I got two of these to wear on either side of another ring, which is sterling silver. I actually ordered two of these stainless steel rings as well as two sterling silver rings (also 2MM), and I could not tell the difference between the four rings. I kept the stainless steel ones because they were cheaper, and now after about a month of daily wear, I can tell that the stainless steel rings have not scratched at all in comparison to the sterling silver ring in between them. It definitely makes me want to buy more stainless steel jewelry, especially for daily wear!
