This bespoke bracelet is about as cool as you can get without wearing a lava lamp. London’s Royal College of Art graduate, Beau Han Xu, brings sculptural forms to the body. I first met Chinese designer Beau over coffee two years ago when he showed me the prototypes for his Splash! jewels, which are now in production. His hollow glass sculptures capture the ever-shifting forms of water in all their free-flowing glory, complete with stray droplets. But that is not all. Inside, hundreds of crystal diamonds float in a unique “carrier liquid”, creating a shimmering, ever-changing spectacle.
