Collecting tips
- Look for Sedimentary and Volcanic Terrains. Jasper, including Leopard Skin Jasper, is often found in areas with a history of silica-rich sedimentation or volcanic activity. Check riverbeds, alluvial deposits, and weathered outcrops.
- Examine for Distinctive Patterns. The key identifying feature is the 'leopard skin' pattern. Look for orbicular or spotted inclusions within a fine-grained, opaque matrix.
- Test Hardness. Jasper is relatively hard (Mohs 6.5-7). It will scratch glass and steel. This helps differentiate it from softer look-alikes.
- Observe Fracture. Jasper typically exhibits a conchoidal (shell-like) fracture, which is characteristic of cryptocrystalline quartz.
Quick Check
- Color:
- Cream, tan, orange, reddish-brown base with black, grey, brown, or red spots/orbs.
- Luster:
- Dull to waxy.
- Streak:
- White (due to its quartz composition).
