The Pauite Turquoise mine shares a mountain with the Godber / Burnham /Drycreek Turquoise mine in central Nevada. The Pauite mine produced limited quantities of high-grade Turquoise. It has a wide graduation of blue tone, from light to dark, with web or matrix in colors of black, orange, brown, and red. I purchased my material from Tony Cotner who pasted away in 2016 took the location of the mine with him and to this day has not been found. Tony was very selective about who he sold his beloved Paiute Turquoise to and I was lucky enough to be included in the group of famous Native American and Japan's gold and silver smiths. The Son and I do all the cutting work we never farm it out. We are Native American gem cutters, we are registered members of the federally recognized Native American tribe Wichita Indians out of Oklahoma.
