unspecified: how a diamond certificate can benefit you !
June 26, 2013

Buying a certified stone is important for number of reasons. If the diamond is not certified, there is a good chance you may be buying a stone that is one or more grades below stated values in terms of carat weight, color, clarity, or cut. Without a certificate, that is issued by a reputable agency, such as GIA, AGS, or EGL, or HRD, a buyer relies on a jeweler’s integrity that the diamond’s 4C parameters are accurate and not overstated. Without a certificate that certified that the diamond is true to its characteristics a jeweler can take advantage of a buyer, essentially charging him or her for a diamond of higher quality.
Not only can the stone possess characteristics that are less than it is said to be, the diamond may also be treated. Treated stones are much less valuable than natural stones.

When buying a diamond, your safest bet is to buy one that has been certified, that way you know that you are getting what you pay for. Below are a list of a few of the most reputable certification agencies in the United States and Europe,

  • Gemological Institute of America (GIA)
  • American Gemological Society (AGS)
  • European Gemological Laboratory (EGL)
  • Diamond High Council (HRD, which is an abbreviation of the Dutch “Hoge Raad voor Diamant”)
  • International Gemological Institute (IGI)
  • International Confederation of Jewelry, Silverware, Diamonds, Pearls, and Stones (CIBJO)

Be careful. Happy shopping.
