A one-of-a-kind 29.22 carat bicolor tourmaline offered loose for world-class collectors and connoisseurs who pursue rarity, presence, and natural color artistry. This exceptional gemstone displays a striking two tone composition with a seamless transition that shifts in character as light moves across the crown, making it a true collector’s treasure and an extraordinary centerpiece for bespoke jewelry. A Rare Tourmaline With Natural Color Theater Bicolor tourmalines are prized for their natural color zoning, formed during crystal growth as trace elements changed over time. In a gem of this scale, the visual effect becomes dramatic and unmistakable, with distinct hues that still blend elegantly into a refined gradient. The result is a gemstone that feels alive, nuanced, and impossible to replicate. Precision Cut for Brilliance and Balance Expert cutting enhances both brilliance and the bicolor transition, preserving symmetry while allowing the colors to present cleanly. The gem’s size and presence make it ideal for collectors who appreciate investment grade stones and for clients seeking a signature jewel that cannot be duplicated. Design Your Dream With Merkaba Jewelry Beverly Hills This tourmaline is perfectly suited for a bold statement ring, a museum worthy pendant, or an heirloom bracelet. Choose platinum, 18K yellow gold, or 18K white gold, and elevate the design with diamond accents or complementary color stones, or keep it minimal to let the tourmaline remain the focus. Our atelier specializes in translating rare gemstones into one of a kind creations with meticulous craftsmanship.

This unique gemstone is celebrated for its exquisite beauty, as it harmoniously combines hues in a way that distinguishes it from other tourmaline varieties.
