Where to find K2 Jasper
Skardu area, Northern Areas, Pakistan
The primary and most well-known source of K2 Jasper is near the base of K2 Mountain (Mount Godwin Austen) in the Skardu region of the Northern Areas of Pakistan. This remote and high-altitude location is where the unique granite with azurite inclusions was first discovered and mined.
Collecting tips
- Geological Context. Look for granitic intrusions in areas known for copper mineralization. The presence of hydrothermal alteration zones can be a good indicator.
- Visual Identification. The most distinctive feature is the stark contrast between the white/gray granite and the vibrant blue azurite spots. Malachite, if present, will appear as green spots.
- Hardness Test. The granite matrix will be hard (Mohs 6-7). The azurite (Mohs 3.5-4) and malachite (Mohs 3.5-4) inclusions will be softer than the surrounding granite.
- Acid Test (Caution Recommended). Azurite and malachite are copper carbonates and will effervesce (fizz) when a drop of dilute hydrochloric acid is applied, releasing carbon dioxide. This test should be done with extreme caution and only on a small, inconspicuous area, as it can damage the stone.
Quick Check
