Genuine Apache Blue Turquoise set in Sterling Silver Ring. Created by Navajo Artist Lucy Valencia. Signed L. J. by the artist. The Apache Blue Mine turquoise mine, is a small mine with lots of potential. The mine is located near Tonopah, Nevada in the Candelaria Mountain range. In recent years the mine, (an open pit) has re-opened rendering Apache Blue turquoise with beautiful blue stones with eye popping black matrix. This high quality Apache turquoise is very rare and hard to find, even in this mine, but it's what every turquoise miner is searching for. Unfortunately only a small amount of this nice natural hard turquoise with really beautiful dark blue, webbed nuggets have been discovered. This turquoise is truly some of the nicest from Nevada.
