This Fox turquoise cabochon is all natural and unbacked.
The Fox Turquoise mine, once called the Cortez mine, is found in Lander County, Nevada. It was one of the largest producing mines in Nevada. The location was known to Native Americans in the area for centuries, but the first official claim was filed in 1914 by Charles Schmidtlein and Johnny Francis. Fox Turquoise can be found in various shades of green and blue with both sometimes occurring in the same stone.
