Gorgeous champagne zircon loose gemstone. The gem is large and weighs 8.26 cts. It measures 9.8 x 12 mm. I bought this champagne zircon over 16 years ago, it is from a mine in Vietnam that is no longer producing this material. Zircon is an all natural stone known for it's high dispersion level. Not all zircon shows high dispersion though, only the top grade gems from Vietnam show zircons true colors. This gem is one of those top grade stones. In sunlight this stone looks like it has Christmas lights inside of it because of the high dispersion level. The only thing that compares would be a champagne diamond. Zircons of this quality and carat weight are very scarce and expensive in the market place. Comes with a certification from the Chanthaburi Gemological Research Institute in Thailand. This stone was also cut in Thailand, with amazing step cutting on the pavilion which brings out the dispersion and brilliance. A true gem in every sense of the word, from RareExotics.
