Program Overview

The Gemmology program teaches you to analyze and classify a wide variety of gem materials, both natural and artificially created. The program focuses on analyzing chemical and physical characteristics of gem and gem-like materials, and identifying different gems. The gem materials are classified into categories according to their desirable characteristics, which eventually determine the value of the gems. To accomplish the identification and classification, you use a number of specially designed instruments, such as microscopes, spectroscopes, refractometers and polariscopes, on real gem materials.

Visual acuity and accurate colour rendition are essential traits for success in Gemmology.

Refractive Index liquid (RI liquid), which contains diiodomethane, is a commonly used chemical in Gemmology practice. If you are pregnant, have certain medical conditions or are sensitive to RI liquid, please consult with your physician for advice before you attend this program, as you will be exposed to RI liquid in Gemmology lab work.
