Report Check The International Institute of Diamond Grading & Research's experts issue comprehensive analyses that come in our Diamond Grading Report. This report contains all the information needed by a diamantaire to authenticate a diamond and its awarded grade. It includes a comprehensive study of the diamond's carat weight, colour, clarity and cut. An accurate diagram of the diamond's cut dimensions is also provided, with any inclusions plotted. We can issue a report for any unset, natural diamond with a carat weight of at least 0.14 and with a colour rating within the D-Z colour scale. We can also provide reports for fancy colour diamonds.
