The enchanting world of coloured diamonds is renowned for its captivating hues and extraordinary beauty when set on rings or jewlery. To evaluate and determine the quality of these remarkable gemstones, renowned gemological institutes such as the International Gemological Institute (IGI) and the Gemological Institute of America (GIA) have established rigorous grading systems.
