Gemvara

I was thinking of getting my wedding band from Gemvara and I was wondering if any of you had experience (or have friends/family with experiences) with Gemvara? They have a good return policy, so I think it should be okay. But I do wish I could see the ring in person first. It's a beautiful tanzanite band, and I can't really find anything like it elsewhere so I'm pretty sure I'll be getting it at Gemvara.com. Let me know anything you've heard about them, please. TIA!
