I inherited my great grandfather's rose gold wedding band. He came to the United States from Lithuania (which was controlled by Russia) in 1909. He lived in Southwestern Lithuania near Poland. The ring has a 56 russian kokoshnik marking with the left facing head which according to information i see on this website dates to around 1900? The assayer marks next to it are hard to read but seem to be a backwards R and a Pi symbol. How did assaying work? Did they inspect the rings at the place of their making or at the place of their buying? It is also marked with a "PB" which might be the makers initials. In some research online, i see that rose gold was somewhat invented in russia a bit before this, and was very popular there. I was wondering if anyone might be able to assist with some additional insight or information such as what "PB" might be, who the assayer might be, where the ring might have been made, or when? Thanks so much
Also of note, the ring was originally yellow gold plated. Any idea why they would gold plate a rose gold ring?
