Physical properties
Hardness of 6.5 to 7 on the Mohs scale, characterized by distinctive dark brown or black zebra-like stripes against a white or pinkish background, with a vitreous to dull luster.
Formation & geological history
Formed through the deposition of silica-rich sediments in ancient marine or terrestrial environments, subsequently lithified and altered by tectonic pressure over millions of years.
Uses & applications
Widely utilized in the creation of polished decorative stones, tumbled pocket stones, cabochons for jewelry, and lapidary art.
Geological facts
Despite its trade name, zebra jasper is technically an opaque, patterned variety of chalcedony or marble rather than a true jasper.
Field identification & locations
Easily identifiable by its striking banded or striped contrast, commonly sourced from regions such as Australia and India.
