The eight items of stolen jewellery included a tiara and earrings from the set of Queen Marie-Amélie and Queen Hortense, of the early 19th century. Christopher Marinello, founder of Art Recovery International, which tracks stolen art, said museum heists were on the rise across Europe and further afield. "If you have jewels or gold in your collections, you need to be worried."
