Where can you sell your precious stones?

Where can you sell your precious stones?

The value of diamonds and jewels always changes, so it is important to 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.
Many prefer to try to sell in the area with a trusted jeweler. However, in most cases, even the trusted jeweler cannot offer a reasonable amount, while online, finding solutions to receive more generous offers is possible.

With Auctentic, we have developed a way of selling jewelry that guarantees you reliability and satisfaction. By selling only to qualified buyers, we can always guarantee you the best valuation for your jewel. You can quickly complete the entire procedure from your home and receive payment by immediate bank transfer within 24 hours. Do not forget that your jewelry is safe and insured all the time.

How to get a good price for your precious stones

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.
