9.20 Carat Natural Loose Bicolor Ametrine Stone Emerald Cut Brazilian Gemstone

Mined from the famous gem-bearing deposits of Brazil, this 9.20 Carat Natural Loose Bicolor Ametrine features a seamless, perfectly balanced dual-color split within a single quartz crystal, pairing the rich royal purple of amethyst with the warm golden-yellow of citrine. Precision-crafted into an architectural emerald cut, its clean rectangular silhouette, clipped corners, and parallel step facets create a mesmerizing "hall-of-mirrors" optical effect that sharply delineates and highlights the distinct color boundary. The gemstone boasts superior eye-clean clarity and exceptional crystal transparency, allowing light to traverse fluidly through its crystalline body without dark extinction zones or cloudiness. Completely natural, unheated, and untreated, this pristine 9.20-carat Brazilian ametrine offers rare natural bi-color artistry with ideal statement proportions, making it a sophisticated centerpiece for an East-West set ring, a bespoke pendant, or an elite fine gemstone portfolio.
