David yurman black diamond tag fake?

[Jackiesmith]

Hi I recently purchased the black diamonds tag by david yurman on ebay. Seller seems to be legit with many feedbacks ans previous history. He also mentioned the pieace is 100% authentic. I received the tag and sent it to my jewler and he said the black diamonda are not real. I want to confirm with you does david yurman use real black diamonds? Or just stones? Please advise before i return this. .

There are several eBay listings for this same pendant where the sellers outright state that the pendant is not authentic David Yurman. In fact, I can't find any indication that David Yurman made a black diamond version of this pendant. In any case, David Yurman always uses genuine gemstones.
