Lorenz Bäumer's work explodes with colour and joy. This US-born Frenchman has had a career as dazzling as his jewels. As well his own eponymous jewellery brand, he is the Artistic Director at Louis Vuitton's Fine Jewellery and was previously at Chanel overseeing watches and jewellery. There are few big luxury names he hasn't bestowed his talents on, but this is the raw, unfettered Lorenz at work.
