Physical properties

Hardness of 6.5-7 on the Mohs scale, with a vitreous to dull luster. It features distinct white and dark brown or black banded patterns.

Formed through the deposition and compaction of silica-rich sediments over millions of years in arid environments.

Commonly used for ornamental carvings, polished towers, beads, and decorative lapidary items.

Despite its name, zebra jasper is technically an opaque variety of chalcedony or marble rather than true jasper.

Easily identified by its signature zebra-like stripes, it is globally sourced with notable deposits found in India and Africa.
