Natural ametrine is one of the gemstone world’s most fascinating optical wonders — a rare blend of golden citrine and royal amethyst formed naturally within a single crystal. This impressive 11.01 carat emerald cut ametrine showcases bold color zoning with luminous flashes of honey gold and rich violet, creating a gem that feels both earthy and luxurious at once. The elongated emerald cut enhances the stone’s clarity and depth, allowing the natural color transition to become the centerpiece of the design.
At approximately 17x11mm, this earth mined loose gemstone offers exceptional presence for a custom ring, pendant, or collector’s piece. Its crisp faceting and substantial size make it ideal for statement jewelry while still maintaining the refined elegance that emerald cuts are known for. A gemstone this size and quality is not only visually captivating, but also increasingly difficult to source in natural material — making it a striking choice for anyone seeking a rare and conversation-worthy gem.
