Sonoran Turquoise, like the White Water Turquoise, originates from the Campitos mine located on the Campitos Mountain outside of Cananea, Sonora, Mexico. This mine has been in production since the 1980's. Campitos turquoise, including the Sonoran Turquoise, is unique in many ways. The most impressive of which is the way it is mined. Most turquoise is mined from veins found in the surrounding stone. Turquoise from the Campitos Mountain is often found in clay deposits as nuggets. Sonoran Turquoise tends to have a brilliant green color with a matrix of brown and traces of pyrite which add a special sparkle to the stones.
