Red jasper (likely)

Jasper, an opaque microcrystalline variety of quartz (SiO₂), colored red by iron oxides

AI-generated identification · may be incorrect

The specimen is opaque, brick-red to orange with lighter bands and a polished surface. Quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage; specific gravity is about 2.6.

Physical properties

The specimen is opaque, brick-red to orange with lighter bands and a polished surface. Quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage; specific gravity is about 2.6.

Formation & geological history

Jasper forms when silica-rich fluids fill cavities or replace sediments, with iron oxides producing its color. Its age and exact geological setting cannot be determined from the image.

Uses & applications

Used for cabochons, beads, carvings, and decorative objects; also collected as a lapidary material.

Geological facts

Jasper is a chalcedony, made of extremely fine intergrown quartz crystals; banding can develop as mineral-rich layers accumulate.

Field identification & locations

The opaque red color, waxy-to-glassy polish, and possible bands are consistent with jasper, but visual identification alone is not definitive. It occurs worldwide in silica-rich volcanic and sedimentary settings.
