oooh, I have those! I love them. They were a gift from my stepmom, though -- I think she bought them at a boutique on one of her trips. I think mine are real, but I don't really want to grill her about it, so I don't bother.
FYI, I wouldn't worry too much about whether they're real or not. The Chanel ones aren't even real gold or diamonds -- they're just rhinestones and silver, like the knockoffs. So if you get a decent knockoff pair, it's really the same thing.
