A diamond certificate, also known as a diamond grading report, is an easily understood document prepared by an expert gemologist that describes the key characteristics of a diamond. A certificate from a gemological laboratory verifies the quality of a loose diamond and allows non-experts to make educated diamond buying decisions. At BuyFineDiamonds, we rely on 5 highly regarded, internationally acclaimed gemological laboratories to certify every loose diamond we offer. These laboratories use universally recognized standards for grading diamonds.
Founded in 1931, the Gemological Institute of America, or GIA, is an independent, non-profit organization considered by many to be the world's foremost authority in gemology. Introduced in 1953, their diamond and gemstone grading system is recognized worldwide. Manufacturers from around the world send diamonds and gems to GIA for examination and analysis.
When a diamond is accompanied by a GIA certificate, the consumer is assured that the stone has been analyzed by an unbiased gemologist who upholds the highest standards of integrity, science, and professionalism.
Since 1943, the American Gem Society (AGS) has demonstrated a commitment to upholding the highest ethical standards in the diamond and jewellery industry. Driven by a goal to provide premium education for jewellery professionals and consumers, the society offers courses to all segments of the diamond industry. The AGS established a laboratory in 1996 to provide modern grading services for the diamond market.
Its conservative and unbiased approach to diamond grading has made the AGS one of the world's most respected gemological laboratories. Consequently, an AGS certificate guarantees an accurate analysis and evaluation of a diamond.
The European Gemological Laboratory, or EGL, was founded in Belgium more than 30 years ago. EGL is committed to protecting the integrity of the jewellery trade and promoting public interest through applied science, innovation, education, and exceptional service. The laboratory is credited with introducing new approaches to diamond grading and conducting advanced research with physicists, geologists, and mineralogists. An EGL certificate is a valued document that aids consumers in the diamond buying process and is the result of thorough scrutiny of a diamond.
Established in 1975, the International Gemological Institute, or IGI, is the largest independent gemological laboratory in the world, with locations in all major diamond centers. IGI's mission is to provide jewellery professionals and consumers with extensive education programs and reliable diamond and fine jewellery certification
An IGI certificate is comprised of a detailed analysis of a diamond's characteristics by several expert gemologists.
The Hoge Raad voor Diamant (HRD), translated as "Diamond High Council", was established in Antwerp in 1973 as the European counterpart to the GIA. Representing the global diamond trade to public governments and diamond organizations, HRD monitors and reports the import and export of over half of the world's loose diamonds.
HRD is at the forefront of advanced research and education in the diamond industry. Based on internationally accepted standards, an HRD diamond certificate is highly regarded among jewelers and consumers.
