Natural Nevada  turquoise cabochon lot of 4 cabs. Total weight 12.3cts. 4 small dark blue beauties from the Blue Spider Mine, 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. I had on online website called "The Turquoise Farm' for over ten years, closing 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....Check our BLOG page for lots of information on Natural Turquoise: https://theturquoisefarm.blogspot.com
