Marina Bulgari was born in 1930 into one of the world’s most famous family jewel houses, and grew up in Rome, Athens and Corfu. She worked in the family business for several years before launching her own jewellery range in 1976, making her name as one of the leading women designers of this generation, whilst honouring the Bulgari family’s long and prestigious heritage. Her bold and contemporary designs, with a strong Italian flavour, proved hugely successful, and Marina opened her first showroom in Geneva in 1978, with further boutiques following in Milan, Paris and New York, Jeddah and Tokyo. She designed a signature cut and shape of gemstone - between a pear-cut and a triangular-cut - which can be found throughout her jewellery designs. In 1999 Marina sold her company to the Sheik of Jeddah, Ahmed Fitaihi, of Saudi Arabia.
