Revelation 21:19,20

And the foundations of the wall That is, the lower parts of it; were garnished with all manner of precious stones Were inlaid quite round, and beautified with a great variety of them; or were beautifully formed of them. The precious stones on the high-priest's breast-plate of judgment were a proper emblem to express the happiness of God's church in his presence, and in the blessing of his protection. The like ornaments on the foundation of the walls of this city may express the perfect glory and happiness of all the inhabitants of it, from the most glorious presence and protection of God. The colours of these are remarkably mixed. A jasper A precious stone as hard as marble, and of various colours, as of green, yellow, red, violet; a sapphire Of a sky-blue, speckled with gold; a chalcedony Or carbuncle, an elegant gem, whose colour is deep red: with an admixture of scarlet; an emerald Of a bright green; a sardonyx Red, streaked with white; a sardius Or sardine -stone, of a deep red; a chrysolite Of a gold colour, as the word signifies; a beryl Sea- green; a topaz A mixture of green and yellow; a chrysoprasus A beautiful mixture of gold and green; a jacinth Of a red purple; an amethyst A violet purple. And the twelve gates were twelve pearls Each one being a pearl, entire and undivided, with all their beautiful pillars, arches, mouldings, and cornices. And the street was pure gold And yet transparent, reflecting the light that shone upon it with a lustre equal to that which is the most highly polished.
