Evaanta Diamond Grading Standards
Evaanta diamonds are examined by a minimum of four highly trained diamond graders and gemologists. At each step of a diamond’s evaluation, a more senior staff member independently grades the stone. To ensure impartial evaluations, the distribution of diamonds to graders is a completely random process.

Diamond Grading Report
Many consider this to be the blueprint of a diamond. Starting with the 4Cs – cut, clarity, color, 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. To verify a diamond’s quality before purchase, be sure to review its Diamond Grading Report or Diamond Dossier and the GemEx certificate if you are buying an Astor by Blue Nile™ diamond.
What to Look for in Certificate
Aside from your home, purchasing a diamond might be one of the biggest investments you make in your lifetime.
