How do professionals approach gem identification when faced with similar looking stones?  Having discovered the astonishing array of beautiful gems in the previous courses, and learning how to systematically test and analyze them in Gemmology 3, students now hone their gem identification skills by differentiating between stones that look the same.

Who Should Take This Course

Jewellery professionals and gem lovers alike will benefit from the extensive hands-on gem observation and testing offered in Gemmology 4.

Prerequisites: Gemmology 3.

What You’ll Learn

Students will apply their gem identification skills when faced with gems of similar colour and appearances.  In EGM’s well-equipped classroom, students will observe and test carefully selected specimens from the vast collection of gemstones.  The course focuses on a series of gemstones grouped by colour, and students must differentiate and identify each individual gem material.

What You’ll Receive

All students will receive detailed course notes with a list of gemstone properties and identifying features that will serve as a valuable reference for the future.  Students who successfully complete the course and pass the final exam will receive an attestation from EGM.
