NAVAJO HANDCRAFTED EXTRA LONG DANGLE EARRINGS Spiny Oyster Shell (orange and reddish colors) Living Spondylus shells are, indeed, very spiny, but the polished product looks very smooth, with some of its color variation strongly resembling that of the Blood Oyster. The resemblance is strong enough that it’s important to ask, when purchasing these materials, if they’re from Blood Oyster or Spiny Oyster. Artists often use Spiny Oyster as a substitute for Blood Coral. Although not nearly as rare as the Blood Coral or Rose Coral, divers collect Spiny Oyster by hand, making the work laborious and relatively expensive, with some risks. Kingman Turquoise The Kingman mine in northwestern Arizona was one of the largest turquoise mines in North America. The terms "Kingman" or "high blue" refer to the blue color usually displayed in this stone. It has become a color standard in the industry. The mine became famous for its rounded, bright blue nuggets with black matrix. Few turquoise mines produced nuggets, especially of this quality. Old natural Kingman Turquoise is rare. The Colbaugh's own this mine and the Turquoise Mountain mine, their company name is Colbough Processing. They have recently gone back into the section of the Kingman mine and are digging and bringing some new Natural Kingman Turquoise.
