The Black Web Gem Mine is a tiny turquoise mine located in Esmeralda County, Nevada. Production is very very small, but the stones this mine produces are amazing. The range of colors from this mine go from lovely sky blues to some of the bluest blues and darkest black webbing you'll find anywhere, and it's all natural turquoise! This wonderful material has been featured in Joe Dan Lowry's book 'Turquoise: The World Story of a Fascinating Gemstone', both in the English language and in Japanese. It has also been featured as one of the classic, high-grade Nevada mines in the Japanese magazine: 'Lightning', Vol. 199. We work this mine with our partner, Philip Chambless, so you know you're getting this stone straight from the source!
