One of my roommates purchased these rings recently, and they really are quite lovely, and were only about $22, including shipping.

I find their simplicity charming. Unfortunately, that particular shop is on a break until July. However, if you don't feel like waiting that long, I managed to some other interesting and inexpensive rings in the spirit of those two.
I think they're all pretty darn good-looking, and I would love any of them. The best part is that they're all under $15! Click on the pictures to go straight to the listing on Etsy!
Happy Fashion Fridays everyone, hope you have a lovely weekend!
