Gemmology Foundation Lab Class

All Online Distance Learning (ODL) Gemmology Foundation students are required to attend our Gemmology Foundation lab class. This is to ensure they 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).

All on-site and ODL Foundation students are provided with a refractometer and light source, in addition to the standard study stones and portable instrument kit at the start of their course. This allows students to familiarise themselves with the instruments at home prior to the lab class, and complete some of the practical elements. Students should bring all course equipment and their workbook to the lab class.

Those working in any sector of the trade or anyone who has an interest in gemstones can take this as a stand-alone course, either to learn about handling gems or to enhance existing skills. Gemmology Foundation students are required to take this course as part of their assessment.
This course is only for students who are studying our Gemmology Foundation course.
