Don't expect to get even half what you paid for it. Used jewellry is a dime a dozen. If I were you I would try sell it on
www.kijiji.com its a free site and ive used it alot..just make sure you go to the canada page first, then calgary (if this is where you live) Don't go to a pawn shop! I tried to get rid of my old jewellry from my first marriage, they were willing to give me 40 bucks for a 700 dollar diamond wedding band..and 25 for a gorgeous opal and diamond ring that was only worn twice and was very new
