I'm aware that there is disagreement among scholars regarding the colors of stones mentioned in scripture. Possibly some might argue about this quote, but I really like the way this writer thinks.
Having the glory of God: and her light [was] like unto a stone most precious, even like a jasper stone, clear as crystal; Revelation 21:11
"The jasper of the Revelation is not the opaque stone we know by that name. It is later described as a crystal (chapter 21:11). It is probably the diamond, the most brilliant of all the precious jewels. The other stone is blood red, and may really be the ruby. Thus the two together give the idea of glory and sacrifice.
Remembering that many of the first readers of the Revelation were converted Jews, we might ask, what would these stones suggest to them? Surely every instructed Hebrew would instantly recall that they were the first and last stones in the breastplate of the High Priest (Exodus 28:17-20). As these stones bore the names of the tribes of Israel, arranged according to the births of the twelve patriarchs, the one would suggest at once the name of Reuben, “behold a son,” and the other Benjamin, “son of my right hand.” It is Christ enthroned; the Son about to reign in power Who was before the seer’s vision.
