Red coral (Ezekiel 27:16).
pearls—literally, "what is frozen." Probably crystal; and Job 28:17 will then be glass.
rubies—UMBREIT translates "pearls" (see Lamentations 4:1; Proverbs 3:15). The Urim and Thummim, the means of consulting God by the twelve stones on the high priest's breastplate, "the stones of the sanctuary" (Lamentations 4:1), have their counterpart in this chapter; the precious stones symbolizing the "light" and "perfection" of the divine wisdom.
