I've lost so many real diamond stud earrings and have felt sick each time that I've decided to replace it with Diamonique. I've purchased CZ's set in 14K Gold and also spent a lot more than what I paid for these ones but each one were obviously CZ's.  I've worn the first set for a few days now, was shopping at Macy's fine jewelry for a ring and the sales reps were very complimentary of my stud earrings. They were very impressed with its clarity and of course, I did not tell them they were not real. I bought 2 sets to make sure I had a back-up set available in the event I lose it again.  Delivery was very quick and arrived way before the date I expected it to arrive. I will check out other items they sell in the event I can find a bracelet since I've lost a few expensive, real ones too.
