Let's Talk Turquoise

Kingman Mine

The copper mining operations in the historic Mineral Park area near Kingman, Arizona, have produced substantial quantities of turquoise in prehistoric and modern times. The production amounts of Kingman’s blue colors along with Sleeping Beauty’s similar hues have made this color of turquoise the most common “look” of ay American turquoise. Discovered by James Haas in the late 1800s, this area became world famous for turquoise when Leonard W. Hardy marketed it during the 1950s, ’60s, and ’70s. The Duval Corporation’s open-pit mining operations originally leased the turquoise rights to L.W. Hardy. Since then, the Colbaugh family has controlled these claim rights for several generations. The Cerbat Mountains in Mohave County, at an elevation of about 3,300 feet, have two main areas of turquoise deposits, including Aztec Peak (Turquoise Mountain) and Ithaca Peak. Turquoise from this area has been marketed using the names Kingman, Ithaca Peak, and Turquoise Mountain.

      Looks like a cool nugget. There are a lot of cool nuggets in the world, some natural and some not. The largest natural nugget that I have seen weighs over two thousand pounds and is in a private collection in China. Americans have a lot to learn when it comes to who has what in the world. I would bet from what I have seen in China that the top 100 largest nuggets in the world.

  3. Iam not a fan of Kingman Turquoise it is a nice blue but usually not very hard so it does not hold its color. This goes for most American
    Turquoise. Pursian Turquoise is usually much harder and denser so it holds it color. i was cutting and polishing Turquoise back in the1970s
    and still have a lot of Turquoise from back then

      As with all mines, there is low grade to high grade in their production. It’s unfortunate that you have only dealt with low grade Kingman, there is also high grade Kingman. On the other hand it is great that you got to work with high grade Persian turquoise rather than the low grade Persian turquoise. What were some of the other mines that you have been able to work with?
