||This fairly simple technique has
been an important element in traditional and contemporary Korean
jewelry. It consists of fusing a thin 24 Karat sheet to the
surface of another metal, usually silver. This allows for the
look and emotion of gold but is less expensive and has added
strength. In addition, the process lends itself to various effects,
allowing interesting expression through surface decoration.
Popular with many contemporary Korean metalworkers and jewelers,
keum boo is still highly utilized and it is easy to find metalwork
in Korea that employs this process.
The ring shown is of copper and silver, with various textures
and patinas. There are two layers with keum boo on silver.
