Ahead of the Phillips spring auction the British auction house hosted an exclusive cocktail party at the Mandarin Oriental, which showcased a range of artwork, watches and jewelley. Among the pieces up for grabs were artworks by British artist Tracy Emin, American artist Andy Warhol and Japanese artist Yoshitomo Nara. A number of vintage watches and jewellery are set to go under the hammer too—we even spotted Jaime Ku trying on a vintage emerald and diamond Cartier ring.
