The third and final design was not used in the film . After the film 's success , Asprey & Garrard were commissioned to create an authentic Heart of the Ocean necklace using the original design . The result was a platinum-set , heart-shaped Ceylon sapphire surrounded by 103 diamonds . This design featured a much larger inverted pear shaped Ceylon sapphire with a subtle cleft to resemble a heart . The chain for this necklace also featured a mix of round , pear , and marquise cut white diamonds . The bail also featured a heart cut white diamond with another round cut diamond attached to an inverted pear shape diamond which was then attached to the cage of the main stone . The necklace was donated to Sotheby 's auction house in Beverly Hills for an auction benefiting the Diana , Princess of Wales Memorial Fund and Southern California 's Aid For AIDS . It was sold to an unidentified Asprey client for $ 1.4 million , under the agreement that Celine Dion would wear it two nights later at the 1998 Academy Awards ceremony . This necklace has since not been made available for public viewing
