The labs are operated independently of retailers, dealers, and even the diamond minds, so they are able to provide an unbiased evaluation of a diamond. Each diamond is examined separately by a number of gemologists who then assign grades that are reliable, accurate, and consistent.

Based on the findings, the lab then issues a written report to accompany the diamonds. Diamond certifications and reports can vary among labs in terms of information and finer details.

Besides the all-important diamond certificate, if you are buying a diamond engagement ring, or any diamond jewelry for that matter, make sure your piece comes with a warranty.
