Chalcedony


"Mentioned only in Rev. 21:19, as one of the precious stones in" the foundation of the New Jerusalem. The name of this stone is "derived from Chalcedon, where it is said to have been first" discovered. In modern mineralogy this is the name of an agate-like quartz of a bluish colour. Pliny so names the Indian ruby. The mineral intended in Revelation is probably the Hebrew "nophekh, translated "emerald" (Ex. 28:18; 39:11; Ezek. 27:16;" "28:13). It is rendered "anthrax" in the LXX., and "carbunculus" in the Vulgate. (See [109]CARBUNCLE.)
