Thanks to all for the great feedback.

-@ Dennis and Peter: Thanks for the tips guys. I think i will try both solutions to see what works best for me, never used a graver before tho. And thanks again for the great advise Dennis.

-@Jayne : For the texture i finished the ring with abrasive papers as i would normally do to prep for a high shine. But instead of the shine i used my file cleaning brush in a crossing motion, left to right and then right to left, while i turned the ring once in a while. And i think the file brush is made from steel.
