Ametrine (cut by Brett Kosnar)

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 gem 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 based upon their position inside the crystal to create the famous bicolor gemstones. This particular gem is a great, one-of-a-kind, excellent quality, 40/60 purple/yellow bicolor, virtually eye clean "Brilliant Trillion" cut gemstone. This is a beautiful stone 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. This gem was cut by Brett Kosnar in June of 2010.
