Advanced Gemmology Seminars
The Advanced Gemmology Lab Classes are predominately hands-on labs. They are ideal for jewellers and gemmologists seeking to broaden or refine their diamond grading and gem identification skills. They also provide up-to-date information on new treatments and synthetics.
You will practise grading or identifying a variety of diamonds or coloured stones that feature different characteristics and that have been previously graded by the GIA Lab.
Identifying Synthetic Diamonds Lab
Through a combination of lecture and hands-on practice with a microscope, you'll learn how to identify HPHT-grown synthetic diamonds and separate them from natural diamonds.
You'll also gain greater insight into the identification of CVD-grown synthetic diamond.
You will learn how to easily separate synthetic moissanite and synthetic cubic zirconia from diamond.
