About Us

Auctentic, as a broker, evaluates your jewels on the solid base of the values of similar pieces bought and sold on the international professional market. If the communicated range value is of interest, Auctentic looks for the best possible offer in the market. Furthermore Auctentic acts as a guarantor both for you and the buyer by making sure you get your immediate payment the moment we assess the value of the jewel.

Auctentic is a broker specialising in diamonds over 1ct in weight, and jewellery that mounts the same category of gemstones.

We also deal in emeralds, rubies and sapphires over 3ct each, and related jewellery, and have a specific service for pre-owned luxury watches.

In order to proceed, the first essential step is to provide Auctentic with as much information as possible about the valuable item you wish to have evaluated. This can be done by sending the certificate or by sending clear, accurate photos by following the instructions here. Only once the data has been collected can Auctentic provide an idea of the real value of the precious and, if desired, find the best possible offer. In order to proceed with the transaction, it is imperative that Auctentic's gemologists can check the characteristics of the precious in person by arranging insured shipping or an appointment at the offices.

Auctentic, being an intermediary, has no interest in submitting downward values but, on the contrary, is in a position to push bids as far as possible. Moreover, with a network of more than 2,000 interlocutors, it grants priority access to the market of internationally ranked professionals, the only ones always able to make concrete offers. Auctentic also stands guarantor for the total solvency of buyers by reducing credit times. Auctentic is also in constant contact with the international market to have continuous updates on current values and trends. This makes it possible to provide real and verifiable values.

Auctentic's commitment is to provide you with an offer within 1 to 3 working days from the arrival of your jewel in our premises. Of course the selling process is specific to each case because every situation is different and unique. Relax, our people will guide you every step of the way.

Auctentic is a relatively young entity created specifically to help individuals sell their jewelry. However, it has its roots in two international companies that have been in the most prominent circles such as Diamond Exchanges for several generations. The expertise has therefore been built for several decades.
