Physical properties

Formation & geological history

Formed from the petrification of mud or silicate-rich fluids in volcanic ash or sedimentary deposits. The unique patterns are caused by iron oxides and other minerals seeping into the rock during formation.

Uses & applications

Primarily used in jewelry (beads, cabochons), ornamental carvings, and as a healing stone in metaphysical practices.

Geological facts

Picture Jasper is often referred to as a 'global stone' or 'landscape stone' because its patterns often resemble deserts, mountains, or forests. The most famous variety is 'Biggs Jasper' found in Oregon.

Field identification & locations

Identified by its distinctive tan-and-brown banding and dendritic patterns that look like natural scenery. It is commonly found in the Pacific Northwest of the USA, Africa, and Brazil.
