Comment: Disclosure: We do usually not copy/paste our product descriptions, but in this case we need to repeat the following: Blue Zircon (from Cambodia) has been the one gem that I regretted not to trade because they are always heated. Now, I was told that an Australian gold-miner found these light blue Zircons as by-product in his mine. I was more than intrigued and after some study I'm willing to trust: the blue is very bright, the stones are all very small, they show no sign of high-heat, and there are actually reports of natural bright blue Zircons found in Australia. We conclude that these Zircons had the luck to undergo a natural geological heat process like some Citrines but that they are untreated by men.

About the gem: Extremely bright blue Zircon with a tint of green. Trillion, IMO, being the ideal shape for a sparkle-gem. Paraiba-like glow combined with adamantine lustre: see handshot! Inclusions are visible only under the lens; note, the fuzziness 'inside' the gem is a result of its high dispersion not of an unclean crystal. Full IGI report, transport, grading papers, and rainforest protection in price included. The finite supply of these natural blue Zircons recommends a purchase a soon as your gem funds allow.
