Likely garnet gemstone

Garnet-group silicate; species cannot be determined from the photo (common red varieties include almandine, Fe₃Al₂(SiO₄)₃, and pyrope, Mg₃Al₂(SiO₄)₃).

AI-generated identification · may be incorrect

Small, dark red, polished oval cabochon with a glassy luster; garnets have Mohs hardness 6.5–7.5 and cubic crystal structure, but cabochon cutting hides cleavage and crystal form. Identification from appearance alone is uncertain.

Physical properties

Formation & geological history

Garnets form in several rock types, especially metamorphic rocks; some varieties also occur in igneous rocks and alluvial deposits. Their ages depend on the host geology and cannot be inferred from this image.

Uses & applications

Used in jewelry and, when not gem quality, as an abrasive for waterjet cutting and surface finishing.

Geological facts

Garnet is a mineral group, not a single mineral; color and composition vary widely.

Field identification & locations

Confirm with refractive index or specific gravity testing; common sources include India, Sri Lanka, Madagascar, and East Africa. The image shows no scale or diagnostic features.
