GIA revolutionized the diamond industry in 1955 with
its Diamond Grading Report
. Based on the 4Cs of diamonds and International
Diamond Grading System™, both of which GIA created, the grading
report provides a comprehensive analysis of quality and authenticity
for diamonds in the D-to-Z color range. It contains information on diamond
shape and cutting style, measurements and weight, proportions and finish
along with grades for clarity, color, and cut. In addition, it identifies
any known treatments. While a number of laboratories issue similar reports,
the GIA Diamond Grading Report has earned a reputation for unrivaled
accuracy and integrity when assigning diamond grades.
For stones between 0.15 and 1.99 carats, GIA offers the Diamond Dossier®
It contains the same information found on the traditional diamond grading
report but in a more compact format. As an added security measure, the
Diamond Dossier® includes a laser inscription of the identification
number. A professional jeweler can arrange to have your diamond graded.
GIA’s laser inscription service can also be used for personal messages and anniversary dates. At the client's request, a diamond may be microscopically inscribed on its girdle with its unique GIA Report Number (referred to as the GIA Inscription Registry), a personal message, or other text, symbols, or logos. An inscription allows for easy identification of a diamond, a way to personalize the diamond, or serves as a form of branding for the diamond manufacturer or retailer.
