They're ok .... having purchased tons of C.Z. earrings, these did not wow me the least bit.  For one, the stems were bent almost completely in half.  They were packaged in a plastic bag only ... which is not very good if your shipping something this delicate.  The size is large & with that, you kind of lose the sparkle.  Probably better to buy a smaller size.  Just wasn't happy with this purchase at all.  Don't know how long these will last with very flimsy stems???  Would not purchase AGAIN!
