Our coloured stone reports relate to price. The most important grade is the colour. We then deduct points for everything affecting the beauty of the stone from the colour grade until you reach the final grade which relates to price. If you look at the colour grade and the final grade is lower then there have been some deductions. For more info on the ICSL coloured stone grading system go to our website www.gemlab.co.za. The grades are in percentages.
