William de Lillo was born in Belgium and moved to NYC in the 1950s.  He worked with Tiffany's, Cartier, Miriam Haskell and Harry Winston before meeting his partner Robert Clark at Miriam Haskell. Together they started William De Lillo Ltd in 1969. The jewelry was designed to be unisex, with the idea that necklaces should replace ties. The collections were very limited and only sold at high end stores. They closed the company in 1976, when William and Robert moved to France, where they then went on to collaborate with couture fashion houses like Chanel, Yves Saint Laurent, Nina Ricci and Schiaparelli. Some of their clients included the Duchess of Windsor and Elizabeth Taylor.
