The Bisbee mine, "the Lavender Pit", near Bisbee, Arizona, is one of the more famous of the American mines because Bisbee turquoise (also known as "Bisbee Blue" registered name) was one of the first put onto the market. The turquoise mine is part of the Bisbee copper mine (The Copper Queen), the main operation of the site.
Bisbee turquoise has developed a reputation as a hard, finely webbed or dendrite, high blue stone, known for its "chocolate brown" matrix. Bisbee turquoise also comes in a beautiful dark green color. Because most of this turquoise has already been mined and what is left is in limbo due to circumstances with the copper mining in the open pit, it is one of the most highly collected stones. Most jewelry being made with this stone today is being made via the orders of the current owners of the mine.
The rest, such as ours which is all hand cut and mounted by Durango Silver Co. Is found through old "stashes" or collections that have been obtained.
