7mm jump rings, but I don't use them for the dangling ... I hook directly thru the hole at the bottom. And I think you want 10mm for beading (dangling anyway). It might be 8mm for stringing. I would suggest that you use sterling silver findings (jump rings, etc.) Eventually the fake stuff wears and it looks crummy (not so great for repeat customers). JMO.
