What will I learn ?

Is it a natural or synthetic? Learn how to scientifically identify natural diamonds, synthetics, imitations and detect treatments. In this intensive one-week course, SSEF provides exclusive insights into advanced diamond testing techniques. Acquire practical skills in a fully equipped mobile gemmological laboratory, using scientific spectroscopic methods and exploring portable analytical testing methods such as: FTIR spectrometry, UV-VIS spectrometry, Raman microspectrometry, fluorescence imaging and other cutting-edge approaches. Learn from highly experienced gemmologists and develop critical thinking skills that will benefit you in your professional career.

Who is this course for?

Industry professionals and gemmologists who want to gain insights into advanced diamond testing in a fully equipped laboratory and deepen their scientific skills.

Course structure

Main topics covered in this course include: Identification of diamonds as well as the most common spectroscopic characteristics of synthetics and treatments. Advanced portable analytical methods such as, but not limited to: FTIR spectrometry, UV-VIS spectrometry, Raman microspectrometry, fluorescence imaging. Critical thinking.

This course, taught by world-leading gemmologists, is designed in two parts: theory and hands-on training using gemmological instruments and samples from a large stones collection for study. Small groups guarantee intensive training and dynamic dialogue.

Aim of this course

The goals of this course are: i) to introduce students to portable spectroscopic instruments used to solve common gemmological problems, ii) to be aware of how to interpret and think critically about results, and iii) to be aware that there are limitations to the instruments and interpretations of data that can be made.

At the end of this course, students should be able to: i) Identify diamonds, ii) identify the most common spectroscopic characteristics of the most common synthetic diamonds, iii) identify the most common spectroscopic characteristics of the most common treatments, iiii) think critically about results and be aware of how to interpret results.

Long-term benefits

In this course you will be able to develop practical skills with scientific spectroscopic methods and gain theoretical insights into advanced portable analytical test methods. In particular, you will be trained to critically interpret test results.
