<P> London - based jewelers Asprey & Garrard used cubic zirconias set in white gold to create an Edwardian - style necklace to be used as a prop in the film . Asprey & Garrard produced and designed the necklaces : the result was three different and unique designs . Two of their designs were used in the film while the other went unused until after the film had been released . The three necklaces are commonly known as the original prop , the J. Peterman necklace , and the Asprey necklace . The three necklaces are all very similar but have distinguishable differences . </P>
