The garnet is a silicate, the bases being aluminia lime ( grossularite essonite, or cinnamon stone), or aluminia magnesia ( pyrope), or aluminia iron ( almandine), or aluminia manganese ( spessartite), or iron lime ( common garnet melanite allochroite), or chromium lime ( ouvarovite, color emerald green). The 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.
