Physical properties
Hardness of 6-7 on the Mohs scale, with distinct reddish-brown and white or cream-colored alternating bands. It has a dull to waxy luster and a microcrystalline structure.
Formation & geological history
Formed through the accumulation and diagenesis of fine-grained silt and clay sediments, with later geochemical redistribution of iron oxides. Most famous specimens date to the Precambrian period.
Uses & applications
Primarily used for ornamental carvings, decorative objects, and lapidary jewelry due to its striking banded patterns.
Geological facts
Authentic zebra rock is extremely rare and geographically restricted, primarily originating from the Ord Ranges in Western Australia. The striking patterns are a result of secondary chemical alteration rather than original depositional bedding.
Field identification & locations
Easily identified by its bold, zebra-like alternating bands of contrasting colors. Collectors can find polished specimens globally, though raw material is strictly regulated.
