Maurizio Fioravanti is a jeweller whose contemporary micro mosaic jewels are so time-consuming to create that he produces a maximum of 10 each year. Sold under the name Vamgard, a company he co-founded with Virginie Torroni, a Geneva-based gem dealer, Fioravanti combines old-world techniques with cutting-edge materials, including titanium and carbon fibre, creating masterpieces of such intricacy that it is difficult to tell they are micro mosaics at all.
