Amongst the Spaniards it was usual at one time for conjurers and jugglers especially to wear tight-fitting coral-coloured costumes. Good specimens of coral are greatly esteemed by dancers. It is especially a luck gem of the ballet, the sign Pisces of the Zodiac, under which all corals are placed—ruling the feet. CORUNDUM. Also written at earlier periods as coriundum, corundon, corindon. (See under Ruby, Sapphire.) CORDIERITE. See IOLITE. CROCIDOLITE. Also written Krokydolite, krocidolite. This stone was named in the year 1831, from the Greek KROKIS, a variation of KROKUS, the nap of woollen cloth, and LITHOS, a stone. It is well described as an asbestiform variety of hornblend of indigo-blue, leek-green or golden-brown colour—the latter variety being also known as Tiger’s Eye. When cut en cabochon this stone has a fine chatoyant effect. There is little doubt that the ancients knew of this stone of the asbestos family under the zodiacal Gemini. It was regarded as a fortunate stone for people of literary or mercurial tendencies, and as a nerve and lung soother. Held against the temple when the Moon is passing through the sign Gemini, in good aspect to Mercury, it would assist thought and mental speculation. CRYSTAL
