Sold a Blue Diamond Ring that was a gift to me, the lady went to the Charm store in Medicine Hat, was told by one of the sales ladies that she could tell by just looking at it, before putting it on one of the machines they have there, that she knew it wasn't a real diamond, and after doing whatever she did, told my customer that yes, it's not real, in fact, she didn't know if it was even any kind of a gem stone. This was sent to me right after leaving the store. I gave my customer her money back, she has every right to believe whomever she wants, however, I took it to someone who also knows how to use a Jewellery Loop, and a Diamond Tester, and in fact, the Blue Diamond is a real Diamond, with the same qualities a real diamond has. The earrings to the set, they were real too, and were tested by a local, reputable jewellery company, not impressed, no one can tell if a stone is real or not by just looking at it, so I'm not sure what their intention was, but they made me look like a liar, and someone who would take advantage of an older person. I insisted the lady who bought the earrings get them tested, even though, the sale had already taken place and she wasn't questioning whether they were real. read more
