If anyone were to ask me where I could find a reference to gems and jewels in the Bible I would automatically turn to Revelation. Near the very end of the Bible Revelation shows that a Holy City is coming down to earth and the beauty is undeniably glowing and sparkling beyond my wildest imagination.
From Revelation 21: 18-21 (NIV) "The wall was made of jasper, and the city of pure gold, as pure as glass. The foundations of the city walls were decorated with every kind of precious stone. The first foundation was jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, and the twelfth amethyst. The twelve gates were twelve pearls, each gate made of a single pearl. The great street of the city was of pure gold, like transparent glass."
