Miscellanea

  1. Asterism: Asteria, or star stone is a name applied to ornamental stones that exhibit a luminous star when cut en cabochon. The typical asteria is the star-sapphire, generally a bluish-grey corundum, milky or opalescent, with a star of six rays. In red corundum the stellate reflection is less common, and hence the star-ruby occasionally found with the star-sapphire in Ceylon is among the most valued of "fancy stones". When the radiation is shown by yellow corundum, the stone is called star-topaz. Cymophane, the chatoyant chrysoberyl known as cat's eye, may also be asteriated. In all these cases the asterism is due to the reflection of light from twin-lamellae or from fine tubular cavities or thin enclosures definitely arranged in the stone. The astrion of Pliny the Elder is believed to have been a moonstone, since it is described as a colourless stone from India having within it the appearance of a star shining with the light of the moon. Star-stones were formerly regarded with much superstition.
  2. Asterism: In typography, an asterism, from the Greek astēr, is a rarely used and nearly obsolete symbol consisting of three asterisks placed in a triangle. It is used to "indicate minor breaks in text," call attention to a passage, or to separate sub-chapters in a book. It is Unicode character U+2042 ⁂ asterism. In Windows it is possible to use the key combination ALT+8258 to produce the character, but it has very limited support in the default fonts.
