Looks great, feels good, affordable price and I would recommend it to anyone looking for those qualities in a ring.
The single image you get of this ring make the black diamond look bigger than it actuality is and the light makes it seem there was an extrusion when the gem is held, this is not the case, the ring is completely round.
What's more even though the Tungsten Carbide is scratch resistant the transparent material they use to house the Black Carbon Fiber is not. I took it to they gym and, thinking it was 100% scratch proof, I ended up giving ti a "smudged" look to the underside after one round of dumbbells. I now make sure to take it off before working out.
I have no real regrets on my purchase and would buy from them again if I need another ring.
