Chat with Diamant Gems


Buying a diamond
or a coloured stone


We are at your disposal to organize a presentation of diamonds, rubies, sapphires and emeralds in our offices. We will receive you in a secure and confidential environment.

A first contact will be necessary to better identify and discuss your requirements. Our team of gemologists are available to advise and accompany you, and show you a selection of certified stones that best reflects your needs.

You also have the opportunity to examine the stones in the best conditions (best lighting, magnifying glasses, colour comparisons).

All of our diamonds, rubies, sapphires and emeralds are certified by leading laboratories (GIA, GIA, IGI). Moreover, in the case of diamonds, the numbers of those certificates are laser-engraved on their girdle (the edge of the stone).

Our jewelry department is also at your disposal to create your custom-made jewelry. After defining your project, models will be offered so that you can participate in the creation of your jewelry.

Contact us for an appointment at one of our offices. We receive from Monday to Friday from 9.00 am to 6.30 pm.


You can also order your diamond at distance by choosing among the thousands of diamonds whose certificates are visible online. In this particular case, contact us for availability of the stone you have chosen. A deposit of 30% will be required at purchase and the balance is paid on delivery.
