No reserve price - 1 pcs Green, Yellow Tourmaline paraiba - 1.13 ct - Guild Gem Laboratory

Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Its wide color range makes it a favorite among gem collectors and jewelers. The Green and Yellow Tourmaline variety, often associated with the Paraiba region, is prized for its vivid colors and brilliance, though true Paraiba tourmalines specifically contain copper and manganese which give them a distinct neon-like blue to green coloration. This particular 1.13-carat specimen demonstrates the lovely color play tourmalines can showcase, blending green and yellow hues that bring a vibrant yet natural appeal. Tourmalines generally form in metamorphic and igneous rocks and crystalize in elongated prisms, making them suitable for diverse cuts. Their relative hardness and unique pleochroism—showing different colors when viewed from different angles—make them a fascinating choice for collectors and those interested in the mineral's geological story as well as appealing aesthetics.
