one of the gems used in the high priests breastplate, ( Exodus 28:17 ; 39:10 ; Ezekiel 28:13 ) one of the foundations also of the New Jerusalem, in St. Johns description of the city. ( Revelation 21:20 ) The topaz of the ancient Greeks and Romans is generally allowed to be our chrysolite, while their chrysolite is our topaz.
