Laboratory Identification

The main objectives of laboratory gemmological analysis are to certify the nature of a gem by identifying the numerous natural and synthetic gems, to detect the presence of treatment, to determine the origin of the colour, to classify diamonds, or to have a reliable opinion of the geographical and geological origin (theoretical aspect) of a sample.

The objective of this course is to enable participants with a sound knowledge of gemmology or jewellery to understand the procedures of scientific analysis through the joint use of classical gemmological tools and advanced method instruments.

The student will receive theoretical instruction (analysis procedures, presentation of laboratory instruments, their operation, preparation of a laboratory report) and practical instruction (use and handling of instruments, identification of gems).

The class size is reduced to 4 students: the learning takes place directly at the LLG Gemmology Laboratory, and each student has access to each of the instruments of the LLG laboratory and its partners.

Who Should Take This Course

It is necessary to hold a certificate or diploma in gemmology.
