Physical properties

Formation & geological history

Silica-rich fluids filled or cemented fractured rock, with iron oxides producing warm colors; later tumbling exposed the pattern. Such deposits form in many ages and geological settings.

Uses & applications

Used for beads, cabochons, and decorative objects; common material for lapidary practice and collecting.

Geological facts

Jasper is prized for varied patterns, and trade names often describe appearance rather than a distinct mineral species.

Field identification & locations

Look for opaque, fine-grained material with irregular colored bands or breccia-like fragments and a glassy polish; similar jasper occurs worldwide. A small tumbled stone like this is commonly worth about $2–$10 USD.
