Hi

I've made a set of earrings which I wanted to be in gold but are quite big and heavy even in silver (10g). Due to their size I'm going to keep them silver and have them gold plated. The issue is that they require a post and a clip, which I've tried and it works well but the current clip looks far too lightweight and flimsy for the earring itself and the price point that I'm aiming for so...
Firstly, do I add a gold clip before the earring is plated or a silver one?
Secondly, where do I buy substantial, strong, high end findings for my jewellery. I'll need a clip that goes over a post.

I'd be very grateful for advice
