Diamond Grading

What Is a Diamond Grading Report?

A diamond grading report is a detailed certificate that provides an independent and professional assessment of your diamond’s quality and characteristics. Also known as a diamond grading certificate or diamond report, it includes a comprehensive evaluation of the 4Cs: cut, color, clarity, and carat weight. GII’s diamond grading report provides buyers, sellers, and jewelry professionals with authentic documentation of a diamond’s authenticity and value, essential for informed buying and selling decisions.

GII’s Diamond Grading Process

Our diamond grading report assessment follows international standards and includes detailed analysis of each of the 4Cs. The cut grade evaluates how well a diamond has been cut and shaped, the color grade assesses the presence of color, the clarity grade determines the presence of inclusions, and the carat weight measures the diamond’s size. Every diamond grading report issued by GII is backed by our expertise as India’s first SIRO-recognized gemological laboratory.

GII Diamond Reports give an accurate assessment of the 4C’s of a diamond i.e. cut, color, clarity and carat weight, according to strict international standards.
