Physical properties

Formation & geological history

If garnet, it formed during metamorphism or in igneous rocks; garnets span a wide range of geological ages and commonly occur in schist, gneiss, and igneous deposits.

Uses & applications

Used in jewelry and, when not gem quality, as an industrial abrasive.

Geological facts

Garnet is a mineral group, not a single mineral; red stones can also be ruby, spinel, glass, or other materials.

Field identification & locations

The image shows a red polished cabochon but lacks diagnostic details. Hardness, refractive index, and gemological testing are needed for reliable identification; garnets occur worldwide.
