I made my first bracelets using silver-plated clasps (not from Fire Mountain Gems and Beads) and they discolored. I want to make good quality jewelry for gifts and don't want to waste money buying precious metal findings if they're not necessary, but I also don't want my pieces to tarnish easily. Can you guide me on when to use precious metal findings? What's the shelf life on silver-plate and gold-plate? I have asked others and researched online but am not getting a clear answer. Again, I might just have started with poor quality clasps and maybe both Fire Mountain's silver-plated or sterling will give me good results in all cases.
