It is a Russian Imperial porcelain coffee set consisting of 6 cups and 7 saucers. While looking rather conservative, this set has real gold gilding.
Considering the fact that set's hallmark was in use during 1880-1889 time period, set is in the greatest condition. Time has mildly touched only 1 saucer, it has a micro chip, and 1 cup has a bigger underneath chip in the bottom of the cup.
The hallmark also tells that this traditional looking Russian porcelain set was produced by Kuznetsov's porcelain factory located in Dulevo.
