 agate
      n : an impure form of quartz consisting of banded chalcedony;
          used as a gemstone and for making mortars and pestles


 Agate
    (Heb. shebo), a precious stone in the breast-plate of the high
    priest (Ex. 28:19; 39:12), the second in the third row. This may
    be the agate properly so called, a semi-transparent crystallized
    quartz, probably brought from Sheba, whence its name. In Isa.
    54:12 and Ezek. 27:16, this word is the rendering of the Hebrew
    cadcod, which means "ruddy," and denotes a variety of minutely
    crystalline silica more or less in bands of different tints.

      This word is from the Greek name of a stone found in the river
    Achates in Sicily.
