A diamond is most likely the most expensive jewelry investment a person will make in a lifetime. With that in mind, it is important to verify the authenticity of a piece of diamond jewelry. GIA, the Gemological Institute of America, is a reputable international organization that can certify diamonds as well as other precious gemstones and jewelry.
The GIA has set the standards for diamond jewelry by defining several important specifications such as the “Four Cs”. The Carat, Color, Clarity, and Cut are the most important features that define the value of a diamond. The GIA operates several laboratories that can provide comprehensive and accurate reports about the “”Four Cs”” and other important characteristics. For example, the reports can verify whether the diamond is synthetic or Cubic zirconia. The GIA can also investigate if the diamond has been refinished and treated multiple times and whether it includes invisible impurities inside. Additionally, the reports can check for microscopic laser inscriptions of authentic ID numbers. Also, the GIA can inscribe with lasers custom messages or identifications.
The GIA can provide reports on diamonds to anyone in the world. The organization operates labs and educational facilities in cities with major diamond industries in Europe, Asia, and Africa. In the United States, the GIA has two locations, in New York City and Carlsbad, California. Diamonds, or any other gemstones, can be submitted either through shipping or in person.
To submit diamonds to the GIA laboratories, some paperwork needs to be filled out. The Client Agreement form needs to be signed, which will also cover important documents such as the Patriot Compliance Act and Kimberly Process Certification. Shipments should be done through the United States Postal Service, particularly registered mail. The report fees will be based on the size, type, and quantity of diamonds. Several payment methods are accepted such as checks, money orders, and wire transfers. It is important to keep in mind that the GIA will only check for technical specifications and not provide appraisals on diamonds, which should be done by a local jewelry dealer.
