Coloured Gemstones Grading 1

The Coloured Gemstones Grading 1 course, developed by the WGF (World Gem Foundation), is devoted to the practical gradation of coloured gemstones.

This five-day workshop includes practical instruction on how to access the hue, tone and saturation of coloured gemstones using three popular colour grading systems (Gemological Institute of America, GemDialogue and World of Color) and how to grade pearls, jadeite and opals.

This course will help you to define which colour is the best according to the gemstone.
