Where to find designer wedding rings?

[Lowson]

Our wedding is coming up in exactly a month and we still need to sort out the rings. I'm perfectly fine with a basic classic gold band for myself. My fiancée is looking for something much more exquisite with a custom designer touch to it. We've checked a few regular stores at the mall but everything looks exactly the same. What are some good places to hunt for unique bridal jewelry right now?
