Jasper <1,,2393, iaspis>
a Phoenician word (cp. Heb. yash'pheh, e.g., Exo 28:20, Exo 39:16), seems to have denoted a translucent stone of various colors, especially that of fire, Rev 4:3, Rev 21:11, Rev 1:21-19. The sardius and the jasper, of similar color, were the first and last stones on the breastplate of the high priest, Exo 28:17, Exo 28:20.
