What is Diamond Certification?

Independent certification is how you can be sure that you're getting a quality diamond that’s accurately graded without bias. To verify a diamond's quality before purchase, be sure to review its Diamond Grading Report.

The Difference Between Diamond Grading Reports And Diamond Dossiers®

Aside from your home, purchasing a diamond might be one of the biggest investments you make in your lifetime. That’s why diamond grading (a.k.a certification) is so important. The two main reports issued by the GIA are the Diamond Grading Report and the Diamond Dossier®. And, while similar, there are important distinctions.

• Diamond Grading Report: Many consider this to be the blueprint of a diamond. Starting with the 4Cs – cut, clarity, colour, and carat – the report includes precise measurements and shape, as well as a plot or map of the individual diamond’s characteristics. The diamond grading report will also note if the diamond has a girdle inscription, and will describe important characteristics beyond the clarity grade.
• Diamond Dossier®: This dossier offers the same grading information as the Diamond Grading Report, minus the plotted diagram. To prove authenticity, the dossier also includes the laser inscription number on the diamond’s girdle.
