Varieties of garnet ||types of Garnet

Garnet is the name for a group of minerals that have common properties. All family members have very similar structures, but varying enormously in chemical composition and properties. The name Garnet is derived from the Latin granatum, meaning seeds of pomegranate, referring to the red color of a Pyrope and Almandine varieties. Garnet family is divided to two sub-groups, Pyralspite which is Calcium-free garnet and Ugrandite which is Calcium rich garnet. Almandine (iron-aluminium silicate), Pyrope (magnesium-aluminium silicate), and Spessartine (manganese-aluminium silicate) are the main members of Pyralspite sub-group and Grossular (Calcium-aluminium silicate), Andradite (calcium-iron silicate) and, Uvarovite (calcium-chromium silicate) are the members of Ugrandite sub-group.
