Red jasper (possible)

Microcrystalline quartz, SiO₂, colored red by iron oxides; the image alone cannot confirm the identification.

AI-generated identification · may be incorrect

Opaque, deep red, with a rough, irregular fracture and likely dull to slightly waxy luster. Quartz hardness is 6.5–7 Mohs; jasper is microcrystalline and has no visible crystal faces or cleavage.

Physical properties

Opaque, deep red, with a rough, irregular fracture and likely dull to slightly waxy luster. Quartz hardness is 6.5–7 Mohs; jasper is microcrystalline and has no visible crystal faces or cleavage.

Formation & geological history

Jasper forms when silica-rich fluids deposit and consolidate microcrystalline quartz, with iron oxides providing color. It occurs in many geologic ages and settings, including volcanic and sedimentary rocks.

Uses & applications

Used for cabochons, beads, carvings, and decorative objects; small rough pieces are chiefly collected as curiosities.

Geological facts

Jasper is a variety of chalcedony, not a distinct mineral species. Red color commonly comes from hematite or related iron oxides.

Field identification & locations

A uniform opaque red color and hardness near 7 support jasper; this tiny fragment is insufficient for reliable identification. Jasper occurs worldwide, including India, Australia, Brazil, and the United States.
