When the samurai was prohibited the silver and goldsmiths of Japan lost a market. So they started looking for other markets for their skills.
Shakudo is gold and copper alloy - dark blue in color - close to black.
This cigaret etui is most likely mad in this teknique. With inlaid in gold - trees and house. And silver the Torii gate, mount fuli, and the birds.
Bought by accident - but now much wiser :-)


The 2 last pictures are from back - just black, but then 2 decorations in gold. A bird and makers mark. Any ideas?
Inside also black.
The word Shakudo should be added to "Illustrated silver glossery"
