A diamond certificate is a document thanks to which you can be sure that you are buying a real stone and its price is justified. Certificates are issued by independent gemological centers, after a thorough diagnosis of the stone and analysis of its key characteristics (color, clarity, facets, and weight).

Although there are generally accepted standards for diamond quality, the conclusions of different organizations may differ slightly. So, you need to trust only the authoritative centers.

In Ukraine, the most popular certificates are from the Gemological Institute of America (GIA) and the State Gemological Center of Ukraine (GGCU). By the way, the GIA is one of the most reputable organizations in the world when it comes to diamond valuation.

Other reputable centers that guarantee quality assessment:

  • American Gemological Society (AGS);
  • High Council for Diamonds (HRD);
  • International Gemological Institute (IGI);
  • European Gemological Laboratory (EGL).

It is important that a Certificate in Ukraine can only be obtained for a diamond weighing 0.3 ct or more.
