Description

Garnets are known for their dark red coloring and distinct habit, yet the garnet group encompasses six different end members of silicate minerals, which all form one large group of isotropic minerals. The end memberspyrope, almandine, spessartine, grossular, andradite, and hydrogrossulareach carry their own distinct characteristics that are determined by the environment in which they are formed. Garnets tend to have a white streak, vitreous luster, and either dodecahedral or trapazohedral habit. This poster will describe the physical make-up and optical properties of garnets, as well as the geologic conditions that form this unique mineral group.
