Diamond Certification
A diamond certification should be prepared by an expert gemologist. The grading reports describe the key characteristics of a diamond, providing you with a scientific blueprint. It is important to have the diamond certification provided by an independent grading laboratory and not by the diamond retailers themselves. Some in-house diamond certificates can be biased as the retailers can lower the standards while doing their own grading.
Modern Diamond grading laboratories use the latest technology to evaluate the characteristics of diamonds. Most laboratories use their own grading system and may show different reports from one another.
