IGL and GIA certificate, what is it?
Why and who needs a certificate of authenticity
You, as a client, want to receive jewelry made of precious metals with real diamonds for your money. How do you know that you are not being deceived?
A certificate of conformity is a product passport, which is issued after an independent gemological examination for each individual item of the product. It guarantees the authenticity of the jewelry and proves that its performance meets the current quality standards. For these purposes, the document is assigned an individual number, a QR code and a holographic seal.

The certificate of conformity contains detailed information about the object (sample, material, purity, weight, impurities). More details about the gemstone:
- Name of the examination
- The name of the center that carried out such an analysis, its registration number, address, telephone number, postal address on the Internet
- Date of laboratory check

According to the international rules for the classification of diamonds: they evaluate and issue a certificate only for diamonds of natural origin and for natural cut emeralds. Artificially grown stones are not subject to conformity assessment, information about their origin must be printed on the label.
