Revelation 21:21

21 The twelve gates were twelve pearls; each gate was made from a single pearl. The street of the city was of pure gold, transparent as glass.

Revelation 21:21 In-Context

19 The foundation stones of the city wall were adorned with all kinds of precious stones. The first foundation stone was jasper, the second sapphire, the third agate, the fourth emerald,
20 the fifth onyx, the sixth carnelian, the seventh yellow quartz, the eighth beryl, the ninth topaz, the tenth chalcedony, the eleventh turquoise, the twelfth amethyst.
21 The twelve gates were twelve pearls; each gate was made from a single pearl. The street of the city was of pure gold, transparent as glass.
22 I did not see a temple in the city, because its temple is the Lord God Almighty and the Lamb.
23 The city has no need of the sun or the moon to shine on it, because the glory of God shines on it, and the Lamb is its lamp.
