This Stingray ring by Rachel Roy is my favorite of this season's RR rings, although they are all adorable and....cheap! I just purchased this ring for about 40 bucks, if you hurry there is an additional 30% sale going on right now. I didn't even know that Rachel Roy had jewelry until I saw it on The City (a surprisingly good show - don't make fun!). Anyway, I highly recommend checking on RR's website, everything if fun, elegant and affordable.
This is the Coral ring
And the Beetle ring.
