Revelation 21:18-21

The city was pure gold, clear as crystal, and its wall was made of jasper. The twelve foundations of the wall were adorned with every kind of precious stone—the first was jasper, the second sapphire, the third agate, the fourth emerald, the fifth onyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh turquoise, and the twelfth amethyst. The twelve gates are twelve pearls—each gate made of one pearl. And the street of the city was pure gold, clear as crystal.
