It seems like it would be. But research on it points more to it meaning its Italian (vs China, etc). I'm currently reasearching MANY jewelry pieces I have recently acquired. I end days with a headache and blurred vision. Lol!
Not trying to take this off path, but where did you find research on it? I too have many pieces that have something on them and I can not find anywhere to find out what it means.
I just type in characteristics of the piece in a search. A lot of times in different ways. I also check ebay a lot. There are costume jewelry sites, and vintage jewelry sites. I just check everything I can think of about the piece. It's very time consuming and dont always get answers. Hope that helps, Dawn
