What does Revelation 21:20 mean?
This verse continues the list of jewels found on the foundations of New Jerusalem's wall. They are onyx, carnelian, chrysolite, beryl, topaz, chrysoprase, jacinth, and amethyst. Onyx has layers of black or dark with white. Carnelian is a red jewel. The name, "chrysolite" means gold stone. It includes not only yellow topazes but also other stones of yellow tint. Beryl is a green or blue-green or turquoise gem. Topaz is yellow. Chrysoprase is greenish-yellow. Jacinth is a smoky blue, and amethyst is a violet-colored gem. Many of these gems were also included in the high priest's breastplate (Exodus 28:17–21).It is not necessary to assume that all these gems came from mines. God created everything in the beginning, including the precious stones that miners extract from mines. Undoubtedly, He will create the jewels that adorn the foundations of New Jerusalem's walls. It is impossible to grasp the dazzling beauty that radiates from the wall's foundations, but the display speaks volumes about God's glorious character and creative work in building New Jerusalem.
