Item Description

There are few gems in the world that are found in naturally occurring bi-colored stones. Ametrine is such gem, which is a unique bi-colored variety of Quartz. The material gets its name from the combination of purple AMEthyst and yellow citRINE within in the same stones. The two separate individual colors are naturally intergrown within the crystals 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. The best stones come from the Anahi Mine in the eastern Bolivian jungle, and despite popular belief, they are not mined in Brazil. This particular gem has a "Pear Cabochon" cut with a 40/60 yellow to purple ratio along with good internal clarity. This is a truly 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, naturally occurring/untreated gemstone. Priced at $750.00 retail.
