The calcium-aluminum variety of garnet, grossularite, cinnamon stone or essonite, is less used in jewelry than those above mentioned. It is usually yellow to brown in color, but may be rose red or pink, as in the specimen from Mexico shown in the accompanying plate. The yellow grossularites resemble in color the gem known as hyacinth and are sometimes sold in place of the latter, but true hyacinth is much heavier and doubly refracting. About the only essonites or cinnamon stones available for gems come from Ceylon. These are of good size and color. Those from Italy, shown in the accompanying plate, are too small to cut into gems, but surrounded as they are by light green chlorite and pyroxene, they make very pretty mineral specimens. Grossularite is almost always found in crystalline limestone. Green garnets are of two kinds, the calcium-iron garnet, known as demantoid, and the calcium-chromium garnet known as uvarovite. The demantoid garnets come only from the Urals. They have a rich green color and make beautiful gems when good ones can be found. The name demantoid refers to the diamond-like luster which they possess. The stone is also known as “Uralian emerald.” Uvarovite, named for Count Uvarov of Russia, also makes valuable gems if found in pieces of sufficient size and luster. It is found in Russia, in Pennsylvania and in Canada. Garnet has long been the birthstone of the month of January. “By her who in this month is born No gems save garnets should be worn. They will insure her constancy, True friendship and fidelity.” Such are the virtues ascribed to the garnet. That the stone has been known and used from the earliest times I have already remarked. Under the name of carbuncle mention is made of it in the literature of all ages, its impressive feature being usually the brilliant, fiery light which it gives forth. According to the Talmud, the only light which Noah had in the ark was afforded by a carbuncle, and there are many Oriental tales regarding the size and brilliancy of carbuncles owned by the potentates of the East. Occasionally carbuncles were engraved, and some fine garnet intaglios are still known. The greater abundance of the stone in modern times has led to its being less highly prized than formerly, and to its being put to other uses than mere adornment, but it perhaps contributes more largely to the comfort and happiness of the world as it is now used than could ever have been the case when it was the property only of kings.
