Item Description

There are not many gems which are found in naturally occurring bi-colored examples. One of those stones is Ametrine, 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 bi-color gemstones. The best stones come from the Anahi Mine in the eastern Bolivian jungle, and despite popular belief, they are not mined in Brazil. The stones are mined in Bolivia and taken across the border into Brazil where they are faceted and then they are sold with "made in Brazil" stickers on them, but no Ametrine has ever been found in Brazil. This particular gem has a "Bar Cushion" cut with a nearly 50/50 yellow to purple ratio along with superb 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, good-sized, colorful, naturally occurring/untreated gemstone.
