K2 Sten - Trumlad
A new and rather amazing manifestation of Azurite—in combination with Quartz, Feldspar and Biotite—is the recently discovered stone known as K2. Its name is derived from the fact that it was discovered and is mined in northern Pakistan, in sight of the world’s second-highest mountain, K2. These stones have the appearance of a normal, cream-colored granite, except for the surprising blue circles (spheres, actually) that appear throughout the material. The blue spherical inclusions have been identified as Azurite that somehow grew within the surrounding Quartz, Feldspar and Biotite.
