This round Japanese Export silver box has the most beautifully crafted inlaid metal ( mokume -gane ) lid made from the tsuba or hand guard of a samurai sword.
See the photo of the interior of the lid.
Mokume-gane is a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns
The border of the lid has been worked with dragons, there is a phoenix at the top and a scene has been worked in the centre of the tsuba.
A very fine piece with a special history.
