Earrings by John Field These ear studs are made from sterling silver and 24ct gold. The technique used is an ancient Korean one, where the gold is fused to the silver. Letters and symbols have been punched into the surface by hand, so each pair will be slightly different. The surface of the earrings are given a worn effect to simulate the look of an antique found object. These ear studs measure 13mm in diameter and have been domed so that the front surface is concave.
