2 Bible Verses about Gems

As for the foundation-stones of the city wall, which were beautified with various kinds of precious stones, the first was jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth sardius, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, the twelfth amethyst. And the twelve gates were twelve pearls; each of them consisting of a single pearl. And the main street of the city was made of pure gold, resembling transparent glass.

For no one can lay any other foundation in addition to that which is already laid, namely Jesus Christ. And whether the building which any one is erecting on that foundation be of gold or silver or costly stones, of timber or hay or straw-- the true character of each individual's work will become manifest. For the day of Christ will disclose it, because that day is soon to come upon us clothed in fire, and as for the quality of every one's work-- the fire is the thing which will test it.
