Created by Garrard & Co and made out of 187 diamonds and five South Sea pearls, the necklace was worn by Diana during an appearance at a performance of Swan Lake by the English National Ballet at the Royal Albert Hall two months before her death in 1997. The necklace was created together with a set of earrings, but following her death the suite was sold with permission from her family. The necklace was sold to a Ukrainian couple in 2010 who put it on sale in 2017 at Guernsey's.
