Certification
of diamonds

Any grown IQ Diamonds diamond can be accompanied by a Certificate of an independent gemological laboratory at the request of the buyer. This document specifies the exact parameters of the stone, the shape and type of cut, the characteristics of color and purity, the quality of polishing, cutting, symmetry. The certificate has a unique number and is immediately entered into the electronic database of the gemological laboratory that issued it.

Such a passport significantly increases the value of the stone, turning the diamond into an excellent investment.

IQ Diamonds are certified by non-profit organizations:

Such a certificate is issued only for unadjusted diamonds. If the diamond is already fixed in the decoration, it is possible to obtain an Expert Opinion in independent gemological laboratories. In such a Conclusion, there must be a photo of the jewelry, a full description of the material from which the jewelry is made, a sample of the precious metal and a full description of the diamond (diamonds) fixed in the jewelry. Some IQ Diamonds products already have Certificates and Expert Opinions, which you can see in the product description card in the catalog on our website. Those diamonds or finished jewelry that do not have Certificates or Expert Opinions are sent by us for Certification at the request of the buyer for an additional fee according to the rates of independent gemological laboratories.
