K2 takes its name from Mount K2 - Karakoram, at the border between Pakistan and China. The stone is a recent discovery and comes from the 2nd highest mountain range in the world - the Himalayas. K2 has the appearance of cream-colored granite, except for the blue circles that appear throughout the material. There is much debate about what the blue actually is. Some say Azurite or Afganite yet no-one has, as yet, been able to fully identify it.
