It is found in rolled pebbles in Brazil and Ceylon; in fine crystals (variety alexandrite) in the Ural; and in granite at Haddam, Connecticut, and elsewhere in the United States. It is next to the sapphire in hardness, and some varieties are employed in jewelry, the kind called cat's-eye, which presents an opalescent play of light, being especially admired. The variety alexandrite, having an emerald-green color by reflected and a columbine-red by transmitted light, is also prized as a gem. Also called cymophane.
