If anyone has some authentic olivine peridot from a pallasite that could be donated to the GIA the Gemological Institute of America's lab to have tested they could find the difference between the terrestrial and the meteoric type. They have a lab that studies and tests every type of gemstone that exists including man-made simulants and fakes and if they haven't already I'm sure they would love to study them and come up with a test at no cost other than the donation. I'm a gem cutter as well as a meteorite collector and enthusiast and have tried to find some unshattered pieces to cut for myself. Usually, the person trying to sell me the meteorite material has terrestrial gem material trying to be passed off as the pallasite olivine for a high price. Luckily because of my gemology and meteorite knowledge, I can tell the difference although a sure fire test for everyone would be great. If anyone has any they would like to donate and have tested ( I'm sure they'd love to work on it ) contact the GIA in Carlsbad, CA and maybe they can come up with a test to make it easier to separate the two. Also if anyone has any unshattered crystals and would like to have some material cut I can facet the material and even work out a trade type situation to keep it affordable if it helps. Anyway just a thought. I may look into it myself. Keep on Rockin Rock Heads, Sean Brooks #7781 FinestKindStones at gmail.com ShockwaveRoxx at gmail.com i Received on Wed 11 Jan 2017 01:50:58 AM PST |
