My original ring was very plain gold band, that never held a shine for very long, and was prone to wear and nicks. I really liked the look of this tungsten ring, so I had my wife buy if for me. Of course this is after I already bought her an updated ring : ). I used a ring sizer at a jewelry store, using my old ring as a guide. Ordered a 10.5, but I probably should have gotten a 10. It doesn't slide off, but is pretty sloppy on my finger. I may just buy a size 10, and keep this one put away for my larger years. As for tough, I accidently scraped it on the bottom of a cement pool, and can see no where on the ring where it was touched. It maintains it's sparkle, and the carbon fiber is very nice to look at in the light.
