The crown includes several famous jewels. The cross at the top is set with a stone known as St. Edward's Sapphire, a sapphire taken from the ring (or possibly coronet) of Edward the Confessor. The Black Prince's Ruby (actually a spinel) is set on the front cross pattée; the famous Cullinan II, or Lesser Star of Africa, is set on the front; and the back band contains the Stuart Sapphire. The crown also contains Queen Elizabeth’s Pearls.
