Gemmology Basic

The study of gemmology investigates all the properties of precious stones. Students who delve into gemmology, find themselves in an exciting new world of observation and investigation of beauty and science. We train students to identify gemstones using specialized tools and instruments and will study different types of inclusions with the aid of a gemmological microscope. You will learn how to distinguish synthetic from natural gemstones (ruby, sapphire and emerald and other important varieties).
