Formation & geological history

Forms from silica-rich fluids filling cavities and fractures in volcanic or sedimentary rocks. The distinct patterns are caused by impurities and inclusions, often iron oxides or organic material.

Uses & applications

Primarily used as a gemstone in jewelry making and for lapidary work. It is valued for its unique, landscape-like patterns.

Geological facts

Picture Jasper is often referred to as 'landscape stone' due to its scenic patterns. It is believed by some to have grounding and stabilizing properties in crystal healing.

Field identification & locations

Identify by its opaque nature, earth-tone colors, and intricate patterns resembling landscapes or abstract art. Commonly found in areas with past volcanic activity, such as the western United States.
