This advanced training course is an intense gemmological programme that offers a detailed hands-on approach to identifying treatment and origin of ruby, sapphire and emerald. The course syllabus is built up in a modular structure.
We demonstrate the possibilities and restrictions of treatment detection and origin determination of corundum and emerald. Participants should subsequently be able to recognize the most characteristic internal features in untreated and treated stones of different origins.
