Comprehensive Diamond Grading Reports

The cornerstone of our business is the grading report, meticulously crafted to provide an unbiased professional opinion. Every diamond is unique—formed by nature and polished by human skill. Our reports focus on the crucial "4 Cs" – Carat, Colour, Clarity, and Cut, offering a databank for every graded diamond. We guarantee impartiality by having a minimum of two graders examine each stone. Our modern technology, coupled with years of expertise, ensures the highest standards in our evaluations.

Our Diamond Reports offer a complete and in-depth look at your diamond's technical attributes, including Colour, Clarity, Carat Weight, Diameter, Depth, Crown Angle and Height, Pavilion Angle and Height, Culet Size, Culet off centre, Table size, Table off centre, Star Lower and Upper Girdle & Fluorescence. These reports feature detailed illustrations and markings, offering expanded data on your diamond's proportions. Designed for clarity, IDRC reports are straightforward and easy to understand.
