Natural Ametrine from Bolivia, light color of both Amethyst and Citrine giving the stone a nice pink tone (No treatment what so ever). The shape is called a Heptagon (Seven Sides). Good brilliance with some ghost floating around created by the carving. This is a 13+mm stone so it is nice and large, ideal solitaire pendant. I have provided several photos with different angles, the last photo shows the stone full face up under diffused  lighting. The stone is internally flawless. Any dark colors seen are only external reflections and are not in the stone. This shape fits nicely is a square basket type finding. Gorgeous piece...
