> Consumer grade diamond is a propped up market where the cost and price disfunction is about as big as it can be. A few years ago I purchased a pair of diamond earrings for myself at one of the big chains. Kay I think it was. When I paid I was prompted to get a paper receipt or have a receipt emailed to me. I hit paper and then decided I probably should have gone with email in case I needed to get them serviced or anything so I asked the woman helping me if I could change my selection. The two women working spent quite a bit of time at the computer trying to figure it out before one of them said "I'm just going to do this and be done with it." I should have known that wasn't a good sign. They must have added my email address as some sort of corporate/store account because I was emailed a copy of every receipt for every. single. purchase. made at that location from then on. I called the location, I called their headquarters, I talked to someone in IT at HQ. The receipts kept coming and no one at Kay knew why nor did they seem to care. I finally just gave up and abandoned the gmail address but I've often wondered if I'm sitting on one of the most comprehensive consumer diamond data sets of "retail price" vs "purchase price" in the world.
