6.70 Carat Natural Loose Bicolor Ametrine Stone Fancy Cut Brazilian Gemstone

Mined from the famous gemstone deposits of Brazil, this 6.70 Carat Natural Loose Bicolor Ametrine displays an extraordinary, seamless fusion of golden citrine and rich purple amethyst within a single crystal. Precision-crafted into an artistic fancy cut, its innovative facet design plays upon the stone's dual-color zones, casting lively, alternating flashes of violet and honeyed amber across the crown. The gemstone boasts superior eye-clean clarity and exceptional crystal transparency, allowing light to flow fluidly through its custom proportions without cloudy veil inclusions or dark extinction zones. Completely natural, unheated, and untreated, this distinct 6.70-carat Brazilian jewel combines artistic lapidary technique with rare natural color zoning, making it an ideal centerpiece for an avant-garde designer ring, a custom pendant, or a modern gemstone collection.
