Tiffany & Co. jewelry is all over the place in this Kenneth Branagh remake of the Agatha Christie story. Linnet Ridgeway Doyle ( Gal Gadot) receives a 128.54 carat yellow diamond necklace as a wedding present from her husband, Simon Doyle (Armie Hammer); Euphemia ( Annette Bening) sports gold and diamond jewels from the Jean Schlumberger line, and Jacqueline De Bellefort (Emma Mackey) wears jewelry from the Victoria collection.
