I have recently bought this ring in Normandy, France.

It is a gold plated silver ring. I have been able to identify one of the two hallmarks as a Belgian mark for small silverwork from the 1800s. I have been unable, however, to identify the other one. Although it looks like a capital "B", the small disconnect between one of the curves and the line makes me think that is not the case. Also, I haven't found any design of a capital "B" hallmark with a similar symbol on the upper part. I also considered a lowercase "a", but have found even less similar designs. I have found it really looks like a georgian მ, Ⴒ or Ⴜ, depending on how you look at it. But information on georgian hallmarks seems to be really scarce on the internet, and I have no access to bibliography on the subject (I live currently in Brazil).
I thank you all for any help you could give me!
