Garnets are a group of nesosilicate minerals belonging to the garnet supergroup. The main garnet species are six, grouped into two isomorphous series (compounds having the same general formula and the same crystal forms but with different chemical composition): pyralspite (pyrope, almandine, spessartine) and ugrandite (uvarovite, grossular, andradite).
