Physical properties

Typically Mohs 6.5–7; opaque orange with a smooth, waxy-to-dull luster and no visible crystal faces. The photo shows a rounded, polished piece; exact mineral identity cannot be confirmed visually.

Formation & geological history

Forms as iron-rich silica fills cavities or replaces material in volcanic and sedimentary settings. Jasper deposits occur in rocks of many ages; the specimen’s age and source cannot be determined from the image.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and collecting; not generally used as an industrial quartz source.

Geological facts

Jasper is a trade name for opaque, patterned chalcedony, and its colors commonly come from iron-bearing impurities.

Field identification & locations

Look for opacity, fine texture, and hardness sufficient to resist scratching by a steel knife; orange color alone is not diagnostic. Common sources include India, Brazil, Madagascar, and the western United States.
