Certified Diamonds

Certified diamonds come with a Diamond certification: written proof of a diamond's attributes. Although many diamonds look the same - they are not. Professional laboratories will judge bigger diamonds on the 4 facets Cut, Carat, Color, Clarity).

Certifications are issued by independent gemological laboratories. There are several grading laboratories, the most prominent being:

  • International Gemological Institute (IGI)
  • European Gemological Laboratories (EGL)
  • GemEx Systems
  • Gemological Institute of America (GIA)
  • American Gem Society (AGS)

They will not give a price-estimation but only an independent point of view on the quality of the stone. A certificate with a number that will be lasered into the bottom of the diamond (this won’t influence the price nor one of the 4 C’s).

From the certificate, they will make a micro copy and they will seal it together with the diamond. Those kind of diamonds will offer disappear for many years as part of an investment. Later, on the hand of the certificate, they can track the diamond back and sell it and/or shape it again.

Without it, you have no assurance that the diamond you are buying is of the quality you're paying for.

Certification gives you the information you need to assess a diamond's fair market value. It also allows you to make an intelligent comparison with other diamonds either in the same jewelry store or in another.
