Sapphires are found in alluvial soil near rocks and embedded in gneiss. The ancients distinguished two kinds: 1. The real, of transparent blue: 2. That improperly so called, opaque, with gold spots; that is, lapis lazuli. To the latter, looking like gold dust, Umbreit refers “dust of gold.” English Version better, “The stones of the earth are, etc., and the clods of it (Vulgate) are gold”; the parallel clauses are thus neater.
