I'm trying to find out who does this mark belong to. I can't find it anywhere. Even though it says Italy, it does not have the standard Italian initial-number mark, just the CA mark.The necklace looks like it's a recent production, maybe last 10 years?
I will be very grateful for any help. Thank you in advance.
