It is also known as "the star sapphire" and "the asteriated sapphire."

This is not the same variety as the "asteriated," or "cat's eye" or "lynx eye" mentioned above.

There are certain stones and other minerals which, owing to their possession of numerous microscopically fine cavities, of a globular or tubular shape, have the appearance of "rays" or "stars," and these are called "asteriated."
