I had forgotten all about this ring. My father bought it for me a long time ago as he knew I liked silver. He hadn't realised that it is actually a poison ring as the side is hinged to reveal a secret place to place any poison! Just open the ring and tip it into a drink, just like you 've seen it in old films! Apparently it is Mexican. I've never come across one before or since and wonder if it was ever used!!!!!
