Where to find Leopard Skin Jasper

Another significant source, often yielding material with good contrast.
United States (various states)
Deposits have been found in states like Oregon, California, and Idaho, often associated with volcanic activity.
Africa (various countries)
Some African nations also produce varieties of patterned jasper that can resemble Leopard Skin Jasper.
Collecting tips
- Look for Silica-Rich Environments. Search in areas known for volcanic activity, hydrothermal alteration, or sedimentary beds that have undergone silicification. Look for outcrops of chert, chalcedony, or silicified volcanic rocks.
- Examine Riverbeds and Gravel Pits. Water erosion can expose and transport jasper nodules. Riverbeds, stream banks, and gravel pits are good places to find tumbled pieces.
- Check for Distinctive Patterns. Leopard Skin Jasper is identified by its unique orbicular or spotted patterns. Look for rocks with contrasting circular or irregular markings against a lighter background.
- Test Hardness. Jasper is relatively hard (Mohs 6.5-7). It should scratch glass and not be easily scratched by a steel knife. This helps differentiate it from softer look-alikes.
Quick Check
- Color:
- Cream, tan, reddish-brown, or grey base with contrasting red, black, brown, or dark grey spots/orbs.
- Luster:
- Dull to waxy, sometimes vitreous on fresh breaks.
- Streak:
- White (due to its quartz composition).
