This ring looks like it should have been worn at the Round Table with the shield designs on the side of it! 

Stainless steel is hypoallergenic, so it won't rust, tarnish, or cause any sort of discoloration. 

Crusader is available in sizes from 8 to 20. This ring has a gorgeous turquoise Howlite stone making it stand out. Howlite is an opaque white or light grey porous stone, marked with black, grey, or dark brown veining.
