Physical properties
Hardness: 6.5-7.5 (Mohs), Color: Deep red to purplish-red, Luster: Vitreous to sub-adamantine, Crystal system: Isometric, Cleavage: Indistinct/None
Formation & geological history
Formed under high temperatures and pressures in metamorphic rocks like schist or through crystallization in igneous environments.
Uses & applications
Primarily used in jewelry when of gemstone quality; also utilized as an industrial abrasive for waterjet cutting and sandblasting.
Geological facts
Garnet is the birthstone for January. While most famous for being red, it can actually occur in almost every color, including green and orange.
Field identification & locations
Check for high refractive index and lack of cleavage. In jewelry, look for deep red saturation and clarity; in nature, they often form dodecahedral (12-sided) crystals.
