any diamond of over a carat has a ID # lasered onto it. kinda sounds like this guy was the scammer, sold a ring for $6,000 that wasn't worth $1,000 ......Karma
I am in Tech for a living, this wasn't even a good social engineering scam.. this is what a lack of common sense gets you.. someone get this guys number, claim you're a prince from africa and if he sends you 10k in gift cards you can sent him 15k back.. jeeze..
