Physical properties

Formation & geological history

Formed through the deposition and compaction of silica-rich sediments or volcanic ash in ancient environments, often altered by hydrothermal solutions over millions of years.

Uses & applications

Commonly used in lapidary arts, tumbled stones, beaded jewelry, carvings, and as a decorative ornamental stone.

Geological facts

Despite being called jasper, it is technically an opaque, impure variety of microcrystalline quartz or sometimes a fine-grained banded siltstone. The striking contrast gives it a resemblance to zebra stripes, highly favored in metaphysical and crystal healing communities.

Field identification & locations

Easily identified by its distinct brown and white striping and high polish retention. Found worldwide with notable deposits in India, Australia, and Africa.
