Physical properties
Hardness of 6.5-7.5 on the Mohs scale, deep red to black color, vitreous to resinous luster, isometric crystal system, and no distinct cleavage.
Formation & geological history
Forms mainly in metamorphic rocks like schist and gneiss through regional metamorphism, as well as in igneous pegmatites under high temperature and pressure.
Uses & applications
Widely used as an abrasive in waterjet cutting and sandblasting, as well as a popular gemstone in jewelry.
Geological facts
Garnets have been used since the Bronze Age as gemstones and abrasives, and the name originates from the Latin word granatus, meaning grain.
Field identification & locations
Easily identified by its distinctive dodecahedral or trapezohedral crystal habits, high hardness, and lack of cleavage. Commonly found worldwide in metamorphic terranes.
