When purchasing a loose diamond you should expect to see a copy of its certificate, provided by an independent third party laboratory. A diamond certificate, also called a diamond grading report, a diamond dossier, or a diamond quality document, proves that your diamond has gone through a thorough and unbiased professional examination. A diamond grading report will evaluate a diamond on many different components including:
The Gemological Institute of America (GIA) and the American Gem Society Laboratories (AGSL) are among the most respected diamond grading institutions used today. Most of the diamonds carried by Allurez are certified by GIA or AGSL. Allurez also offers diamonds certified by the reputable International Gemological Institute (IGI) and the European Gemological Laboratory (EGL). Certification is included with every loose diamond and diamond jewelry purchased from the ‘design your own’ section of Allurez.com
