Sterling silver and keum bo ring.
Keum bo is the Korean art of depletion gilding, whereby nearly pure gold is fused to silver. The texture on the ring is created by reticulation, a lengthy process whereby a layer of pure silver is created on the outside of the piece of sterling silver.
Pure silver has a lower melting point than sterling silver and therefore it is possible to melt just the surface of the silver with a torch, without melting the entire piece. The texture is created by the molten silver spinning around, at the moment the heat is removed, the silver remains frozen in time.
This sterling silver and keum bo ring is a one of a kind piece.
