Sophie Bille Brahe // Croissant de LuneThe Sophie Bille Brahe Croissant De Lune Earring. This gold diamond single earring was Sophies first ever design and has become her signature, and holds a special place for her: I designed it years ago and still wear it every day, in the shower, on the beach, the gym, everywhere. It has become part of me almost, she says. The Croissant de Lune is a single earring, with a crescent of tapering diamonds that hug the curve of the ear. Crafted in 18K
