BOUCHERON Serpent Bohème 18-karat gold, lapis lazuli and diamond single earring

Boucheron's 'Serpent Bohème' collection debuted in '68, and the label has since found countless ways to keep its pieces feeling distinctive and modern. Cast from 18-karat gold, this solo earring is tipped with a diamond-encrusted pendant at the top and a faceted lapiz lazuli at the bottom - both are shaped to depict a snake's head. The screw fastening lets you wear them at a variety of lengths, too.
