I bought this ring (4 mm sz 6 stainless steel with gold plating) at the same time as another ring that was a "tungsten" version. They arrived the same day, and though the tungsten one cost quite a bit more, the two rings were almost totally indistinguishable from one another in color, size, shape, and weight. The only way to tell which was which was to look at the stamp inside.
  I would have given 5 stars except for two small concerns. 1) There was a tiny dark spot on my ring due to a small speck of imperfection in the plating (but, I doubt anyone else would ever notice it, unless they were a jeweler, like me) and 2) that even though the ring was advertised as 4mm, it measured 5mm which made it look a little more bulky then I wanted, but I'll still keep it just the same. In the future, I'll just take that into consideration when choosing band width here.
  The fit was smooth and comfortable almost like silk gliding over my skin (no edges)and is as good as any "comfort fit" ring could be. Shipping was fast (even this close to the holiday) and the box for this ring was an adorable pink "present". I'd have to say that I'm very happy with my purchase. This ring was a terrific deal.
