CERTIFICATION


Once diamonds are manufactured, a diamond certificate is issued following an unbiased and professional examination to authenticate a diamond's characteristics. The carat weight, colour and clarity are all graded, together with the diamond's exact measurements. Cut grades are also measured for Round Brilliant cuts. Certificates are essential in determining a diamond's value.

There are five main grading laboratories in the diamond industry all of which produce their own grading reports and certificates according to their own standards.  These include the GIA (Gemological Institute of America), AGS (American Gem Society), HRD (Hoge Raad Voor Diamante), IGI (International Gemological Institute) and EGL USA (European Gemological Laboratory United States America).

The GIA is the foremost grading authority in the diamond industry, respected worldwide for the rigorous and objective standards it applies to the evaluation of diamonds. At Eight & Diamond every one of our diamonds have been analysed, graded and certified by the Gemological Institute of America (GIA)., the foremost grading authority in the diamond industry, respected worldwide for the rigorous and objective standards it applies to the evaluation of diamonds. 

All GIA diamonds carry a unique laser-inscribed registry number and are further supported by a GIA certificate for quality and authenticity. 

The GIA certificate specifies the key distinctions of a diamond: shape, measurements, proportions and grading results for the 4 C’s (carat weight, colour, clarity and cut). Additional grading information that establishes the full depth of a diamond’s sophistication includes the finish (polish, symmetry and fluorescence) and clarity characteristics.

The GIA certificate is the strongest assurance that clients should begin with as they make safe and considered investments.
