Each piece of jewelry comes with a certificate of authenticity and a detailed description (metal, period, stones, hallmarks). Our network of experts systematically verifies the provenance and condition of each piece before it is offered for sale. For signed jewelry (Cartier, Van Cleef & Arpels, etc.), we also provide archival documents when available.

We ship the jewelry in secure packaging, via courier or postal service with tracking and insurance appropriate to the value.

Average delivery times and available shipping countries are indicated at the time of order. A tracking number is sent as soon as the order is shipped so you can track its progress in real time.
