(originally appeared in the New York Times, 16 Aug 1891)
The magnificent diamond tiara and necklace  which the Duchess of Aosta  wore when she appeared in full dress on her recent visit to England are the famous jewels which the Emperor Napoleon  gave to Princess Clotilde  in 1859 on her marriage, and they were worth a good fortune.
