The ring is gorgeous. Time will tell if the black coating is durable but we all know that tungsten carbide is quite durable. I ordered it to my size and the ring seems to be very true to size. I had to get this ring because I lost my wedding band in the ocean. This ring is better and cheaper than my last one. The wife likes it too.

EDIT
10 months later, and the black coating has held up to almost a year of working on a 67 beetle, Marine Corps PT, wearing motorcycle gloves, digging, working out at the gym, and all sorts of stuff VERY well. It has one tiny little chip smaller than a pin head from about 6 months ago. It's held up tough. Needless to say, the tungsten carbide itself is still flawless.
