What is Diamond Certification?
Diamond certification, also known as a grading report, thoroughly evaluates a diamond's attributes, including size, clarity, color, polish, symmetry, and more. Expert gemologists meticulously examine each diamond using specialized tools to create an unbiased and precise certificate.
