Upon arrival, every item is put through our strict authentication process and carefully inspected by our team of in-house authentication experts. We look for brand markings, date codes, serial tags and hologram stickers. Once these items have passed the initial test, a secondary inspection is completed by a third-party authenticator, who is the gold standard in luxury authentication. Our jewelry and watches are authenticated and appraised by a gemologist and come with a valuation certificate. We guarantee all of our products to be 100% authentic.
