Hi Aguest -
on the cgarette case above no Samorodok ( watch your spelling!) technique was used. It was "pebbled" with different small punches.
SAMORODOK
Samorodok is a Russian word meaning that the metal is in its pure or natural state.
The samorodok (reticulation) technique produces a textured nugget like effect simulating a molten surface.
This result is obtained by heating gold or silver to a temperature near the melting point and cooling it abruptly in water.
Some examples from my collection where you can see the difference.
Handbag

Cigarette cases in Gold and Silver and Silver, artificial black oxydised




Match box cover


These objects were mostly by the better firms ( Bragin, Morozov, Archarov, 5th Artel Moscow etc.) produced.
Regards
Goldstein
