Well there are golden Honour rings that are marked, and talking about Sepp Dietrich, he received a golden honour ring of the city of Frankfurt (Reichshandwerkertag) in 1936 which he wore till his death in 1966.
These rings bear a goldmark and a maker initials mark ( JF = Julius Fuchs) on the inside.
