The catseye is a chalcedonic quartz, translucent, of various colours—yellow-green, yellow-brown, hyacinth-red, grey, green-grey, etc. It is of a peculiar opalescence, resembling the eye of a cat, when cut en cabochon, an effect produced by amianthoid asbestos filaments which run parallel through the stone. The virtues ascribed to the catseye are many. It was said to put colour into pale faces, to give pleasure to the mind, to relieve the soul of melancholy, to cure chronic disorders and wasting diseases, and to keep the wearer from financial distress and ruin. It is said to have been successfully employed in relieving croup and asthma. Pressed on to the forehead between the eyes it aided thought and helped foresight. Carried by those with Capricorn rising in the horoscope, or with the Sun, Jupiter or Venus in Capricorn, it is credited with especial value as a charm for success in speculative ventures. Enwrapped in women’s hair, it was employed as a birth charm, and if calcined and applied to wounds, said Rabbi Ben Adoulah, it healed them. Further, it cured inflammations of the eyes, if lightly rubbed on the closed lids. To dream of a catseye was said to warn of treachery. It was the Eye of Belus in old Assyria, and a talisman which made the wearer invisible to his enemies. Old Indian masters advise that the specimen worn be as perfect as possible, saying that bad stones should not be worn at all. The Catseye is attached to the sign Capricorn. CEYLONITE. (See SPINEL.) CHALCEDONY “_With lustre fair is the Calcedon graced._” MARBODUS. The chalcedony obtains its name from Chalkedon in Asia Minor, and appears written as calcedony, calsydoyne, calcidoine, chalcedun, calcideny, chalcidonye, calcedon, calchedonie. This stone includes a number of varieties such as carnelian, sard, agate, catseye, prase, plasma, heliotrope, chrysoprase, moss agate, onyx, sardonyx, hornstone or Chert, and flint. Chalcedony is classed under the great Silica family. It is translucent, waxy, white, pale grey, light brown or bluish. The Blue Chalcedony is identified with the ancient Sapphirine—a stone confused with our sapphire. Mr. King says that the “finest Persian cylinder known, engraved with the usual type of the King fighting with the lion, was formed out of this variety: the signet doubtless that once graced the wrist of some Darius or Artaxerxes of the latter days of the Persian monarchy.”
