I have purchased 3 David Yurman items on the RealReal. Two have been authentic. The one I received about two weeks ago was a fake. I sent it back and received a refund with no problem. It seems their customer service is better now than it was when some of these comments were posted a while ago. It is troublesome, though, that the company claims that all jewelry items go through official inspection by a certified gemologist. The color of the piece was off, the weight was light, and the stamp had flaws. Compared to the same necklace in a different color that is authentic, this piece was so obviously a fake that I can't believe it would pass any inspection. Purchase from the RealReal only if you know the brand you are purchasing fairly well to decide if what you receive is authentic. I would never take a chance with "final sale" items on the site, though.
