There are a ton of black sapphires on eBay, but if you can buy one that is not resin-impregnated you have a real jewel. Virtually all of the current supply in the market is treated. I have this 7.15 carat beauty from old stock and I am proud to offer it here on the bitcoin forum. For someone who is interested in untreated and truly rare gemstones, this is a spectacular star sapphire that is beautiful for the centerpiece in your collection or as a piece of fine heirloom-quality jewelry.
This gemstone is completely untreated. It has not been heated or resin-impregnated. It was mined here in Thailand in Chanthaburi province near Bangkacha mountain. These stones are extraordinarily hard to find untreated and of such a high quality with a superb star.
Of course as with any gemstone that we offer you can order a laboratory report for this stone. I am happy to get you a report from AIGS, GIA, GRS, Tokyo Gem Lab, Hallmark, or any other laboratory here in Bangkok. The cost depends on the lab as each one is different. I am confident that this stone is untreated and natural and would welcome a laboratory's opinion on the matter!
