Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque luster, distinct black and white or dark brown zebra-like striping, trigonal crystal system.
Formation & geological history
Formed from ancient silica-rich mud or sediment deposits that underwent lithification and hydrothermal alteration over millions of years.
Uses & applications
Primarily used for ornamental carvings, polished stones, cabochons, and metaphysical crystal collections.
Geological facts
The striking contrast is caused by iron oxide and other mineral impurities trapped during the rock's formation.
Field identification & locations
Easily identified by its opaque, zebra-striped pattern and high hardness; commonly sourced from India and Africa.
