“Garnet” denotes a group of minerals.<\/p>\n

Structurally, they are all insular silicates and have a similar crystal structure, which means that they are chemically related. The name is derived from the Latin term “granum” for “grain”. On the Mohs scale<\/a>, they have a hardness between 6 and 7.5, depending on their composition.<\/p>\n
