In 1927, Helene's elder son, Amedeo, married Anne of Orleans (Helene's niece and, therefore, Amedeo's first cousin). Helene offered the diamond and emerald necklace to Anne as a wedding present. Amedeo and Anne were Margherita's parents, and she eventually inherited the necklace from her mother. She also wore it during her mother's lifetime; she was even featured wearing the necklace on the cover of Paris Match.
