Whether you are thinking of selling the jewels you no longer wear to monetize or the ones you don’t like anymore to buy new ones, the most important thing is to be sure to sell your jewels at the highest market value and in the safest way.


The value of diamonds and jewels always changes, so it is important to really choose the best place to sell them to meet your needs and receive an appropriate offer.
Selling jewels at the gold shop or at the local jewelry store is not the best idea because the markup of the retail sale means receiving offers far below the market value.
In fact, many prefer to try to sell in the area with a trusted jeweler. However, in most cases, even the trusted jeweler does not have the possibility to offer a reasonable amount while online it is possible to find solutions to receive more generous offers.

By selling only to qualified buyers, , we can always guarantee you the best valuation for your jewel.

You have an immediate advantage by selling your jewelry online: you get higher offers. If you only have one buyer, he decides the price. If you have more buyers, you will more easily reach the real market value of your jewelry.

Auctentic helps you to get the price as close as possible to your expectations, even without going to auction, because your valuables are immediately submitted to a select group of genuinely interested buyers, who bid with immediate payment.

A good way to make sure you get the best price is to know the value of what you own.

The characteristics of a jewel cannot be determined with the naked eye, therefore the certificate issued by a gemological institute of proven seriousness and the evaluation of an expert are essential when you want to sell your jewels. The certification does not certify the value of the diamond, but it impartially certifies all its qualities, also stating whether the stone is natural, synthetic or has been treated to enhance or modify its appearance.

The benefits of these certifications are reflected directly on your object because they represent international recognition, due to the respect, trust and impartiality enjoyed by the diamond industry and by buyers.

What factors affect the value of jewels?

There are five big factors that those who buy diamonds and jewels keep in mind when analyzing a piece of their interest:

The 4 C’s of the diamond

Carat, Color, Clarity, Cut


Famous brands maintain their exclusivity over time, standing out for excellence and style


As with high fashion, color, rare cuts or a sophisticated design are also worth more in jewelry


If a piece of jewelry has scratches or marks, it is always good to have it cleaned and polished before selling it

Historical period

For some pieces of jewelry, age adds value such as vintage jewelry from 20-30 years ago and antique jewelry more than 100 years old.
