CHAPTER XIV.
THE GARNET, CARBUNCLE, AND CINNAMON STONE.
NDER the general name of Garnet, the min­eralogist includes a number of stones which present a great variety of colour, ranging from the lightest cinnamon, through all shades of red and crimson, and even to various tints of green. Be­tween these diverse minerals the chief bonds of association are to be found in their crystallographic relations, and their constancy of chemical type. On glancing at the various analyses of different Garnets, one might fail to recognize their relationship; but the chemist is aware that these changes of composition take place according to cer­tain definite laws, without violating the general type on which they are constructed. Their specific gravity, and even their hardness, are subject to great variations, corres­ponding to their differences of composition. They all belong to the isometric or cubic system, and are conse­quently monochroic.
The Garnet was a great favourite with the Ancients, and antique Garnets have often been found in Roman ruins. In former days it was very frequently engraved, and beautiful specimens are now to be seen in Paris, Turin, Rome, and St. Petersburg. The small degree of hardness possessed by this stone renders engraving on it compara­tively easy.
The word Garnet probably owes its origin to the similarity of the colour of this stone to that of the blossom
