I am brand new to this, doing much research and purchasing supplies. I mainly come across jewelry bezels that are made of basic alloys and/or are plated with silver, gold, etc. Like any other jewelry won’t these fade/tarnish? It seems there aren’t many real silver, gold or even stainless steel bezels, but I would think there wouldn’t be much point in selling a beautiful, timeless resin piece if the metal is going to fade/rust/tarnish. Are most sellers just selling pieces that will only last a short time and not worrying about long-term quality? Thoughts?
