GIA Diamond Grading Report Provides Most Respected Diamond Analysis Items of significant value typically come with important documentation. Houses have deeds. Vehicles have titles and registration. Purebred pets have pedigree papers. And a college education is validated with a diploma. But what about something as valuable as a diamond? The answer is yes: independent support documentation is available for diamonds to verify their quality and provide positive identification.
The most widely used and recognized means of verifying a diamond’s quality is with a GIA Diamond Grading Report™, provided by the internationally recognized, nonprofit GIA (Gemological Institute of America).
A report from GIA provides an expert analysis of the quality of a diamond based on the 4Cs of diamond grading: color, cut, clarity and carat weight. The GIA Diamond Grading Report also includes a plotting diagram that depicts the diamond’s unique clarity characteristics, such as inclusions. In addition, since GIA is not affiliated with any commercial enterprise, the public is assured the world’s most impartial and accurate analysis of a diamond.
The GIA laboratory employs highly trained diamond graders, gemologists, and research technicians and scientists to ensure the highest caliber of analysis for every diamond submitted for grading. Some of the world’s most famous diamonds have been graded by GIA laboratory experts, including the legendary Hope Diamond (45.52 carats), the De Beers Centenary Diamond (273.85 carats) and the Taylor-Burton Diamond (69.42 carats).
GIA only grades unmounted diamonds, and the fee for services varies based on the weight of the diamond. For an additional fee, the unique GIA Report Registry number can be micro-laser inscribed onto the diamond’s girdle (thin outer edge).
