The foundation of the city's wall was decorated with all kinds of precious stones [Note: Not all of the following stones listed can be accurately identified today]. The first foundation stone was jasper [i.e., a bluish-colored stone]; the second was sapphire; the third was chalcedony [i.e., a translucent quartz of pale blue or gray]; the fourth was emerald; the fifth was sardonyx [i.e., an orange-colored stone similar to chalcedony]; the sixth was sardius [i.e., a reddish-colored stone also called carnelian]; the seventh was chrysolite [i.e., a yellowish- or greenish-colored stone]; the eighth was beryl [i.e., a stone of bluish-green color]; the ninth was topaz [i.e., a yellow or bluish-yellow stone]; the tenth was chrysoprase [i.e., a stone of greenish-gold color]; the eleventh was jacinth [i.e., a stone of purple or reddish-blue color]; the twelfth was amethyst [i.e., a purple- or violet-colored stone]. And the twelve gates were made of twelve pearls, with each gate being made of a single pearl. And the street of the city was made of pure gold, as transparent as glass.

For no one can lay [any] other foundation than the one which [God] has [already] laid, which is Jesus Christ. But if anyone [i.e., a preacher or soul winner] builds on this foundation with gold, silver, expensive building stones, wood, grass, or straw, [the quality of] each person's work will become evident [i.e., for what is it made of]. For the [judgment] day will expose his workmanship. And it will be revealed by the fire [of judgment], which will test the quality of a person's workmanship [i.e., the faithfulness of his converts].
