I have a pair of .62ctw diamond white gold earrings appraised at $2050 and were $1000+tax at costco. I have it on ebay right now never worn for $600 starting bid for 5 days with 45 mins left! but no bids and i do not think anyone will bid. so if i took them to a pawn shop how does that work? roughly how much do that pay as in what percentage of the original item cost do they provide, is there anythign you would have to fill out, ID, etc?
