  Garnet \Gar"net\, n. [OE. gernet, grenat, OF. grenet,grenat, F.
     grenat, LL. granatus, fr. L. granatum pomegranate, granatus
     having many grains or seeds, fr. granum grain, seed. So
     called from its resemblance in color and shape to the grains
     or seeds of the pomegranate. See Grain, and cf. Grenade,
     Pomegranate.] (Min.)
     A mineral having many varieties differing in color and in
     their constituents, but with the same crystallization
     (isometric), and conforming to the same general chemical
     formula. The commonest color is red, the luster is vitreous,
     and the hardness greater than that of quartz. The
     dodecahedron and trapezohedron are the common forms.
     [1913 Webster]
  
     Note: There are also white, green, yellow, brown, and black
           varieties. The garnet is a silicate, the bases being
           aluminia lime (grossularite, essonite, or cinnamon
           stone), or aluminia magnesia (pyrope), or aluminia iron
           (almandine), or aluminia manganese (spessartite), or
           iron lime (common garnet, melanite, allochroite), or
           chromium lime (ouvarovite, color emerald green). The
           transparent red varieties are used as gems. The garnet
           was, in part, the carbuncle of the ancients. Garnet is
           a very common mineral in gneiss and mica slate.
           [1913 Webster]
  
     Garnet berry (Bot.), the red currant; -- so called from its
        transparent red color.
  
     Garnet brown (Chem.), an artificial dyestuff, produced as
        an explosive brown crystalline substance with a green or
        golden luster. It consists of the potassium salt of a
        complex cyanogen derivative of picric acid.
        [1913 Webster]
