BERYL
(A) Heb. “tarshish”; precious stone undoubtedly related to the place of origin of the first stone of the fourth row of the breastplate (Ex. 28:20; 39:13; Song 5:14; Ezek. 1:16; 10:9; 28:13; Dan. 10:6).
None of the passages give any indication of the color of this stone. There are some commentators who translate the “tarshish” of Cnt. 5:14 for topaz and “tarshish” of Ex. 28:20 by chalcedony. In the LXX it is translated as chrysolite in Ex. 28:20; 39:13; Ez. 28:13, and as “anthrax,” which is translated “carbuncle,” in Ez. 10:9.
(B) The term gr. “beryllos” of Rev. 21:20 is translated as beryl, to designate the eighth foundation of the New Jerusalem. Beryl is a rock mineral, formed especially by silica and aluminum; It is usually green or bluish-green in color; It also appears in blue, pink, yellow, or aquamarine varieties; It is related to the emerald.
