Where to find Leopard Skin Jasper
Mexico
A significant source of Leopard Skin Jasper, particularly the rhyolitic variety, often found in volcanic regions.
United States (various states)
Deposits have been found in states like Oregon, California, and Idaho, often associated with volcanic or hydrothermal activity.
Africa (e.g., Madagascar, South Africa)
Some varieties of orbicular jasper, including those resembling leopard skin patterns, are found in these regions.
Collecting tips
- Geological Maps. Consult geological maps for areas known for rhyolitic extrusions or significant jasper deposits. Look for regions with past volcanic activity or hydrothermal alteration.
- Stream Beds and Alluvial Deposits. Leopard Skin Jasper, being relatively hard and resistant to weathering, can often be found as tumbled pebbles or cobbles in stream beds and alluvial deposits downstream from its source.
- Outcrops and Road Cuts. Exposed rock faces in volcanic terrains or areas with sedimentary chert/jasper beds are good places to search. Look for distinctive patterns on weathered surfaces.
- Tools. A rock hammer, chisel, and safety glasses are essential for collecting from outcrops. For stream beds, a shovel and sieve might be useful.
Quick Check
- Color:
- Cream, tan, orange, red, brown base with black, grey, red, or brown 'spots'.
- Luster:
- Dull to waxy to vitreous (when polished).
- Streak:
- White (for both rhyolitic and jasper varieties, as the primary component is silica).
