Formation & geological history

Formed from silica-rich fluids precipitating in rock cavities or replacing other minerals. Often found in sedimentary or volcanic environments.

Uses & applications

Used in lapidary work for making cabochons, beads, and ornamental items. Popular among collectors.

Geological facts

Jasper is an opaque variety of chalcedony. The striking orange spots are likely due to iron oxide inclusions.
