Magnificent 4.046 ct Natural Cushion Cut Teal Sapphire – Bellerophon Certified – Completely Unheated Presenting a premier investment-grade collector’s gemstone: an extraordinary 4.046 Carat Natural Bi-Color Teal Sapphire, officially certified by the renowned Bellerophon Gemlab (Place Vendôme, Paris). This substantial gemstone is completely unique, possessing a rich and moody Deep Greenish Blue body that beautifully opens up to display a brilliant, glowing golden-yellow eye right at its crystalline core when exposed to light. Expertly faceted into an elegant cushion cut with ideal 8.76 x 8.70 mm facial proportions, the stone exhibits strong fire, structural brilliance, and excellent face-up transparency. Most importantly, this sapphire has No Indications of Heating, preserving its color exactly as nature created it over millions of years within basaltic mineral deposits. Stones of this scale (exceeding the critical 4-carat mark) that remain completely untreated are increasingly difficult to source on the global market. A breathtaking centerpiece choice for an exclusive, custom-designed high-jewelry piece or a stellar addition to an estate gem collection.
