Sample answer
“In my training, I learned to grade diamonds based on the 4 Cs. For example, I assess the carat weight using a precise scale, then examine the cut under a microscope to evaluate its symmetry and proportions. I check color by comparing it against master stones, and for clarity, I look for inclusions and blemishes using a loupe. Following GIA standards ensures my grading is consistent and accurate, which is critical in maintaining the quality of our gemstones.”
