Tourmaline, a diverse gemstone from the tourmaline family and more specifically the elbaite tourmalines, emerges in specific geological conditions, generally within metamorphic and igneous rocks. Pink to red elbaite tourmaline forms, then a change occurs in the fluids surrounding it when iron comes into play. The crystal’s creation then turns from red to green, creating a flamboyant center and green bark, earning it the name watermelon.

Uncut watermelon tourmaline crystals present nature’s unrefined elegance, their raw beauty captivating the imagination. These crystals often feature concentric rings of green and pink, mimicking the appearance of watermelon slices.
