onyx

A type of quartz with varicolored bands. Onyx was found in the land of Havilah, according to (Gen 2:12), and ranked with gold of Ophir (Job 28:16). It heads the list of precious stones provided by David for the Temple (1Chr 29:2). The two stones on the shoulders of the high priest’s ephod were onyx (Exod 28:9-12), and so was the eleventh stone on his breastpiece (Exod 28:20). Onyx also appears in (Rev 21:20) as one of the twelve jewels adorning the wall of the heavenly Jerusalem.
