Physical properties

Formation & geological history

Formed from sedimentary processes where silica-rich fluids permeate through sedimentary deposits or volcanic ash. The distinctive banding occurs as different mineral impurities (like manganese, carbon, or iron) settle in distinct layers over millions of years. This specimen likely originates from the Precambrian or Paleozoic eras.

Uses & applications

Used primarily in lapidary arts, jewelry (cabochons, beads), and decorative interior design. It is popular for ornamental carvings, worry stones, and as a collector's specimen for those interested in banded patterns.

Geological facts

Despite Being called 'Jasper', it is often more geologically similar to a patterned marble or a banded chert. In the metaphysical community, it is often referred to as the 'Anti-Apathy Stone', though geologically its fame comes from its high-contrast aesthetic which mimics a zebra's coat.

Field identification & locations

Identify in the field by its high-contrast black and white stripes and its ability to scratch glass (hardness test). It is most commonly found in deposits in Australia, Brazil, Russia, and the United States (specifically Utah). Collectors look for sharp, distinct color transitions without muddying between the white and black layers.
