When you receive your diamond you will also receive its certificate. This is a quality analysis of your diamond and guarantee of the quality and value of that diamond. Though the 4Cs are commonly used as guides in diamond purchase, only experts in gemology can really evaluate a diamond based on these 4 characteristics. In grading a diamond, gemologists use highly sophisticated spectrometers and other high-tech equipment. Independent gemological laboratories issue a document containing the vital characteristics and the grading of the 4Cs.

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

Every loose diamond sold by this site has been analyzed and graded by a major independent grading lab such as Gemological Institute of America (GIA), American Gem Society Laboratories (AGSL) and the European Gemological Laboratory (EGL). They are 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.
