Polished brecciated jasper (likely)

Jasper, an opaque microcrystalline variety of quartz (SiO₂), with angular mineral fragments cemented in silica

AI-generated identification · may be incorrect

Hardness about 6.5–7 Mohs; mottled pink, cream, and brown; opaque with a waxy to vitreous polish. Quartz is trigonal and has no cleavage; the image does not show diagnostic features clearly enough to confirm the identification.

Physical properties

Formation & geological history

Silica-rich fluids cemented or replaced fragmented rock, producing a brecciated pattern; jasper forms in many geological periods and settings.

Uses & applications

Used for beads, cabochons, ornaments, and other lapidary items; not generally an industrial stone.

Geological facts

Jasper’s colors and patterns come from impurities and inclusions; polished pieces can make identification less certain from appearance alone.

Field identification & locations

The opaque, irregularly mottled pattern is consistent with brecciated jasper, but a closer view or hardness/streak tests would help distinguish it from other patterned stones. Jasper occurs worldwide, including in the United States, India, and Madagascar.
