So these are the 12 stones that are the building materials of the new Jerusalem (mentioned in Revelation 21:18)
and of the 28 or so precious and semi-precious stones in the world, these 12 are anisotropic, meaning that under pure light, they reflect all the colors of the rainbow beautifully.
Interestingly, neither diamond, rubies or garnets are mentioned. Turns out, it’s because they are isotropic, when Pure light passes trough them, there is no beauty at all.
So I imagine an entire city built out of these materials looking something like the rainbow road in the movie, Thor.
So watch this, forget what Thor and Loki are doing for a sec, and check out that Byfrost road thing they’re on. Looks like movie magic but, according to Revelation, there’s going to be a street and a whole city very similar to that…but better! It blows my mind.
Rev 21:21 “…and the street of the city was pure gold, like transparent glass.”
