Physical properties

Formation & geological history

Formed from the deposition of silica-rich sediments in alternating layers or through the infiltration of mineral oxides into cracks in a host rock. Often dates to the Precambrian or Paleozoic eras.

Uses & applications

Used primarily in lapidary arts for beads, pendants, cabochons, and decorative ornamental carvings. Highly valued in the metaphysical community as a grounding stone.

Geological facts

Despite the name, Zebra Jasper is often technically a type of siltstone or marble rather than a true jasper, but it is traded under the Jasper name due to its opacity and hardness. It is frequently sourced from Western Australia.

Field identification & locations

Identify in the field by its distinct high-contrast linear banding and smooth, waxy texture when wet. Found commonly in Australia, Brazil, Russia, and India. Collectors look for sharp, clean transitions between the black and white bands.
