How do I know that a "stone" is a real diamond and not a fake? Why are diamonds considered so special and precious? What does VVS1, F or LC actually mean? Why is there such a price difference possible between two diamonds of the same size?
Our highly skilled and experienced lecturers will guide you through the fascinating world of diamonds. You will study the 4C’s: Carat, Colour, Clarity and Cut, determining the quality of a stone and as such the price. You will learn how to detect the most common simulants, and you will be able to work with the best microscope in the world and other gemmological equipment. At the same time, you will develop impeccable grading skills.
Our courses are a perfect balance between theoretical knowledge and practical skills.
