Kenneth MacMillan's interest in costume jewellery began in the mid-1980s when he was in New York, working at American Ballet Theatre. His first purchase was a brooch by Miriam Haskell and he went on to concentrate on American makers including Haskell, Eisenberg, Pennino, Hobe and Kenneth Jay Lane. He became a serious and knowledgeable collector amassing over 1000 pieces and in 1992 was asked to loan items to the Victoria and Albert Museum for their exhibition on Jewels of Fantasy. Following MacMillan's death in 1992, Deborah MacMillan was asked to loan items for the exhibition when it toured to the Fashion Institute in New York under the auspices of Swarovski.
