Settings of stones. These were similar to those of the two shoulder stones—i.e. of filagree or cloisonne work—as appears from Exodus 39:13. The first row of the stones is said to have been composed of a sardius, or sard, a topaz, and a carbuncle.
Of these names the first only would seem to be tolerably certain. The second cannot be right, since the topaz was too hard a stone to be engraved by the ancient engravers. We may conjecture that the chrysolite, a pale stone not unlike the topaz, but far less hard, was the Genesis intended.
The "carbuncle" is also thought to be wrong; and the "beryl" is suggested by some; by others "a sort of precious corundum." Emerald, to which the "smaragdus" of the LXX. and Josephus would seem to point, cannot be right, since that stone is fully as hard as the topaz.
