The Kingman mine in northwestern Arizona was one of the largest turquoise mines in North America. The terms “Kingman” or “high blue” refer to the blue color usually displayed in this stone. It has become a color standard in the industry. The mine became famous for its rounded, bright blue nuggets with black matrix. Few turquoise mines produced nuggets, especially of this quality. Old natural Kingman Turquoise is rare. The Colbaugh’s own this mine and the Turquoise Mountain mine, their company name is Colbough Processing. They have recently gone back into the section of the Kingman mine and are digging and bringing some new Natural Kingman Turquoise.
