In this way crystals having the same form, hardness, color, specific gravity, composition, and effect on light as the true ruby, the cymophane, and other mineral bodies were prepared, and were in fact identical with them.

Cymophane, or chatoyant chrysoberyl, may also be asteriated.

The cymophane is mostly from the gem-gravels of Ceylon.

He would often spend a whole day settling and resettling in their cases the various stones that he had collected, such as the olive-green chrysoberyl that turns red by lamp-light, the cymophane with its wire-like line of silver, the pistachio-coloured peridot, rose-pink and wine-yellow topazes, carbuncles of fiery scarlet with tremulous four-rayed stars, flame-red cinnamon-stones, orange and violet spinels, and amethysts with their alternate layers of ruby and sapphire.

Another important variety is that of the chrysoberyl called "cymophane."
