Revelation 21:18-21

The wall was made of jasper, and the city was made of pure gold, as pure as glass. The foundation stones of the city walls were decorated with every kind of jewel. The first foundation was jasper, the second was sapphire, the third was chalcedony, the fourth was emerald, the fifth was onyx, the sixth was carnelian, the seventh was chrysolite, the eighth was beryl, the ninth was topaz, the tenth was chrysoprase, the eleventh was jacinth, and the twelfth was amethyst. The twelve gates were twelve pearls, each gate having been made from a single pearl. And the street of the city was made of pure gold as clear as glass.
