Now that chunky necklaces and maximal looks are in again, I thought I'd post a recommendation as to where I got mine: J. Crew factory. I don't find J. Crew Factory to be that high quality when it comes to clothes, but I've bought several pieces of chunky jewelry from there that are in the same league of quality as J. Crew jewelry, but for a fraction of the price, $20-30 vs. $100 at J. Crew.
