Boucheron's 'Serpent Bohème' collection debuted in 1968, and the label has since found countless ways to keep its pieces feeling so distinct and modern. Cast from 18-karat white gold, this earring is tipped with a diamond-encrusted pendant at the top, and one inlaid with luminous aquaprase at the bottom - both are shaped to depict the head of a snake. The screw fastening allows you to wear them at a variety of lengths, too.
