Sapphire Cluster Ringsapphire and diamond engagement ring worn by Diana, Princess of Wales and now by the Duchess of Cambridge, though this sapphire is smaller and the diamonds are larger in relative size. This is a classic design, and it can be spotted accompanying the sapphire set based around pieces given by the Queen's father, King George VI. The ring is not usually mentioned as part of the same set, though, and I don't believe a provenance is known. As this is a basic design, it is also possible multiples exist in the same basic form.
