Ametrine (polished slice)

Item Description

This is a very 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. This is how the two colors are oriented to cut the bicolor gemstones. This particular piece is a unique, one-of-a-kind, purple/yellow bicolor, gemmy polished slice of Ametrine. This is a truly beautiful piece and is really unusual for Quartz in general. 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 piece of this interesting material. Well worth the $100 starting bid!
