out about the origin of the opal used in the jewelry you are considering. Search for ethical and responsible opal sources that respect environmental and social standards. I’ll also be updating this article when I have something new to add, so remember to keep it to one side!
- Materials and manufacturing practices: Opt for jewelry made from sustainable, eco-responsible materials. Look for jewelers who use recycled metals and environmentally friendly manufacturing practices.
- Fair trade: Support brands and artisans committed to fair trade. Look for certifications or initiatives that guarantee fair and equitable working conditions for miners and artisans.
- Second-hand: When in doubt, second-hand jewelry is always a good choice!

By taking these considerations into account, you can make an informed and responsible choice when purchasing opal jewelry, while helping to support ethical and sustainable practices in the jewelry industry.
How much does an Opale cost? The price guide!
And now we come to the crux of the matter… price!
Unfortunately, you’ll find everything on the Internet, and that can quickly become confusing. That’s why I’ve summarized my research and knowledge on the subject in this little price guide, which should give you some pointers and help you avoid paying too much.
Note: These prices are, of course, for a cabochon-cut opal without jewels. To calculate the price of a complete piece of jewelry, remember to add the value of the desired metal or material, its estimated weight and, of course, a margin for the labor involved in creating the piece.
It goes without saying that the more you look for a reputable jewelry brand, the more you’ll pay the “popularity tax” and the more you’ll pay for their R&D centers, design team, marketing team and brand image rather than the product itself.
Budget and value of opal jewelry
As the market is constantly evolving, the prices below represent a general rule of thumb that I’ve observed over the last few months. Unlike diamonds, there is no regulated market for precious stones. an opal tends to be worth…what you’re willing to pay for it. Here is an overview of current prices per carat for different types of opal, with a distinction between Australian and Ethiopian precious opals:
- Australian precious opals: €80 to €500 per carat
- Australian opals are often considered among the most precious and sought-after in the world. Their rarity, spectacular color play and exceptional quality often justify higher prices.
- Australian white opals are generally valued at around €100 to €300 per carat, depending on their quality, color and play of colors.
- Australian boulder opals, which are natural opals embedded in bedrock, are also valued at around €100 to €300 per carat.
- Australian black opals, particularly rare and prized, are in a higher price range. They can be valued at around €300 to €500 per carat, and can rise to over €3,500.

- Ethiopian opals: €40 to €250 per carat
- Ethiopian opals are a more affordable yet beautiful alternative to Australian opals. They can offer impressive colors and lighting effects at more affordable prices.
- Prices for Ethiopian opals are generally lower than for Australian opals. You can expect to pay around half the price for Ethiopian opals of comparable quality.

- Mexican fire opal: €10 to €300 per carat
- Mexican fire opals, known for their play of warm, vibrant colors, range in price from around €80 to €300 per carat for quality specimens. Less colorful specimens can start at €10 per carat.

- Opal matrix and boulder: €1 to €50 per carat
- Black Australian boulder opals are the most expensive, but still affordable. Matrix and boulder opals from less recognized origins than Australia will generally be more affordable.

- Opal doublets and triplets: €10 to €100 per carat
- Opal doublets, which are combinations of natural opal and another supporting material (such as onyx, resin or plastic), are generally less expensive than solid opals. Prices can vary from €15 to €100 per carat, depending on the quality and provenance of the opal used.
- Opal triplets, which include an additional protective layer on top of the thin opal layer, are generally even less expensive, with prices ranging from €10 to €50 per carat for fine quality.

- Mosaic opals: €5 to €50 per carat
- I haven’t found a specific price for mosaic opals, but logically it shouldn’t exceed that of opal doublets or triplets, and should even be considerably lower, given that the opal piece present is not a single piece but several pieces assembled together.

- Common opal: €0.50 to €10 per carat
- These opals are the most common (no pun intended) and the least expensive (with the exception of fire opal) because they have no play of color within the stone.

