Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Black and white/tan stripes; Luster: Vitreous to waxy; Crystal Structure: Microcrystalline; Cleavage: None; Specific Gravity: 2.58-2.91

Formation & geological history

Formed through the metamorphism of sedimentary stones or volcanic ash, where various minerals create unique banding patterns over millions of years.

Uses & applications

Used primarily for jewelry, decorative carvings, tumbling, and as a popular stone for collectors and metaphysical practices.

Geological facts

Zebra Jasper is often called 'Zebra Stone' or 'Zebra Agate'. While technically an impure variety of silica, its distinct black and white lines are caused by heavy mineral inclusions.

Field identification & locations

Identify by its characteristic high-contrast 'zebra' stripes and lack of visible crystalline structure. Found commonly in Brazil, Russia, and India.
