Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Black, white, grey, and brown banding; Luster: Vitreous to waxy; Texture: Fine-grained and opaque; Cleavage: None.

Formation & geological history

Formed through the deposition of silica-rich fluids in sedimentary environments, often over millions of years, gaining its stripes from rhythmic deposition or subsequent metamorphic staining.

Uses & applications

Primarily used as a decorative stone, in jewelry (beads, cabochons), and as a popular tumbled stone for collectors and spiritual practitioners.

Geological facts

Despite the name 'jasper', many specimens sold as Zebra Jasper are actually types of banded marble or travertine, but the variety shown is typically a densly packed quartz variety.

Field identification & locations

Identify by its distinct high-contrast parallel or wavy stripes resembling a zebra pattern. Most commercial specimens are sourced from Brazil, Africa, or India.
