Physical properties
Hardness of 6-7 on the Mohs scale, whitish-gray matrix with reddish-brown garnet crystals, vitreous to dull luster, granular crystal structure.
Formation & geological history
Formed through the slow cooling and crystallization of magma deep beneath the Earth's crust over millions of years.
Uses & applications
Used in architectural construction, countertops, decorative monuments, and as collector specimens.
Geological facts
Garnet is often an accessory mineral in felsic rocks like granite when the magma has incorporated aluminum-rich sedimentary material.
