Chrysoprase (χρυσό π ρασος, from χρυσός, ‘gold,’ and πράσον, ‘a leek’)
This stone is the tenth foundation of the wall of the New Jerusalem (Revelation 21:20). The name is now applied to an apple-green variety of chalcedony or hornstone, prized in jewellery and sometimes used for mural decorations. but this chalcedony was probably unknown to the ancients, and the χρυσό π ρασος of the Greeks was ‘not improbably our chrysoberyl’ (EBr [Note: Br EncyclopAEdia Britannica.] 11 vi. 321). The word is not found in either of the LXX [Note: XX Septuagint.] lists of precious stones (Exodus 28:17-20, Ezekiel 28:13) with which the writer of Rev. was familiar.
