This magnificent 14.05-carat natural green zircon sourced from the rich gem gravels of Tanzania represents an extraordinary pinnacle of rarity and size. While zircon is celebrated for its diamond-like fire and high refractive index, discovering a vivid green specimen of this magnitude—let alone one that is completely clean and optimized for high-end faceting—is a once-in-a-generation occurrence.Exhibiting an enchanting, rich forest-green body color free of excessive brownish masking, this exceptional piece possesses pristine transparency. Size, Clarity and Color... promising a finished cut stone with breathtaking brilliance, exceptional light return, and vibrant dispersion. Completely unheated and untreated, it retains its 100% earth-mined integrity, making it a stellar centerpiece for a collector.Gemstone Specifications:Cut Analysis & Expected YieldZircon has a high refractive index (1.92–1.98) and strong birefringence (double refraction). To prevent a "sleepy" or blurry look from the double refraction, the stone should ideally be cut with the table perpendicular to the optic axis. Given its rectangular/oval elongated outline (13.4 × 9.6 mm) and excellent depth (8.2 mm), here are the best faceting strategies:Modified Cushion BrilliantBest overall choice. The deep pavilion (8.2 mm) perfectly fills out a cushion's belly. It maximizes weight retention while using brilliant-style crown facets to explosive effect against zircon's high dispersion.40% – 48%5.60 – 6.70 ctsRadiant / Barion CutBest for modern brilliance. Combines step-cut silhouettes with brilliant-style pavilion facets. This maintains the rectangular length while creating an intense "crushed ice" sparkle that masks any minor color zoning.38% – 45%5.30 – 6.30 cts
Classic Oval BrilliantHighest potential brilliance. Softens the corners dramatically. While it requires shaving off more corner weight from the rough, it creates an exceptionally lively stone with excellent light return.35% – 42%4.90 – 5.90 ctsEmerald Cut (Step Cut)Best for classic elegance. Highlights the flawless clarity and rich forest-green color. However, step cuts show less fire (dispersion) than brilliant styles, which doesn't fully exploit zircon’s diamond-like optical properties.I would Suggest Your primary focus should be orienting the stone to minimize the visual doubling of facets caused by birefringence, and keeping the pavilion angles around 40°–42° to avoid center windowing.
