Are you looking to appraise or sell a diamond ?
Do not hesitate to contact us and make an appointment at our Paris or Antwerp offices. Our team of gemmologists is at your disposal.
In the case of an appraisal (for inheritance purposes or for your insurance company for example), we will provide you with a document called Replacement Value. This includes the main characteristics of your diamond as well as its value at the current market price.
Why choose DIAMANT-GEMS ?
A sole intermediary
DIAMANT-GEMS is the only intermediary between the mine and the jewellery.
We buy rough diamonds in Africa and in Canada; once they are cut in Antwerp, we present them on the Antwerp and Hong Kong Diamond Bourses.
By limiting the number of intermediaries, we can guarantee wholesale prices to our clients.
A jewellery service is also at your disposal. We have a large choice of diamond rings, earrings, necklaces and bracelets in stock.
In addition to these, our custom-made creations are very popular. Our designers are at your service.
All of our diamonds are certified by renowned laboratories (GIA, HRD and IGI) and feature a laser-engraved number in order to easily identify them.
Sealing can be performed by the laboratories on request.
