(Heb. yashpheh, "glittering"), a gem of various colours, one of the twelve inserted in the high priest's breast-plate ( Exodus 28:20 ). It is named in the building of the New Jerusalem ( Revelation 21:18 Revelation 21:19 ). It was "most precious," "clear as crystal" ( 21:11 ). It was emblematic of the glory of God ( 4:3 ).
a precious stone frequently noticed in Scripture. It was the last of the twelve inserted in the high priests breastplate, ( Exodus 28:20 ; 39:13 ) and the first of the twelve used in the foundations of the new Jerusalem. ( Revelation 21:19 ) The characteristics of the stone as far as they are specified in Scripture, ( Revelation 21:11 ) are that it "was most precious," and "like crystal;" we may also infer from ( Revelation 4:3 ) that it was a stone of brilliant and transparent light. The stone which we name "jasper" does not accord with this description. There can be no doubt that the diamond would more adequately answer to the description in the book of Revelation.
