Very disappointing product. It is true that it is very attractive but the quality is not at the rendezvous. Zircon can get quite illusion but the media really impressive "gadget". Also I returned to Amazon (which had never happened to me since I am a customer at home) because the clasp and took absolutely no risk of losing the loop was 99% in the day !! By cons nothing wrong, as usual, on Amazon. Fast shipping and reimbursement.
