In 1949, Mario Buccellati was commissioned to create an icon by Pope Pius XII for Princess Margaret to mark the extraordinary power of the first visit of a British Royal to Vatican City in hundreds of years.

His work drew inspiration from nature and Renaissance architecture, frequently incorporating elements such as baroque pearls and detailed hand-engraving, which gave the metal surfaces a fabric-like texture.

In the same year, the Maison celebrated its hundredth anniversary since its foundation that took place in 1919 with the opening of the first boutique in Milan, Largo Santa Margherita, next to the famous La Scala Theatre.

[7] Gianmaria set up shops in Paris on Place Vendome, London, Moscow, Tokyo, Osaka, Nagoya, Hong Kong, Milan via Monte Napoleone, Costa Smeralda, Capri, Elba, Beverly Hills in Rodeo Drive, Aspen and Sydney; Gianmaria has been given several awards for his work as a goldsmith and entrepreneur.

[10] In 2013, the investment fund Clessidra took over the majority of the company's capital to further expand the business through owned shops showing only the label Buccellati.
