  • GIA debuts its first “Diamond Grading Lab Class” in Colombo, an important centre for gemstones. The five-day diamond course teaches both technical and practical ways to observe and evaluate diamond quality, and the basics of the famous GIA-created 4Cs (colour, clarity, cut and carat weight) of diamond quality. A majority of participants come from the jewellery industry. To learn more about GIA’s Diamond Grading Lab Class, visit http://www.giaindia.in/colombo-diamond-grading/
