* a ligure.
   {Leshem,} the ligure, the same as the jacinth, or hyacinth, a
   precious stone of a deep red, with a considerable tinge of
   yellow.  Theophrastus and Pliny say it resembles the
   carbuncle, of a brightness sparkling like fire.

 * an agate.
   {Shevo,} the agate, a semi-pellucid compound gem, formed of
   different simple minerals, as chalcedony, cornelian, jasper.
   horn-stone, quartz, amethyst, opal, etc.; joined irregularly
   or in layers.  It is of a white, reddish, yellowish, or
   greenish ground; and so variously figured in its substance as
   to represent plants, trees, animals, and other objects.

 * an amethyst.
   {Achlamah,} an amethyst, a transparent gem, composed of a
   strong blue and deep red; and according as either prevails,
   affording different tinges of purple, sometimes approaching
   to violet, and sometimes even fading to a pale rose colour.
