Dipping into the jewelry box of your grandmother-in-law is elevated to say the least when you're a member of Britain's royal family.

Kate, the Duchess of Cambridge, chose to wear earrings owned by her husband's grandmother, Queen Elizabeth II, for a reception Tuesday that saw her mingling with world leaders.
