GEM IDENTIFICATION
Through instructor presentation, more than 17 hours of lab time, integrated multimedia presentations and exclusive hands-on practise, you learn the deductive reasoning system – a step-by-step procedure for simplifying gem identification and detecting synthetic and treated gems.
Gain experience by using professional gem-testing instruments.
In this predominately hands-on class, you work with about 60 species of gemstones to practise the same effective testing procedures and identification skills used by GIA's renowned gemmological experts.
Who can enrol?
