All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite.

The word garnet comes from the 14th‑century Middle English word gernet, meaning 'dark red'. It is borrowed from Old French grenate from Latin granatus, from granum
