Revelation 21:17-21

And he measured its wall, 144 cubits, by human measurements, which are also angelic measurements.

The material of the wall was jasper; and the city was pure gold, like clear glass.

The foundation stones of the city wall were decorated with every kind of precious stone. The first foundation stone was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;

the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst.

And the twelve gates were twelve pearls; each one of the gates was a single pearl. And the street of the city was pure gold, like transparent glass.
