The Kingman mine is recognised as one of the oldest and largest turquoise mines in America, widely known for producing highly collectable gemstone grade turquoise. Kingman turquoise is distinguished by its unique lustre, striking characteristics and sky-blue colour. Turquoise is the December birthstone.
