The Nizam of Hyderabad Necklace
The duchess doesn't normally wear that much jewelry, but earlier this year, the queen reportedly asked that Kate be given more access to the royal jewels to give her a "princess-y" makeover. Enter the Nizam of Hyderabad necklace, which Kate wore during a visit to the National Portrait Gallery (where she serves as a patron) in February. The necklace was given to the queen by (who else?) the Nizam of Hyderabad, as a wedding present. He told the queen to pick out anything that she wanted from Cartier, and she selected this glittering number, which features a chain of 38 diamonds plus a center piece of 13 emerald-cut diamonds.
