Can you get for example a UN certificate?

Answer 1

While the UN (United Nations) introduced the Kimberley Process Certification Scheme (KPCS), the UN does not issue certificates for individual diamonds. A Kimberley Process Certificate matches with a particular shipment of diamonds being transported from one country to another. The World Trade Organization (WTO) oversees investigations when there are accusations that member countries are not abiding by KPCS standards. Individual diamonds are certified by gemological laboratories, such as these: * 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) Certification does not immediately tell you whether your diamond came through the KPCS process. However, certification should tell you: * The inspection date * Shape * Cut style * Diamond measurements (length, width, and height) * Carat weight * Color grade * Clarity grade * Additional information the diamond graders found It might also include: * Cut grade * Fluorescence * Finish's polish * Finish's symmetry * Comments from the grader * Laser inscription * Notes on enhancement treatments performed on the diamond * A map of inclusions and/or blemishes * Clarity characteristics * Diagram of diamond's actual proportions * Photo or diagram of diamond's "hearts and arrows" pattern If you plan on paying a third-party to certify your diamond, ask to see a sample certification first. Make certain the proposed certification will cover all of the areas you expect to be included. One additional thought: Thanks to the Kimberly Process, diamonds mined starting in 2003 carry certificates indicating the location where the diamond rock was unearthed. Before 2003, diamond purchasers might have no indicated of their diamonds' origins, but now they can even name the particular mine. So, if you are looking for UN certification, perhaps your best bet is to buy a diamond mined since 2003 and request the place of origin certification. I found most of this information on www.diamondpriceguru.com and "Kimberley Process Certification Scheme" on Wikipedia.
