Polished/tumbled multicolored stone, possibly jasper

Likely opaque microcrystalline quartz (chalcedony/jasper); exact identification is uncertain because the image is out of focus

AI-generated identification · may be incorrect

Rounded, polished surface with mottled green, yellow, red, and brown colors; likely vitreous to waxy luster and no visible cleavage. If jasper, hardness is approximately 6.5–7 Mohs and specific gravity about 2.5–2.7.

Physical properties

Formation & geological history

Jasper forms when silica-rich fluids replace or cement fine sediments or volcanic material, commonly during hydrothermal alteration. Its age depends on locality and may range from Precambrian to recent.

Uses & applications

Used as a decorative stone, cabochon, bead, palm stone, and inexpensive collectible; occasionally used for small carvings and inlay.

Geological facts

The color pattern may resemble fancy jasper, ocean jasper, or picture jasper, but those varieties cannot be distinguished reliably from this blurred photograph.

Field identification & locations

Test for glassy hardness by seeing whether it can scratch ordinary glass, and inspect for granular or waxy texture; jasper is opaque, unlike most agate. Common sources include India, Madagascar, Brazil, Mexico, and the western United States.
