Physical properties

Formation & geological history

Formed through the secondary mineralization of azurite within a pre-existing granite base. This unique combination occurs in the high-altitude conditions of the Himalayas near the foot of the K2 mountain peak.

Uses & applications

Primarily used as a decorative gemstone for jewelry, carvings, spheres, and tumbled stones. Highly sought after by spiritual practitioners and mineral collectors.

Geological facts

Despite its common name, it is technically an igneous granite rather than a sedimentary jasper. It was only relatively recently discovered and is found in one of the most remote locations on Earth.

Field identification & locations

Look for distinctive blue spots that appear to be 'stained' onto a grey-and-black speckled granite background. It is primarily found in the Skardu area of northern Pakistan.

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.
