Estimates are based on GIA certificates for diamonds with Very Good (VG) or Excellent (EX) cut and symmetry, and fluorescence ranging from None to Medium. The calculator uses market data and valuation algorithms to provide an approximate value. Always consult our gemologists for precise assessments.

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.

In order to proceed, the first essential step is to provide Auctentic with as much information as possible about the precious 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.

There is a possibility, especially around lunchtime and on Friday afternoons, that individual branches will suspend the entry of transfers by communicating batch times that are normally about two hours. Those delays are only imputable to the receiving bank and can not be modified by the paying bank.
Auctentic uses non-revocable instant transfers via Wise circuit.

No, no fees are charged to sellers.
Auctentic earns solely from commissions and that is also why there is no interest in sending downward bids.

Auctentic relies on Malca-Amit, an internationally recognized value carrier. In 2 working days you are sent to your domicile the material needed for packing. Pickup, also at your home, takes place at a later time and is arranged by prior arrangement. From the time the package is handed over to the courier to when it arrives at our location can take from 1 to 3 working days.
It is important that the valuable be protected from being hit by using a small box, cotton, or shot paper. If you have it, the gemological certificate should also be put in the package.
Together with the packaging material you'll also receive the instruction to prepare the shipment. If you prefer, you can ask to be helped via videocall by our operators.

The analysis of the precious is a fundamental step. Auctentic as an intermediary must vouch for the quality of the precious and be able to check its gemological and manufacturing characteristics. The only way to proceed with due professionalism is by viewing it in person, and shipping is by far the quickest and safest way to proceed.
