Some interesting info from Geology.com

"K2 Granite," also known as "K2 Jasper," is an extremely interesting rock and lapidary material from Pakistan side of the Himalayas. It is a bright white granite that contains sharply contrasting orbs of bright blue azurite. The azurite orbs range from a few millimeters up to about two centimeters in diameter. On a broken surface or on the surface of a slab, the blue orbs look like drops of bright blue ink that splashed onto the rock. Upon closer examination, however, you will see that they are actually spherical in shape.

K2 granite is named after a mountain in the Karakoram Range near the border between Pakistan and China. K2, also known as "Mount Godwin Austen," is the second-highest mountain in the world. The azurite granite is found in colluvium near the base of the mountain. It is in a very remote area visited by very few people.

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. Examination of the azurite spheres with a good hand lens or microscope reveals that the azurite is present along mineral grain boundaries, within tiny fractures, and penetrating the feldspar grains. The azurite is a secondary material that clearly formed after all of the other minerals in the granite had solidified from the parent melt.
