Natural Tanzanite Diamond Halo Pendant

An Exceptional Collector's Jewel

Few gemstones have captured the imagination of collectors and jewelry connoisseurs quite like Tanzanite. Found exclusively in the foothills of Mount Kilimanjaro, Tanzania, this remarkable gemstone is celebrated for its extraordinary blue-violet color, exceptional rarity, and limited geographic origin. With only a single known commercial source in the world, Tanzanite has become one of the most coveted colored gemstones of the modern era.

This magnificent pendant showcases an impressive 19.86-carat Natural Tanzanite, displaying the highly desirable AAA Royal Blue "D-Block" color sought after by collectors. Its rich bluish-violet body color is complemented by remarkable flashes of electric blue and violet as the gemstone moves in the light, creating a brilliance and depth that few gemstones can rival.

Expertly fashioned into a classic cushion cut and surrounded by a halo of brilliant natural diamonds, this exceptional gemstone is beautifully presented in an elegant 18K white gold pendant. The diamond halo enhances the vivid color of the Tanzanite while adding brilliance and sophistication to an already extraordinary piece.

Acquired during the late 1990s from renowned gemstone dealer Frank M. Circelli, this pendant represents an exceptional example of premium Tanzanite from an era when some of the finest material ever recovered from the Merelani Hills entered the marketplace. Large Tanzanites approaching twenty carats with this level of color, clarity, and craftsmanship are increasingly difficult to obtain, making this pendant both a remarkable work of jewelry and an exceptional collector's acquisition.

Whether worn as an elegant statement piece or preserved as part of a distinguished gemstone collection, this extraordinary Tanzanite pendant embodies rarity, timeless beauty, and enduring value.
