I bought this claddagh ring over the fall from a shop in Seattle. I think it is Georgian. There is a hallmark right under one of the hands. I took a pic with my stereomicroscope, but I still can’t make it out. Can anyone help? Any information would be much appreciated! 🙏

I recently bought this piece, and I am trying to learn anything I can. It looks to be a claddagh ring from 1700s, maybe early 1800s. There is one hallmark on the outside of the band, but I can’t make it out. Any help at all would be much appreciated!
