Physical properties

Formation & geological history

Formed through the cooling of magma (granite) which was later subject to secondary mineral deposition where copper-rich fluids formed azurite droplets. It is specifically found in the foothills of K2, the world's second-highest mountain.

Uses & applications

Primarily used in jewelry making for beads, cabochons, and decorative carvings. It is highly valued in the metaphysical community and by mineral collectors for its unique appearance.

Geological facts

Despite the name 'K2 Jasper', it is geologically a granite, not a jasper. The blue spots are actually Azurite, a copper carbonate, which is very rare to find naturally occurring within a granite matrix.

Field identification & locations

Identify in the field by looking for the 'dalmatian' contrast of blue spots against a white/grey crystalline background. It is almost exclusively found in the Skardu area of northern Pakistan near the base of K2.

Dark Igneous Rock (Likely Basalt or Diabase)

Basalt (extrusive igneous rock) or Diabase (intrusive igneous rock - also known as Dolerite), largely composed of plagioclase feldspar, pyroxene (augite), and sometimes olivine and amphibole. Exact mineralogy would require thin section analysis.
