      calcium chromium garnet found as small, brilliant, green crystals. It is the rarest of all the garnets, and its crystals commonly are too small to be cut. Otherwise, it would rival emerald as a popular gemstone because of its beautiful colour. Typical occurrences are in chromite, as in the northern Urals, California, Canada, Finland, and Silesia in Poland. For details of chemistry and occurrence, see garnet.
