Kingman

The Mineral Park Mine,(Kingman Turquoise Mine,) is located in the Acerbate Mountains 14 miles northwest of Kingman, Arizona. It is the last remaining commercially producing mine in the United States. Evidence suggests turquoise was mined in the surrounding areas dating as far back as 600 AD. Tools like stone hammers were found in the ancient trenches and tunnels running through the hills in 1962.

The quality natural Kingman turquoise produced at this mine is generally medium blue with a "water web" matrix that easily distinguishes it from other turquoise. The best turquoise is a lovely blue with a black web matrix. The Kingman mine also produces a variety of turquoise ranging from pale green to blue with red, brown or yellow matrix.
