I am thinking about selling my hearts on fire fulfillment pendant and trying to figure out what the resale value on it would be. I have read on pricescope and a few other websites that they inflate their prices a lot. WHat's the best way for me to go about selling it? Or what should I expect to get for it. Original retail price was $7000. The center stone is .60 and the 10 surrounding diamonds are .495total set in 18k white gold.
