Overview
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).
This course enables you to obtain in-depth knowledge on the classification of all the different varieties of gemstones. You will learn to identify treated and synthetic gems and you will practice with a lot of actual gems to develop your identification skills.
You will be able to examine optical and physical properties of rare and uncommon gem varieties. Our lecturers will initiate you in a detailed analysis of natural gems, focusing on the origin of rubies, sapphires and emeralds. If you pass the theoretical and practical test you will be the proud owner of an HRD Antwerp Gemmologist diploma.