I hope you know more! Feel free to leave a comment if you’d like more information and I’ll look into it.
Buying advice and warranties
Buying opal jewelry can be an exciting experience, but it’s important to take precautions to ensure you get a quality piece that meets your expectations. Here are a few buying tips and final recommendations to help you in your purchasing process:
Questions to ask your jeweller or dealer
- Where does opal come from? Find out where the opal used in the jewel comes from. Australian opals are generally considered the most valuable, while Ethiopian opals offer a more affordable alternative.
- What is the quality of opal? Ask about the opal’s quality, including color, color play, clarity and size. Reputable jewelers will be happy to give you details of the quality of their stones.
- Is it a natural opal or a synthetic or assembled opal? This will let you know whether the stone in front of you is worth its price or not. An honest seller must tell you everything about the treatments and origins of the stone you wish to buy. If in doubt, don’t buy!
- What type of frame is used? Find out about the type of setting and metal used in the jewelry. Make sure the frame is solid and secure. To do this, lightly shake the jewelry. If you feel the slightest movement of the stone, run away. You risk losing your stone or damaging it against the metal that is supposed to hold and protect it.
Make sure that the metal preferably surrounds the entire stone (Bezel mount) and that the metal is of high quality. To do this, press lightly on the edges of your jewelry. If the metal feels soft under your finger…run away. It needs to be thick enough not to deform easily, otherwise it will quickly warp and drop your stone. - What guarantees are offered? Ask what guarantees come with the jewelry, such as certificates of authenticity or quality guarantees. Make sure you understand the warranty conditions and what they cover.
- What is the return policy? Find out about the jeweler’s return policy in case you are dissatisfied with your purchase. Make sure you understand return times, conditions and any associated fees.
Warranties and return policies
- Certificates of authenticity: Look for jewelers who provide certificates of authenticity for their opal jewelry. This ensures that you get a genuine, high-quality opal.
- Satisfaction guarantee: Opt for jewelers who offer a customer satisfaction guarantee, allowing you to return the jewel if you’re not entirely satisfied with your purchase.
- Flexible return policy: Choose a jeweler with a flexible return policy that gives you enough time to inspect the jewelry and decide if it meets your expectations. This will also allow you to take my guide out and have a quiet look at it at home before deciding whether to keep it or return it!
- After-sales service: Make sure the jeweler offers a reliable after-sales service in case you need future repairs or maintenance for your opal jewelry.
- Find out for yourself about the jeweller or boutique before you buy: this is the most important part, because ultimately, you are responsible for your own purchases!
Type the name on the Internet followed by “review” to compare feedback from previous customers. It’s also the best way to weed out malicious merchants, as these will undoubtedly appear on reference sites such as Trustpilot, Que Choisir, etc.
If the business is new, it’s up to you. In my case, I always search for the name of the manager, his company, his share capital on Pappers, his sales policy (usually at the very bottom of the site, which should indicate his head office). If the store is vague about all the details, including delivery times, and there’s no proof of the advantages it claims (such as “made in france” or “fair trade” label), then you’ll probably be dealing with a dropshipper selling you random Chinese products.
It happened to me while looking for quality French products to push the search and come across a young man who had paid to have his headquarters in Paris and who insulted women (to whom he sold “French” products made in China) on his personal instagram … personally not the kind of people I want to buy from!
A business that has many good reviews and is cited by reliable sources (gemology journals, jewelry experts or gemologists, well-known review sites…) is more likely to satisfy you and will have more to lose if you leave a bad review later on. He’ll be in a better position to offer you reliable, high-quality services.
Ideas for combining opal jewelry with different clothing styles
- Bohemian style: pair an opal ring with sterling silver details with a flowing, bohemian dress for a casual, bohemian look. Add dangling opal earrings for an extra touch of femininity.
- Minimalist style: Choose opal jewelry with clean, simple lines, such as an opal pendant on a delicate chain, for a minimalist, modern look. Pair them with simple, monochrome outfits to highlight the beauty of the stone.
- Vintage style: Complete a vintage look with opal jewelry inspired by bygone eras, such as vintage opal brooches or dangling earrings adorned with floral motifs. Pair them with retro dresses and vintage accessories for an elegant, timeless look.
- Casual style: Add a touch of color and glamour to a casual look with opal jewelry. Opt for stackable opal bracelets or simple opal rings for a subtle touch of sophistication.
Recent trends in opal jewelry
- Multicolored opals: Multicolored opals, with their varied and dynamic play of colors, are increasingly popular in contemporary jewelry. Pieces featuring opals with vibrant colors and spectacular lighting effects are in great demand.

