Physical properties

Formation & geological history

Jasper forms as silica-rich fluids deposit or replace material in rock, with iron and other impurities creating its colors. It occurs in many geological ages and settings; the pendant’s source cannot be determined visually.

Uses & applications

Used for cabochons, pendants, beads, and decorative objects; jasper is also collected as ornamental stone.

Geological facts

Jasper is a broad trade name for colorful, opaque chalcedony rather than one precisely defined mineral species.

Field identification & locations

Typical clues are opacity, smooth polish, and patterned color; verify identity with tests or gemological examination, since similar stones can look alike. Jasper occurs worldwide, including India, Brazil, Australia, and the United States.
