a precious stone, forming one of the foundations of the walls of the new Jerusalem. (Revelation 21:20) Called hyacinth in the Revised Version. This is simply a different English rendering of the same Greek original. It is probably identical with the lighure of (Exodus 28:19) The Jacinth or hyacinth is a red variety of zircon, which is found in square prisms of a white, gray, red, reddish-brown, yellow or pale-green color. The expression in (Revelation 9:17) "of jacinth," is descriptive simply of a dark-purple color.
