Diamond Certification

Gemology laboratories such as the Gemological Institute of America have created a certificate of quality that can be issued for any diamond whose dimensions, color, clarity, symmetry, and more meet the standard. Here at ICONIC we believe in trust built on complete transparency and that is why we offer our clients the opportunity to get your gem carefully examined and graded by professionals.


A diamond certificate, also known as a diamond grading report, is a report created by a professional gemology laboratory. Trained gemologists measure, examine, and assess the diamond in order to produce an unbiased report. A certificate will include details of the diamond’s dimensions, color, clarity, symmetry, and more.

Some of the world’s most respected independent grading labs include the Gemological Institute of America (GIA) and the American Gem Society (AGS). Grading standards vary between labs, making it important to choose a lab known for its rigorous standards.

Diamond certificates give buyers confidence that what they are buying is as described. Assessing value, however, requires an appraisal. Appraisals are usually carried out for insurance purposes.


There are a lot of factors to take into account which will determine the value of a 1 carat diamond, including the cut, clarity, colour and shape of the stone. Prices currently vary from anything from $1,800 to in excess of $12,000.
GIA stands for Gemological Institute of America, and they are responsible for grading diamonds and offering certifications.
To get a diamond certified by the GIA, it must be sent to one of their official testing laboratories. They will perform an analysis of the stone, grade it, and issue a certificate. This certificate is sometimes referred to as a “diamond grading report”.
