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.

תרשיש, a pellucid gem of a bluish green colour, whence it is called by the lapidaries, _aqua marina_. Its Hebrew name is a word also for the same reason given to the sea, Psalm xlviii, 7. It is found in the East Indies, Peru, Siberia, and Tartary.
