Diamond Grading Workshop

Diamonds have long been thought of as symbols of strength, prestige, and eternal love however, not all diamonds are created equal. Learn what factors determine the quality and value of nature’s most sought after gemstone.
This two-day practical workshop takes participants through the grading process used by gemmologists, jewellers and laboratories.

Who Should Take This Course

Students will also learn about common diamond imitations and how to distinguish them from natural diamonds.

What You’ll Receive
