What is K2 Granite?
K2 Granite is a unique rock formation found in the Karakoram Range of Pakistan, specifically near K2, the second-highest mountain in the world.

The granite itself is typically a light color, often white or gray, providing a striking contrast to the azurite inclusions. The azurite forms as distinct, spherical orbs, giving the rock its distinctive appearance. K2 Granite is valued for its aesthetic appeal and is used in jewelry and ornamental objects.
