Physical properties

Formation & geological history

Formed through the infiltration of silica-rich fluids into volcanic ash or fine sedimentary layers. The 'pictures' are created by the rhythmic precipitation of iron and manganese oxides during dehydration and metamorphism of the silica.

Uses & applications

A popular lapidary material used for cabochons, jewelry, interior decor items, and as a pocket stone for collectors. Its unique patterns make it highly desirable for artistic jewelry pieces.

Geological facts

Picture Jasper is often called 'the stone of global awareness' by metaphysical collectors. The specific desert-like patterns are actually Liesegang rings produced by the periodic precipitation of impurities rather than actual fossilized landscapes.

Field identification & locations

Identify in the field by its opaque nature (unlike agate), signature brown and tan banding, and high hardness (it will not be scratched by a steel knife). Commonly found in the Pacific Northwest of the USA (notably Oregon) and parts of Africa/India.
