ber·yl /ˈbɛrəl/
 綠玉石,綠寶石
 Ber·yl n.  Min. A mineral of great hardness, and, when transparent, of much beauty. It occurs in hexagonal prisms, commonly of a green or bluish green color, but also yellow, pink, and white. It is a silicate of aluminum and beryllium. The aquamarine is a transparent, sea-green variety used as a gem. The emerald is another variety highly prized in jewelry, and distinguished by its deep color, which is probably due to the presence of a little oxide of chromium.

 Beryl
    the rendering in the Authorized Version of the Hebrew word
    _tarshish_, a precious stone; probably so called as being
    brought from Tarshish. It was one of the stones on the
    breastplate of the high priest (Ex. 28:20; R.V. marg.,
    "chalcedony;" 39:13). The colour of the wheels in Ezekiel's
    vision was as the colour of a beryl stone (1:16; 10:9; R.V.,
    "stone of Tarshish"). It is mentioned in Cant. 5:14; Dan. 10:6;
    Rev. 21:20. In Ezek. 28:13 the LXX. render the word by
    "chrysolite," which the Jewish historian Josephus regards as its
    proper translation. This also is the rendering given in the
    Authorized Version in the margin. That was a gold-coloured gem,
    the topaz of ancient authors.
