The terms "Kingman" or "High Blue" refer to the blue color usually displayed in this stone.

The Kingman Mine area was first mined for turquoise by Navajos dating back to 600 AD. 

The Mine became famous for its rounded, bright blue nuggets with black matrix.

The Kingman nuggets are a magnificent contributor to modern turquoise.
