I really am diggin this ring.
The size conversion is off a bit though, at least with mine.
I got a No.24 which is suppose to be a 12US. I think it's actually an 11.5US.

Here's a size 12US ring I bought from a store in Austin just for comparison.

I'm going to get it stretched half a size if I can. I wear a 12US on my index and middle fingers.
