Ametrine (natural bicolor Quartz)

Item Description

This is a unique variety of Quartz from the finest occurrence in the world. Ametrine is a naturally occurring purple and yellow bi-color variety that is formed by a unique twin law ("Brazil Law Twinning") where two separate individually colored crystals are intergrown to form an alternating "radiation" pattern of purple and yellow triangles when viewed down the c axis. The two colors are oriented to cut the bicolor gemstones, This particular gem is a unique, one-of-a-kind, attractive, well cut, 55/45 purple/yellow bicolor, virtually eye clean, "Concave Quantum Emerald" cut gemstone. The majority of the stone is yellow, but there is a slight amount of purple in one corner. This gem is truly beautiful and when Ametrine is well cut, it looks amazing. It has come to my attention that the mine is no longer in production of this material and the market has quickly "dried up". Don't miss this opportunity to own a unique, colorful, large, naturally occuring gemstone with this unque cut.
