does this store sell any sterling silver rings? and if so what are the average prices?

Yes, we carry sterling rings. Prices are by weight so they vary a lot by size. Give us a call at 612.872.1292.

For jewelry, the best thing is to check on their website because they get some pieces shipped in, so there's an even wider selection than if you walk in the store

I don't know but you can call them and ask they're really helpful
