Brooches by John Field This brooch is made from sterling silver and 24ct gold and it measures 30mm in diameter. 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 one will be slightly different. The surface of the brooch is given a worn effect to simulate the look of an antique found object.
