I think this Australian method of hallmarking is good. It seems
that we in the states need to update our stamping laws to include
something like this. Simply not stamping an item because I can
find no room to stamp each area separately is not satisfactory.
The Australian standard has some fairly large loop holes so that a
person that uses mixed metals can can stamp according to the
We used to have a gold stamp for settings and a gold stamp for gold.
Now we’ve got one stamp for gold, one for silver, one for platinum
and one for palladium, the rest are chemical symbols. However
stainless steel can be SS or StS (imagine stamping the formula for
stainless steel :-D)
I was concerned that I couldn’t stamp any mokume gane created,
fortunately this is not the case.
