> examine ruby
This large ruby would fit nicely into your hand. It has been cut by some very
skilled craftsman and its sides are perfectly symmetrical. The ruby glows in a
mysterious red light; a closer look at the inside reveals a million small
rays and sparks of red, which are reflected and broken more often than there
are glowing sparks in a great fire.
