Beautiful sterling silver bypass ring band with two real stones, the Urim (white stone) and the Thummim (black stone). History: Urim and Thummim Exodus 28:30 "And thou shalt put in the breastplate of judgment the Urim and Thummim; they shall be upon Aaron's heart when he goeth in before the Lord." The Urim and Thummim was God's way of answering His people. Urim means light and Thummim means darkness/truth. A very beautiful ring.
