If you'll check the old threads, you'll see that this is an ongoing problem. I can't understand why eBay hasn't fixed this by now. Everyone loses with the system the way it is. A system designed to protect the consumer has in your case harmed the consumer by preventing him or her from buying an authentic item, presumably at a great price.
GIA are experts at gemstone identification and diamond grading. But auction houses and the like don't go to them for authenticating whether or not a designer item is counterfeit. If they can look at an item and clearly determine that the quality indicates an item is not authentic, then fine reject the sale. But they shouldn't reject it simply because an item looks authentic...but they can't verify it. When you have supporting paperwork like receipts, the system is even more dysfunctional.
If the sale went through, the buyer, the seller, and eBay are all happy. When a legitimate sale is blocked, no one is happy. They need to fix this problem!
