3 that looked like a jasper stone and a sardius. There was a rainbow around the throne, like an emerald to look at.
Jasper and Sardius stone in appearance – a red colour. In Ezek 1:27, His appearance is described as either “glowing metal” NASB, or “as the colour of Amber” (orange-red) NKJV. John repeats the word “appearance” as did Ezekiel, emphasizing this as a vision. For as John said, “no one has seen God at any time” (1 John 4:12).
there was a rainbow around the throne – see also Ezek 1:27-28. In Rev 10:1, the Spirit of Christ, as the Angel of God, appears with the rainbow over His head, signifying that He was also “the image of the invisible God,” in this passage.
