What is a Diamond Grading Report?
A Diamond Grading Report documents the diamond's unique characteristics. Performed
by an independent gemological laboratory, the report examines and identifies the
4C's -cut, color, clarity, carat weight-plus
finish, fluorescence and symmetry. The gemologist may add comments for further identification.
How do I know that I am getting the same diamond I selected?
Each Diamond Grading Report is assigned a unique number that corresponds to the
stone and certifies its characteristics. To ensure proper identification, the Diamond
Grading Report will have a diagram that shows all the inclusions unique to the stone,
or in some cases, the diamond will be laser-inscribed with the number of the Diamond
Grading Report.
Who issues Diamond Grading Reports?
To ensure your peace of mind, we offer diamond grading reports issued only by the
two leading independent gemological laboratories, the
Gemological Institute of America (GIA) and the
American Gem Society (AGS). Both have received international recognition
for their high standards and ethics and are respected worldwide as premier research,
education, and gemological grading institutes.
The GIA produces a
full Diamond Grading Report, with a diagram of inclusions, for diamonds
over 99 points. A
Diamond Dossier® is an abbreviated version of the Diamond Grading Report
that does not contain a diagram of the stone. However, the report number is laser-inscribed
on the girdle of the diamond for identification.

What is the difference between an appraisal and a Diamond
Grading Report?
A Diamond Grading Report can be requested before making a purchase. However, it
does not list the estimated retail replacement value. The
appraisal is ordered after you make a purchase. It confirms the 4Cs, but
also includes the estimated retail replacement value.
What if I lose my original Diamond Grading Report?
The number assigned to the Diamond Grading Report is on file with the grading institution
that produced the report. Additional copies can be requested for a nominal fee.
