Keum Boo silver and gold ring

0 star rating

Keum Boo

Slowly but surely gold is making its way into the Rōff Jewellery collection.

I like the way the 24kt gold flakes contrast with the black silver.

This stunning effect was accomplished by the ancient Korean gilding technique of Keum Boo (also known as Kum-Bu).

Keum Boo is a method of applying pieces of 24 kt gold leaf on heated silver.

With the right temperature and pressure, the gold leaf and silver atoms are exchanged to create a permanent bond.


Oxidised silver

After this stunning silver and gold bowl ring was carefully polished, I applied a special liver of sulphur mixture that oxidises the silver and gives it an amazing bluish black patina.


This remarkable Keum Boo ring has a thin hammered band and is adjustable in size.
