Bisbee Turquoise is one of the most beautiful types of Turquoise that has ever been taken out of the ground in North America. It's striking true blue color ranges are spectacular and the chocolate matrix that the Turquoise is found in, extentuates it's beauty. Bisbee Turquoise is some of the finest Arizona Turquoise and there is no Turquoise on earth that is comparible to Bisbee Turquoise, as it has it's own unusual charicteristics that are unique only to itself.
The Bisbee Mine was originally founded in the mid 1870's and by 1975 when it was closed had become the largest and richest mine the world has ever known. Taking out over 8,000,000,000 pounds of copper the mine was given the name "The Copper Queen". The Bisbee Mine also produced nearly 3,000,000 ounces of Gold. Mining at Bisbee did not include mining for gemstones, any Turquoise or other gemstone materials were discarded by the mining companies and prohibited to be taken out by the minors due to liability reasons.
In the late 1950's, a deposit of Turquoise was found in the Lavendar Pit region of the Bisbee Mine. Most of this Turquoise was hauled off to an area where they dumped their waste and over burdens from the mining project. Individual Minors recognized the beauty of the Bisbee Turquoise and would sneak small amounts of the Turquoise out in their lunch boxes and/or what ever other means they could muster. It was not long after Bisbee Turquoise was discovered in the Mine that it was introduced to the Southwestern Jewelry Industry. By the early 1960's, Bisbee Turquoise had become the finest Turquoise the market had ever seen and demand for it went through the roof. Again, the mining of Turquoise at the Bisbee Mine was restricted and only small amounts were able to be taken out and sold to the Jewelry industry.
In 1972, the one and only lease ever given to work the dumps from the Lavendar Pitt was awarded to Mr. Robert Matthews of Durango, Colorado. Bob and his associates worked the dumps hard for approximately two years to recover less than 2,000 pounds of good to excellent quality Bisbee Turquoise. Due to mining restrictions and the cost of recovering the Bisbee Turquoise from the dumps, mining slowed down and ended by 1980.
