A delightful and comfortable ring. I am not certain of the stone and it may be glass. Nice weight with all smooth edges, no sharp edges or burrs. In good, pre-worn condition with stones and surface details in tact. Wear is evident and does not detract from the overall aesthetic. There may be a partial crack in one of the side stones, though the stone is not loose or split. No visible stamps in the interior. Thanks for stopping in!
