The 12 gates were made from 12 pearls; each gate was made out of a single pearl. The main street of the city was made out of gold that was as pure as clear glass.
The foundations of the city walls were decorated with every kind of jewel. The first foundation was made out of jasper. The second was made out of sapphire. The third was made out of agate. The fourth was made out of emerald.
In front of the throne there was also something that looked like a sea of glass, clear as crystal. In the inner circle, around the throne, were four living creatures. They were covered with eyes in front and in back.
