10.09 Ct. Alexandrite from Tanzania

Among the most evocative and rare color change gemstones we offer at The Natural Gemstone Company is a GRS certified orangy pink alexandrite, 10.09 carat, oval shape, measuring 13.70 by 10.96 by 8.36 mm. This transparent greenish to orangish alexandrite displays a true and dramatic color change between daylight and incandescent light, a hallmark of fine alexandrite, and it has been expertly cut in a mixed brilliant faceted style to maximize life and fire. Clarity has been graded very slightly included, evaluated at eye level, allowing the gem to retain exceptional brilliance, and its color intensity is intense with an excellent polish that speaks to the artistry of the cutter. There is no enhancement, and the stone is of Tanzanian origin, making it an uncommon and sought after find from East Africa, certified by GRS to reassure the discerning collector. At 10.09 carat this alexandrite occupies a rare size bracket for stones of this quality, and because it is singular in our inventory it embodies exclusivity for the client who chooses it.

Alexandrite has a storied heritage, first prized for its chameleon like nature and adopted by royal jewelers in the 19th century as a symbol of luck, balance and transformation, and examples like this recall the antique rings and pendants worn as family heirlooms and talismans. In traditional practice alexandrite was favored for signet rings and personal amulets because its color change was thought to mirror the fortunes of the wearer and to mark important life transitions, and contemporary connoisseurs continue to value the stone for those very associations. For the jeweler or collector seeking a centerpiece for a bespoke commission, this alexandrite offers technical and aesthetic perfection, from well proportioned measurements to a mixed brilliant cut that flatters both modern and period settings. The Natural Gemstone Company invites serious buyers to request the GRS report and detailed images, and to consult with our atelier about custom mounting options that will transform this singular Tanzanian alexandrite into a legacy jewel reserved for an exclusive, discerning owner.
