If you have a gemological certificate issued by a gemological laboratory, we can give you a first estimate remotely. If we agree on the price, we will collect the stone, along with a form to fill out, which we will have sent to you beforehand.

If the stone is not accompanied by a certificate, we meet for a detailed expertise and we will offer you a trade-in offer, in line with current market trends. If you accept this offer, we will pay you by check or wire transfer, in exchange for your stone and a transfer certificate (which will include your contact details, as required by law).
