Lab Classes

All Online Distance Learning (ODL) students on Gem-A’s core courses are required to attend a lab class for practical tuition. This is to ensure our students can use their equipment safely and correctly, and are able to handle a range of stones beyond those supplied on the course. Students can attend a lab class in the UK, USA or Japan, or they can arrange to take a class with one of Gem-A's Practical Providers (GAPP) or Accredited Teaching Centre (ATC).

It is important that all students gain experience and guidance in the practical aspects of gem testing, as this is essential to understand the theoretical aspects of the courses and is an integral part of studying gemmology. The lab class provides ODL students with the opportunity to familiarise themselves with a wide range of gem materials and gem testing techniques that will enable them to accurately test and identify gem materials.

You can apply to take the Diamond Practical as a stand-alone short course.
