Diamond Certificate

What is a Diamond Certificate?

A diamond certificate is a detailed document the specifies the unique diamond specifications like its colour grade, carat weight, cut grade and clarity grade. Therefore, purchasing a diamond without a diamond certificate will not be a wise decision to make. Three of the most trusted diamond grading laboratories will be the Gemological Institute of America (GIA), The American Gem Society ( AGS), and Hoge Raad Voor Diamant (HRD) Antwerp.

The cost of a diamond depends on these unique specifications, otherwise known as the 4C’s - Colour, Clarity, Cut and Carat. Even though carat determines the price of a diamond to a large extend, the colour, cut and clarity determines the look and feel of a diamond.

GIA Diamond Certification

GIA or the Gemological Institute of America is a non-profit, independent organization. It was founded in 1931 and is considered by many to be the world's highest authority in gemology. Their diamond and gemstone grading system was introduced in 1953 and is recognized worldwide. Manufacturers from around the world send gems and diamonds to GIA for evaluation and analysis.

A diamond or gem that comes with a GIA certificate has been analysed by an unbiased gemologist. The GIA certificate assures the buyer that the stone is certified by an institute that upholds the highest standards of science, integrity and professionalism.


AGS Diamond Certification

AGS stands for American Gem Society. Since its inception in 1943, the organization has demonstrated a commitment to uphold the foremost ethical standards in the diamond and gemstones industry. The organization established a laboratory in 1996 to provide modern grading services for the diamond industry. Additionally, the society strives to provide premium education for jewellery professionals and consumers alike. With this goal in mind, they offer courses to different segments of the gemstone industry.

The AGS follows an unbiased and conservative approach towards diamond grading. This has made them one of the most respected gemological labs in the world. That is why an AGS certificate assures the buyer an accurate evaluation and analysis of a diamond.


HRD Diamond Certification

The Hoge Raadvoor Diamant (HRD), translated as the "Diamond High Council" is the European counterpart to the GIA. It was established in 1973 in Antwerp. Currently, the HRD represents global diamond trade to diamond organizations and public governments. Consequently, it monitors and reports the export and import of over half of the world's loose diamonds.

HRD also leads the industry in advanced research and education in diamonds and other gemstones. That is why an HRD diamond certificate is highly regarded among consumers and jewellers.
