Crystal

kris´tal : In English Versions of the Bible the word is probably intended to signify rock-crystal, crystallized quartz. This the Greeks called κρύσταλλος , krústallos , "ice," believing it to have been formed from water by intense cold. Thus in Revelation 4:6; Revelation 21:11; Revelation 22:1 , either "crystal" (EV) or "ice" (Greek, krustallos ) suits the context. The word rendered "crystal" in Ezekiel 1:22 ( קרח , ḳeraḥ ) is ambiguous in precisely the same way (the Revised Version, margin "ice"). In Job 28:17 the context favors the King James Version "crystal," rather than the Revised Version (British and American) "glass" ( זכוּכית , zekhūkhı̄th ). Finally, in Job 28:18 the Revised Version (British and American) reads "crystal" for the King James Version "pearls" (Hebrew gābhı̄sh  ; the weight of evidence favors the Revised Version (British and American) in spite of the parallelism suggested by the King James Version).
