Bi-Color Tourmaline Pair

Pair of natural Bicolor Tourmalines of Brazilian origin, with a green to pink-lilac color transition in a single crystal — a rare and highly valued phenomenon in gemology. Rectangular cut (emerald cut) with calibrated proportions, ensuring a perfect fit for symmetrical jewelry such as earrings and necklaces. Total weight of the pair: 6.22 ct. Calibrated stones 10×5×2.5 mm, ideal for mounting in sterling silver (925) or 18k gold. Each stone features the bicolor characteristic with a green zone at the base and pink-lilac at the top, a result of the variation in chemical composition during crystal growth.
