K2 Azurite Sphere

1.76" / 44mm 125g / 0.276lbs / 4.41oz K2 Stone is found in the foothills of the second highest mountain on Earth, K2 in the Karakoram mountain range which borders Pakistan and China. K2 Stone is a combination stone characterized by vivid blue or green “spots” in a mottled granite matrix. Although K2 Jasper is the most commonly used name for marketing this material, it is definitely not jasper. If you examine the rock with a magnifying glass, you will see cleavage faces of feldspar minerals and black flakes of biotite. It is a bright white granite that contains sharply contrasting orbs of bright blue azurite. The white granite is very fine-grained and composed of quartz, sodium plagioclase, muscovite, and biotite. Some specimens show strong alignment of the biotite grains and could be called "granite gneiss."
