I haven't been there in a very long time. But I do remember that there were some decent deals to be had 15 years ago. At the time a lot of the shops were carrying very delicate, feminine, pretty pieces. Not sure what the trends are there now.
Sadly, I haven't had much time to explore for jewelry. I can ask around and see if anyone I know has any suggestions, though. I will report back with what I find out!
