Sisters in Style: The Fashion Brands Kate Middleton and Meghan Markle Love

Cartier is the royal jewelry house, which has significant meaning for both Kate and Meghan. Kate has borrowed assorted Cartier pieces from the royal collection, including the Nizam of Hyderabad necklace and halo tiara that she wore on her wedding day, as well as her own pieces, including her watch and a few necklaces like the striking piece she wore to the National Portrait Gallery for an Olympics exhibition in 2012.
