Cloud Mountain Gem Grade Fine Blue Spiderweb I
The Cloud Mountain claim is located in the Hubei Province, in central China and has been the most prolific mine in Asia. The Mohs hardness ranges from a 4 to 5.5. The qualities that come from Hubei range from very soft material, needing to be treated to make it usable, to an attractive green spider web, to a very hard and fine blue with dark veined (spider web) matrix that could be considered some of the world’s finest turquoise.
