How does it work?

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.

How long will it take to receive my payment?

The Wise circuit makes it possible to have transfers credited to almost any bank circuit within a few minutes. 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.

plusminus
How will I receive payment for my piece/s?

Auctentic uses non-revocable instant transfers via Wise circuit.

plusminus
Do I have to pay if I don’t end up selling?

plusminus
What should I include in my shipping box?

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.

plusminus
Why do I have to ship my piece/s to Auctentic?

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.
