"Buy used and save the difference".....
Looking at the current physical state and the trend/style of the band, I believe this is a "used" ring. Most likely purchased from a pawn shop rather than a jeweler because a jeweler could do 3 minutes of work to the ring and it would look so much better (and gain them more profit).
Posting pics of the ring comes across as so boastful and not in line with their morals (or the morals they sell to people).
