Identifying Antique Rings: Unraveling Markings & History

Question
I have a poison ring with what looks like a mother of pearl stone on it and on the underside of the ring has what appears to be the initials HBP with a design around it, also in another area has the letter L with a stamp/engraving of a cup or possibly mug or bowl around the L. Could you tell me anything about this ring, I cant find anything about maker or anything.  

Answer
Hello Jessica and thank you for your inquiry. I believe your ring is foreign manufacture but finding the mark might take some research. I have listed a site below that might be of some help to you. It contains world hallmarks and since you havea visual of the mark you may be able to match it up with one of the pictures.  Just copy and paste the url below into your browser address field and hit enter:
