With over 15 years of experience in fine and high jewellery — including a significant tenure at Van Cleef & Arpels, and with further collaborations for Cartier and De Beers — Cecilia combines deep expertise with a refined, intuitive eye. During her tenure, she specialised in High Jewellery Marketing across key European markets and further refined her global perspective through a professional chapter in Dubai.
Jewellery has always been her passion — a lifelong pursuit rooted in beauty, meaning, and craftsmanship. Her credentials include a GIA Diamond Graduate diploma, ongoing studies in Coloured Gemstones, and an ever-growing knowledge of jewellery history. She draws on a discreet network of trusted dealers, artisans, and makers — valued not only for their mastery but also for their integrity and commitment to excellence.
Shaped by Italian and French roots and life in London, Cecilia brings together business expertise and artistic sensibility. Her strength lies in bridging the world of high jewellery with a more personal, boutique approach, offering clients both privileged access and a discreet, thoughtfully considered experience.
