Discover the fascinating world of gems and precious stones with our Advanced Gemology Course . This comprehensive 35-hour program is designed for those who wish to develop an in-depth understanding of gems, their physical properties, and appraisal techniques.
Course Program
• Fundamentals of Light : Study of monorefraction and birefraction, mono and birefringent gems and the concept of the refractive index, with practical exercises to detect the refractive index with the refractometer.
• Characteristics of Colored Gems : Exploration of birefringence and use of the polariscope, observation of fluorescence, and techniques for calculating weight and size.
• Gem Cuts : Analysis of the main cuts and observation with 10X lens and microscope for an accurate evaluation.
• Physical Properties of Gemstones : Evaluation of hardness, brittleness, fracture, toughness, brittleness, brilliance and dispersion, with demonstrations of the use of the UV lamp to analyze fluorescence.
• Inclusions and Internal Structure : Types of inclusions in gems, use of the microscope and understanding synthetic minerals, imitations and composite gems.
• Terminology and Correctness : An introduction to gemological terminology to avoid common misunderstandings and incorrect terminology in the gem trade.
Practical Exercises and Instrumentation
Students will have the opportunity to work with genuine gemstones and imitations of corundum and beryl (rubies, sapphires, emeralds and aquamarines). They will learn to use specialist instruments such as the polariscope, refractometer, 10X loupe, Leveridge caliper and microscope, consolidating analysis and evaluation techniques.
Exam and Certification
At the end of the course, students will take a written test and a practical test for the analysis of five stones. Upon passing the exam, a certification diploma will be issued, recognizing the acquired competence in the analysis and evaluation of gems.
