Mens Colbalt XF Ring Size 11.5

A rather unique men's wedding ring. Cobalt XF chrome 8mm concave wedding band with beveled edges. The wedding ring is manufactured of cobalt chrome with a high polish inner surface and satin finished beveled ring edges creating a concave appearance on the top surface of the wedding band. The styling of the wedding band is not something that can be found in the more traditional and much more expensive rings made of silver, gold, and platinum. Selling for my Mother In Law and condition is as is...could be cleaned up pretty nice but I dont know much about jewelry.
