Disclosed is a chrysoberyl cat's-eye synthetic single crystal, which comprises aluminum oxide and beryllium oxide as main component, and 0.005 to 1.050% by weight, based on the total crystal, of at least one member selected from oxides of iron, cerium, vanadium, cobalt, tungsten, chromium, nickel and manganese and 0.005 to 2.0% by weight, based on the total crystal, of at least one member selected from oxides of titanium, tin, zirconium and germanium. This synthetic single crystal is comparable to natural cat's-eye in the physical properties, color tone and chatoyancy effect. |
