I am looking for neclaces or braclets
I would go to Portugal. I think you can find the best stuff there. From what I understand, most of the things you can buy online or in other countries are actually made in China. So, if you are interested in supporting Portuguese artists then go take a holiady to Portugal and find some really authentic jewelry. It would be much better in the long run, more valuable, and last a lot longer. Are you looking for traditional or modern?
