This is a FLOP!! The gem says it's Swarovski, it is pretty.. however, when I tried to open the clasp, it immediately BrOkE!! That was upsetting. My husband bought this for me, it was the 1st purchase either of us made and the only thing to arrive so far. We are going to return it. The description says it has a 2 inch extension, I'm not sure if that comes on the necklace, or it is supposed to be separate. If so, I did not get the extension. @josh_barker68
