Physical properties

Formation & geological history

Jasper forms when silica-rich fluids fill cavities or replace rocks, with iron oxides producing red coloration. Deposits occur in many ages and settings, including volcanic and sedimentary rocks.

Uses & applications

Used for beads, jewelry, carvings, and ornamental objects; jasper is also collected as a lapidary material.

Geological facts

Jasper is opaque, unlike many translucent varieties of chalcedony, and its colors and patterns vary with mineral impurities.

Field identification & locations

Red color and opaque, polished appearance are consistent with jasper, but glass and dyed stones can look similar; inspect for natural texture, inclusions, and uniformity. Jasper is found worldwide, including India, Brazil, Australia, and the United States.