- Raw opals: Raw opals, which retain their natural shape and texture, are gaining in popularity for their organic, authentic look. Rings and pendants featuring rough opals have become popular choices for those seeking a unique, rustic look.

- Opals with mixed metals: Opal jewelry combining different metals, such as gold and silver, offers a bold, modern aesthetic. Mixed metal combinations add versatility to opal jewelry, allowing it to adapt to a variety of looks and styles.

Opal, other stones and metals: The best combinations
For the curious and those lacking inspiration, here are a few suggestions for combining metals and other stones to enhance each type of opal:
White opal
Metals: White gold or sterling silver are excellent choices for enhancing the brilliance and purity of white opal.
Other stones: Colorless, brilliant stones such as white diamonds, colorless topaz, white sapphires and moissanite can add brilliance and sparkle to a white opal, creating a subtle yet elegant contrast.
Black opal
Metals: Yellow gold or platinum highlight the rich nuances of black opal and add a touch of sophistication to the piece.
Other stones: Black stones such as black spinel, schorl and black diamond can complement black opal beautifully, adding depth and sophistication to the design.
Fire opal
Metals: Rose or yellow gold accentuate the warm, shimmering tones of fire opal, creating a vintage, romantic look.
Other stones: Garnets or citrines can complement fire opal beautifully, adding splashes of color that underline its vibrant play of hues. For ultra-vivid jewelry, it’s also possible to pair fire opal with frank turquoise stones such as paraiba tourmaline or turquoise itself.
Opal crystal
Metals: Platinum or white gold offer a subtle, sophisticated contrast with crystal opal, highlighting its clarity and luminosity.
Other stones: As with white opal, brilliant colorless stones such as white diamonds, colorless topaz, white sapphires and moissanite can add brilliance and sparkle to a crystal opal, creating an elegant, timeless look.

Caring for opal jewelry
Opal jewels are magnificent pieces that require regular care to preserve their natural radiance and beauty. In this tutorial, I’ll show you how to safely clean your opal jewelry to avoid damaging the stone. Here are the steps to follow:

Materials required:
- Warm water
- Mild soap (as natural as possible. Baby products are generally very good)
- Two soft chamois or microfiber cloths (one for washing and one for drying)
- Soft bristle brush (optional)
Steps :
- Preparation: Start by gathering all the necessary materials on a clean, flat surface. Make sure you have enough space to work comfortably.
- Pre-cleaning: Before you start cleaning, check your opal jewelry for any visible dirt or residue. If you notice dust or light dirt, use a soft cloth to gently wipe it away.
- Preparing the cleaning solution: Fill a small bowl with lukewarm water and add a small amount of mild soap. Mix well to create a light cleaning solution.
- Cleaning: Soak your clean cloth in the cleaning solution, wring it out and gently rub the surface of the stone. Alternatively, use a soft-bristled brush (like an old toothbrush) to gently scrub the surface of the opal and remove embedded dirt.
- Rinsing: Once you’ve finished brushing or scrubbing, rinse the soapy cloth with clean water until no soap remains. Wipe the surface of the stone with it to avoid leaving any traces of soap.
- Drying: Use a soft, clean cloth to gently dry the opal jewel. Gently dab the stone to remove excess water. Make sure the jewel is completely dry before storing or wearing it again.
Precautions to avoid damage
- Avoid wearing your opal jewelry during activities where it may be exposed to shocks or aggressive chemicals.
- Avoid exposing them to extreme temperatures, as this could damage the stone or adjacent materials.
- Remember to apply your perfume before wearing your opal.
- Avoid body oils and creams when wearing it.
Appropriate storage
- Store your opal jewelry separately from other jewelry to avoid scratches and damage.
- Use fabric-lined pouches or boxes to protect your jewelry when not in use.
- Avoid storing them in damp locations, as moisture can damage stone and metals.
