Topaz
Heb. pitdah (Ezek. 28:13; Rev. 21:20), a golden yellow or "green" stone brought from Cush or Ethiopia (Job 28:19). It was the second stone in the first row in the breastplate of the high priest, and had the name of Simeon inscribed on it (Ex. 28:17). It is probably the chrysolite of the moderns.
