Hello, it does look like it. I only managed to find a drawing of it, if you have a photo of it and can post it, that would be great.

Thanks a lot.

Thank you, I think this is the best that I can do...

I would greatly appreciate the help with the following hallmark. I think that the ring was attached to the Russian made order of St Vladimir later in Western Europe, possibly France. The order was made between 1821 and 1836.
Thanks
