When a lot of diamonds are received, they are graded as per the 4Cs of a diamond. A diamond assortment report issued by a SDI lab provides a detailed and objective analysis of a diamond’s characteristics. The report typically includes information on the diamond’s carat weight, cut, clarity, and color, as well as other important details such as fluorescence and Number of diamonds. This report is typically used by jewelers and buyers to ensure that they are purchasing a high quality diamond that meets their desired specifications. 

They are grouped based on the clients’ requirements. And based on their criteria, they are selected or rejected.
