Wondering if anyone here has had old diamond jewelry they were looking to offload and has any experience getting offers in the NYC diamond district. I have no idea what to expect as offers. For example if you look up the value of a loose diamond with certain specs on Blue Nile, can you expect to have a diamond dealer offer you a certain percentage of that amount? Say Blue Nile says a diamond with certain specs is worth $5k. Would a dealer offer you $2500? $4k?
