Production Certification
A diamond certificate, also called a diamond grading report, diamond dossier®, or diamond quality document, is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler抯 loupe, a microscope, and other industry tools. A completed certificate includes an analysis of the diamond抯 dimensions, clarity, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade on the report. Every loose diamond sold by Blue Nile has been analyzed and graded by either the Gemological Institute of America (GIA) or the American Gem Society Laboratories (AGSL). These two laboratories are among the most respected laboratories in the diamond industry, and are known for their consistency and unbiased diamond grading systems. Diamonds that are accompanied by these grading reports are the most highly valued in the industry. In addition to being graded by either the GIA or the AGSL, all Blue Nile Signature Collection diamonds are certified by GCAL. This additional certification provides a second independent and authoritative analysis of your diamond. GCAL also verifies that your diamond meets all of the demanding quality requirements of the Blue Nile Signature Collection.
