Blue Moon Turquoise Mine located in Nevada this mine is owned by some good friends I have known for years. They Mine the Material themselves and sell it directly to me. I find that to buy direct from the miners give me the best price and that added bonus of PROVENANCE. Provenance for those that are new to the business simply says my Blue Moon Turquoise can be tracked back to the mine and there is NO guess work as to where the material came from. Provenance is important because it adds value to the stone. 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.
