Before purchasing a diamond, you should expect to review a copy of its certificate as proof that it has undergone an unbiased, professional examination.

What Is A Certificate?
A diamond certificate, also called diamond grading report, is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler’s loupe, a microscope, and other industry tools.

Hydeblanc Diamonds Are Certified
Each of our loose diamonds is always accompanied by a grading report (GIA or HRD, IGI, EGL) that includes a detailed explanation of the diamond’s characteristics, including the number of carats, the diamond’s color, its clarity, cut, and dimensions. A certified diamond’s quality is guaranteed, and this makes it more valuable than an uncertified stone. All of our diamonds are also procured from authorized sources and validated through the Kimberley Process, an international certification process that uses strict requirements to control the production of rough diamonds and prevent illicit stones from entering the legitimate diamond trade.

Loose diamonds from Hydeblanc are natural and graded by the world’s most respected grading entities:

- GIA (Gemological Institute of America)
- HRD (Hoge Raad voor Diamant o Diamond High Council)
- IGI (International Gemological Institute Antwerp)
- EGL (European Gemological Laboratory) - Generally grading scale is slightly less strict than other Institute

Hydeblanc sells only certified diamonds and the grading report protect the buyer. Keep in mind that usually mini certificate costs around £50 and a fully certificate costs around £100 to £200 per stone.
