Items of significant value typically come with important documentation – houses, vehicles, even purebred pets. But what about something as important as a diamond?

The most widely used and recognized documentation for verifying a diamond’s quality and authenticity is a GIA Diamond Grading Report™ or GIA Diamond Dossier®.

GIA reports provide an impartial scientific assessment of a diamond’s 4 Cs (cut, color, clarity, and carat weight), based on the International Diamond Grading System™, the standard GIA developed more than 50 years ago and today considered the universal language for describing diamond quality.

While a number of laboratories issue similar reports, GIA reports have earned a preeminent reputation for unrivaled accuracy and integrity when assigning diamond grades.

Here are some of the reasons why:

• GIA operates under a set of core principles designed to protect the objectivity of every report issued
• GIA invests heavily in research, staff training and the latest technology to ensure its procedures reflect the most sophisticated understanding of gemstones and their treatments
• GIA tests every stone to determine whether it is a diamond and whether the diamond is natural or synthetic
• GIA tests every diamond for laser drilling, fracture filling, irradiation, high pressure/high temperature (HPHT) and chemical vapor deposition (CVD)
• As the world’s largest grading laboratory, GIA routinely encounters a wider variety of specimens than other labs. So when new treatments and synthetics enter the marketplace, GIA is there to develop new methods of detection and identification
• GIA has graded some of the world’s most famous diamonds, including the legendary Hope Diamond (45.52 carats) and the De Beers Centenary Diamond (273.85 carats)
