It has been supposed to designate the same stone as the ligure (Hebrew leshem) mentioned in Exodus 28:19 as the first stone of the third row in the high priest's breast-plate, the Hoshen or choshen. In Revelation 9:17, the word is simply descriptive of colour. In Revelation 21:19-20, it is mentioned as one of the foundational stones of the New Jerusalem.
