Revelation 21:14-20

14The wall of the city had twelve foundation stones, and on them were written the names of the twelve apostles of the Lamb.

15The angel who talked to me held in his hand a gold measuring stick to measure the city, its gates, and its wall.

16When he measured it, he found it was a square, as wide as it was long. In fact, its length and width and height were each 1,400 miles.

17Then he measured the walls and found them to be 216 feet thick (according to the human standard used by the angel).

18The wall was made of jasper, and the city was pure gold, as clear as glass.

19The wall of the city was built on foundation stones inlaid with twelve precious stones: the first was jasper, the second sapphire, the third agate, the fourth emerald,

20the fifth onyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, the twelfth amethyst.
