Natural Nevada turquoise cabochon lot of 1 high grade cab from the Blue Spider turquoise mine. Weight  12.5cts. as rare as it comes, location has been mined over, I have all that is left. 'Most all my turquoise is backed for strength when set into jewelry. ALL turquoise is mined and cut in the USA, no treating, stabilizing or outright fake turquoise. Be very careful of the many 'to good to true' deals on the internet. Real natural turquoise is becoming very scarce. Most of the material I see for sale are outright rip offs. I have been in the turquoise business for over 50 years and it hasn't changed much, let the buyer beware. I personally mined most of the turquoise I will be selling and if I did not, I know the miner that did.Closed my website at the end of 2022 . My remaining inventory will be sold here on Ebay, many very rare and high grade stones will eventually be made available, some one of a kind. Also be wary of "certified", by who? Several of these "companies" are somewhat loose with their certifications ($)...All my orders are shipped by Insured Priority Air Mail, USA only, FREE....
