After graduating from art school towards the end of the 1970s, Simon began designing customised silver buttons and jewellery for fashion designers Bill Gibb, Zandra Rhodes, Elizabeth Emanuel, Bruce Oldfield and Jean Muir. This was the beginning of a long association with the world of fashion. During the 1980s and 90s this work quickly grew into an international business covering a wide range of jewellery product related issues. In his capacity as a consultant Simon was involved in establishing international fashion jewellery ranges for Swarovski and own-brand jewellery ranges for Wedgewood, Liberty, The V&A and the British Museum.
