Today’s jewel challenge features a member of two reigning royal families: Princess Margaretha of Liechtenstein, who was born a princess of Luxembourg and married Prince Nikolaus of Liechenstein (also pictured above). Can you identify the jewels that Margaretha wore during the grand ducal family’s 2007 state visit to Belgium?

(As an extra Luxembourg/Liechtenstein-related treat today, hop over to Lux-arazzi to read an interview I did recently about royal blogging and royal jewels!)
