Physical properties
Hardness: 6-7 on Mohs scale (due to granite matrix), Color: Light grey to white granite with distinctive bright blue spots of azurite, Luster: Vitreous to dull, Crystal structure: Trigonal (azurite) and interlocking crystalline (granite matrix), Specific Gravity: ~2.6-2.8
Formation & geological history
Formed through the intrusion of hydrothermal fluids containing copper into cracks and pores within a granite pluton, creating secondary azurite crystals within the host rock.
Uses & applications
Primarily used as a lapidary material for polished stones, cabochons, carvings, and in metaphysical crystal healing jewelry.
Geological facts
Despite often being called K2 Jasper, it is not actually jasper; it is a unique combination of granite and azurite found only near the base of the K2 mountain in Pakistan, the second-highest mountain in the world.
Field identification & locations
Easily identified by the striking contrast of round, vibrant blue azurite spots embedded in a grey and white speckled granite background. Sourced mainly from the Karakoram mountain range in northern Pakistan.
