Type of Garnet

• Spessartite is a type of garnet. There are six different species of garnet also including uvarovite, andradite, pyrope, almandine and grossular. Garnets are usually made up of six and eight-sided crystals, which are composed of silica minerals. Garnets in general have a low cleavage compared to other gemstones, meaning they don't break apart easily. Garnets of this type that aren't gemstone quality are used as abrasives for their hardness and durability.
