cargo such as gold, silver, precious stones, pearls, fine linen, purple cloth, silk, scarlet cloth, all sorts of things made of citron wood, all sorts of objects made of ivory, all sorts of things made of expensive wood, bronze, iron and marble,

saying, "Woe, woe, O great city -- dressed in fine linen, purple and scarlet clothing, and adorned with gold, precious stones, and pearls --

And the twelve gates are twelve pearls -- each one of the gates is made from just one pearl! The main street of the city is pure gold, like transparent glass.
