Physical properties
Hardness of 6.5 to 7 on the Mohs scale, with a vitreous to dull luster. Displays distinct contrasting dark black or brown and white or cream-colored zebra-like stripes.
Formation & geological history
Formed through the deposition and compaction of silica-rich sediments in ancient aquatic environments over millions of years. Often associated with volcanic ash alterations.
Uses & applications
Widely used in lapidary arts for making tumbled stones, cabochons, beads, decorative carvings, and holistic crystal healing jewelry.
Geological facts
Despite its trade name, Zebra Jasper is technically an opaque, patterned variety of microcrystalline quartz or chalcedony rather than a true jasper.
Field identification & locations
Identified by its striking banded black and white patterns and high hardness that scratches glass. Commonly sourced from deposits in Africa, India, and Australia.
