Note: There are also white, green, yellow, brown, and black
varieties. The garnet is a silicate, the bases being
aluminia lime (grossularite, essonite, or cinnamon

(almandine), or aluminia manganese (spessartite), or
iron lime (common garnet, melanite, allochroite), or

transparent red varieties are used as gems. The garnet
was, in part, the carbuncle of the ancients. Garnet is
a very common mineral in gneiss and mica slate.
