Brooches by John & Dawn Field This little owl brooch/pin is made from sterling silver and 24 carat gold. The technique used is an ancient Korean one called Keum boo, where the gold is fused to the silver at a high temperature. The brooch has been oxidised, then some of the surface has been highly polished to create a dramatic contrast between the bright gold and blackened silver. We also make matching owl earrings, which can be seen in one of the photographs above.
