I need help, I know nothing about jewellery, I have't worn a ring for years and looking at all these dreadful websites is giving me a headache.

We are thinking of silver rings (my other half doesn't want gold) and to have the one ring elvish etched into it. I can find a thousand different places online but I can't tell if they are good or not. Oh and we don't want expensive, the wedding is costing enough already. What should I look for and what should I avoid?
