VISITORS to this week's fair will be able to enjoy jewellery pieces from an Estate and Antique collection considered to be one of the world's most prestigious. Fred Leighton's collection has jewellery from every era, including the graceful Art Nouveau, Art Deco, the 19th century, the 1940s - considered a time for audacious designs - and from as far afield as Europe and East Asia. For the fair, he is presenting Art Deco jewellery designed by Van Cleef & Arpels, Cartier, Mauboussin, Boucheron and Bel Perron. He has also chosen court jewels of 19th-century Europe and exotic treasures from Indian maharajahs. New York-born and bred, Mr Leighton was driven to collect by a love of beautiful things. As a young man, he opened a Mexican import shop in Greenwich Village, Manhattan, and stocked a wide variety of goods: hand-painted sculptures; colourful paper flowers; hand-embroidered garden frocks and wedding dresses; and Mexican and American Indian jewellery. He developed a more refined taste for jewellery, and in particular, a love for delicate, Victorian, one-of-a-kind pieces. However, in searching for them, he was astounded to find that jewellers would destroy old pieces, melting them down and using the diamonds and precious stones to mount into modern pieces. This is what started him on his quest to obtain every piece of beautiful old jewellery he could. Now, his collection is considered one of the world's most prestigious. of Estate and Antique pieces, featuring every design period. Twenty years ago, he and his wife Glorya moved the Greenwich Village shop to Madison Avenue. Mr Leighton's search for special jewellery continues - now with the help of his daughter.
