Antique jewelry in Italy?

[lovetodream]

Our family is headed to Italy in a few weeks, and I wondered if anyone had any must-have places I could find a gem of a bargain (see what I did there?!?) or keepsake. Unfortunately, I'm allergic to gold, so the iconic neighborhoods that sell it won't be a great fit for me. Is it worth looking for something in platinum in the country, or should I just enjoy the wine and stick with leather?
