K2 is found in the foothills of the second highest mountain in the world. It can be found bordering Pakistan and China. Because of this it is a rarer crystal as it is harder to mine.
K2 vibrates a powerful energy, which makes it an excellent stone for healing. The blue marks on the stone are azurite and this gives it its celestial quality and the other part of the stone is granite which offers a grounding and stabalizing property. Put the two together and it gives you the benefit of a peaceful mind.
