His and Hers Travel Wedding Ring Set

Diamond cut middle and textured edge. There is a spot in the inside of the men’s band and on the outside. Pretty sure with a good cleaning both would come out. Men’s ring is stamped with a “B”, women’s rings stamped with “brass”. Illusion set stone. Pretty sure it’s diamond or cz, but have no way to confirm. These come from a jewelry store that went out of business.
