The Kingman turquoise mine, operated by the Colbaugh family in Arizona, 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.
This Kingman turquoise cabochon is stabilized and backed for ease of setting.
