Is the diamond district in NYC open on Saturday?
Many are closed to observe the Jewish Sabbath, but there are a few that are open. If any are open, they’d be open on Saturday, but not Sunday. Your best bet would be to go during the week. If you’re shopping for a diamond, I would say that the weekend would be the least recommended day. Go there on a Monday, and you’ll see them all open. If you’re in NYC to buy a diamond ring, I would do your research before going to the stores.
