Diamond Certification Reports

It is crucial when choosing a diamond to review the diamond certificate, also known as a
Diamond Grading Report. This report documents the internationally recognised characteristics
of a diamond, its carat weight, colour, clarity, cut.

A diamond certificate, also called a diamond grading report , diamond dossier ® or diamond
quality report , is a report created by a gemmologist, or gemmologists, who have scrutinized
the diamond and placed it under a microscope to analyse its dimensions, clarity, cut, colour,
finish, symmetry, and other characteristics.

Every loose diamond sold by Delphi Diamonds has been analyzed and graded by either
Gemological Institute of America (GIA)
Antwerp Diamond High Council (HRD)
American Gem Society Laboratories(AGS)

By request Australian:
Gem Studies Laboratory (GSL) - Bill Sechos, Chief Gemmologist, President of the Gemmological Association of Australia

These are some of the most respected laboratories in the diamond industry. These laboratories are known for having the most strict, consistent, and unbiased systems for grading diamonds. Diamonds that are accompanied by these grading reports are the most highly valued in the industry, as their quality is considered guaranteed.

Please note, diamond certificates do not give you a diamond's valuation - appraisals do.

Diamond certificates state a unique certificate number, diamond measurements, table size, total depth, crown angle, crown height, pavilion angle, pavilion depth, culet, girdle thickness, cut proportion, cut symmetry, polish rating and fluorescence.
