Ametrine (natural bi-color Quartz) (Fantasy cut by Brett Kosnar)

Item Description

This is a beautiful, one-of-a-kind Ametrine gem from Bolivia. There are few gems in the world that are found in naturally occurring bi-colored examples. Ametrine is one 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 "Modified Elongated Octagon" cut with a 80/20 yellow to purple ratio along with superb internal clarity. This is a truly beautiful stone and when Ametrine is well cut, it looks amazing. The best aspect of this stone is that it has what is called a "Fantasy" cut, where the underside/pavilion/culet area of the gem has actually been carved to create the beautiful geometric patterns you see when the stone is viewed through the table. This particular style of cutting is seldom seen in any colored stones on the market today. The gem was cut by Brett Kosnar, who is a 4-time AGTA Spectrum Award winning gem. This stone is 100% untreated, no heating or irradiation, etc. 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.
