The Collaborative International Dictionary of English v.0.48:

Luster \Lus"ter\, Lustre \Lus"tre\, n. [F. lustre; cf. It.
   lustro; both fr. L. lustrare to purify, go about (like the
   priests at the lustral sacrifice), traverse, survey,
   illuminate, fr. lustrum a purificatory sacrifice; perh. akin
   to E. loose. But lustrare to illuminate is perhaps a
   different word, and akin to L. lucere to be light or clear,
   to shine. See Lucid, and cf. Illustrious, Lustrum.]
   [1913 Webster]
   1. Brilliancy; splendor; brightness; glitter.
      [1913 Webster]

            The right mark and very true luster of the diamond.
                                                  --Sir T. More.
      [1913 Webster]

            The scorching sun was mounted high,
            In all its luster, to the noonday sky. --Addison.
      [1913 Webster]

   Note: There is a tendency to limit the use of luster, in this
         sense, to the brightness of things which do not shine
         with their own light, or at least do not blaze or glow
         with heat. One speaks of the luster of a diamond, or of
         silk, or even of the stars, but not often now of the
         luster of the sun, a coal of fire, or the like.
         [1913 Webster]

   2. Renown; splendor; distinction; glory.

                                                  Wotton.
      [1913 Webster]

   3. A candlestick, chandelier, girandole, or the like,
      generally of an ornamental character. --Pope.
      [1913 Webster]

   4. (Min.) The appearance of the surface of a mineral as
      affected by, or dependent upon, peculiarities of its
      reflecting qualities.
      [1913 Webster]

   Note: The principal kinds of luster recognized are: metallic,
         adamantine, vitreous, resinous, greasy, pearly, and
         silky. With respect to intensity, luster is
         characterized as splendent, shining, glistening,
         glimmering, and dull.
         [1913 Webster]

   5. A substance which imparts luster to a surface, as graphite
      and some of the glazes.
