Coloured Gemstone Grading 1 Course in English French and Spanish
We have a very simple corporate philosophy. If a grading system is available in the marketplace, we include it in our courses. Our goal is to prepare you for the real world…..wherever that may take you.
In this five-day workshop, you will learn how to access the hue, tone and saturation of coloured gemstones using three popular colour grading systems (GIA, GemDialogue and World of Color) and how to grade pearls, jadeite and opals.
