A precious stone of various colors, as green, purple, etc., often clouded with white, and beautifully striped with red or yellow, ; ; 21:11.\par
(ἴασπις, from Assyr. aspû)
The king on the heavenly throne is like a jasper stone (); the luminary of the New Jerusalem is like a stone most precious, as it were a jasper stone, clear as crystal (21:11); and the first foundation stone of the wall is a jasper. The jasper of mineralogy is an opaque, compact variety of quartz, variously coloured-red, brown, yellow, or green. As this stone does not answer the description ‘clear as crystal,’ some think that the diamond is meant (Smith’s Dict. of the Bible s.v.), while others suggest the opal (Encyclopaedia Biblica s.v.). The ἴασπις of the Septuagint () may have been the dark green jasper, which was known to the Egyptians and the early Greeks.
James Strahan.
Rev 4:3 (c) Probably a very valuable stone, translucent or transparent, typical of the preciousness of our GOD in whom there is no flaw, defilement, evil, nor spot of any kind. He was beautiful, precious, valuable and attractive. (See also Rev 21:11).
Last of the gems in the high priest's breast-plate (Exo 28:20), probably the green jasper. In Rev 21:19 it is first of New Jerusalem's foundations. It represents watery crystalline brightness, symbol of purity: Rev 21:11, *her light was like unto a stone most precious, even like a jasper stone, clear as crystal.* *He that sat upon the throne (Rev 4:3) was to look upon like a jasper.* Ebrard thinks the diamond is meant. The common jasper has various wavy colors, somewhat transparent. The king of Tyre (Eze 28:13) has the jasper with eight other of the high-priest's 12 precious stones, as type of antichrist who usurps Christ's high-priesthood combined with kingship (Zec 6:13).
Our word Jasper is plainly from the Greek jaspis, which comes from the Hebrew word yashpeh. Jasper is a species of the quartz family, and embraces a great many varieties. The brown Egyptian variety was perhaps the one selected for the breastplate of the high-priest (; ). The brown is of various shades, disposed in concentric stripes. It occurs loose in the sands of Egypt, and is cut into ornaments.
Jasper. A precious stone frequently noticed in Scripture. It was the last of the twelve inserted in the high priest's breastplate, ; , and the first of the twelve used in the foundations of the new Jerusalem. .
The characteristics of the stone, as far as they are specified in Scripture, , are that it *was most precious,* and *like crystal;* we may also infer from , that it was a stone of brilliant and transparent light. The stone which we name *jasper* does not accord with this description. There can be no doubt that the diamond would more adequately answer to the description in the book of Revelation.
Jasper has the formulae SiO2.
It has a relative hardness of 7.
It is a form of quartz usually coloured red from inclusions of hematite.

The Greek and Latin name, jaspis, as well as the English jasper, is plainly derived from the Hebrew, and leaves little room to doubt what species of gem is meant by the original word. The jasper is usually defined, a hard stone, of a bright, beautiful, green colour; sometimes clouded with white, and spotted with red or yellow.
(n.) An opaque, impure variety of quartz, of red, yellow, and other dull colors, breaking with a smooth surface.
