The Talisman of Charlemagne, c. 768-814. Two large cabochon sapphires - one oval, one square - enclose holy relics (what are supposed to be a remnant of the Holy Cross and a small piece of the Virgin's hair, visible only when looking through the oval sapphire at the front of the medallion.) The other gemstones are garnets, emeralds, and pearls.
