Well. there is al lot to tell about this ring holder. First of all....... sorry..... it is not antique not vintage nor old. It dates from the 1980s. Is made by RCR in Italy at Colle di Val d'Elsa. It is a single piece, not a part of a trinket set. And..... it is not rare. I could also say..... you see it everywhere, in all countries from the US , Canada, UK, France, Italy, Denmark. At least that's my experience. If one is looking for a ring holder, big chance that this will be the first one you will find.
