Diamond Grading

Diamond grading is the process of evaluating and assigning a grade or quality score to a diamond based on its characteristics and attributes, such as cut, color, clarity, and carat weight. This information is used to determine a diamond’s value and provide a standardized way of comparing diamonds to each other. The most widely recognized diamond grading system is the 4Cs of Diamond Grading, established by the Gemological Institute of America (GIA).
