We also buy back antique jewelry and family heirlooms containing diamonds or precious stones. We can thus purchase your solitaire diamonds, your diamond rings, or your engagement ring.

If you have a laboratory certificate from one of the major gemological laboratories in the world (GIA, IGI, HRD) for your diamond, we kindly ask that you provide it if possible.

Expert gemologists for over 35 years, Diamantaires OG belongs to a professional circle in the European diamond market that values both know-how and perfect market knowledge.

We offer a precise and complete appraisal of your diamonds, rubies, emeralds, and sapphires. During this appraisal, we study the characteristics of your diamond, notably the 4Cs as defined by the GIA:

• Carat: weight in carats
• Color: from exceptional white to tinted yellow
• Clarity: inclusions within the diamond visible to the naked eye or under 10x magnification
• Cut: the cut and harmony of proportions

To refine the value estimate of your diamond, we will examine other characteristics such as fluorescence. The proposed selling price will also take into account the current diamond market price.
