Hi,
Welcome to the forum.
1.Those are not Russian marks
2.Chain and cross are not by the same maker, the cross being older.
3.The stones are garnets (most likely of Bohemian origin).
4.The cross could be gilded silver
5.Marks are too small to be positively identified.The search should be limited to Austria and Czechoslovakia with better close up of the marks.
Regards
