Charles Ellicott Commentary Revelation 21:11

"having the glory of God: her light was like unto a stone most precious, as it were a jasper stone, clear as crystal:" — Revelation 21:11 (ASV)

Having the glory of God . . .—The glory of God is the glorious presence of God, the true Shechinah, of which we have read before (Revelation 15:8, and see Revelation 21:23). The light of the city is described: And her light (or, brightness: it is the light which she gives; the same word is used as in the Septuagint, Genesis 1:17, for the heavenly bodies) is like a stone most precious, as if it were a jasper stone crystallizing.

On the meaning and appearance of this stone, see Note on Revelation 4:3. It is in all probability a stone transparent and clear as crystal, but retaining the greenish hue belonging to the jasper. The general brightness of the city was lustrous as the diamond but shot with the green tint of the emerald bow which swept the throne .
