Brooches by John & Dawn Field This dog brooch is made from sterling silver and 24 carat gold. The technique used is an ancient Korean one called Keum Boo where gold is fused to silver at a high temperature. The brooch has been oxidised to create a dramatic contrast with the gold and the highly polished silver. We also make a matching pair of dog earrings, which can be seen in one of the photographs above.
