Just got this tungsten carbide ring and it's totally amazing. It has a beautifull shine and the multi-faceted pattern is just perfect. Tungsten-carbide rings are a bit more greyish than silver but the shine is like 10 times more. And the best part is that it's scratch proof. I already tested it with my keys and I didn't manage to make not even a single scratch! Finally the price is quite reasonable for a tungsten carbide ring.
I'm definitely going for tungsten from now on. Would highly recomment this to anyone.
