Looking at this ring, and looking at the price, I was worried it would look cheap when I got it.  It actually shines and sparkles quite a bit without being too noticeable.  The carbon is very detailed and looks great.  The cuts catch the light nicely.  It's a thick ring, so be prepared.  I really like the 10mm though.  It's heavy, and feels good on your finger.  Super comfortable.  Have had it on for about 48 hours now, and I love it.  Shipping was super fast from The World Jewelry Center.  Ordered on a Sunday and arrived on Wednesday.  Very happy with this purchase.
