I'm not sure about Pandora lab-grown diamonds, but I did buy a ring from QVC's Fire Light Lab-grown diamonds, and it is stunning! (J429243). I also purchased a pair of 2 carat lab grown diamond stud earrings from ShopHQ and they are also beautiful. On the news yesterday there was a jeweler from Cartier (a very famous jewelry store in NYC). He said they are only selling lab-grown diamonds in his store now. He said they are real diamonds without all the controversy about the way natural diamonds are mined. I am very happy with both my purchases.
