GEM 120 GEMMOLOGY II (Theory Course)
This theoretical course covers the physical and optical properties of gems such as refraction, reflection, gem crystallography, pleochroism, absorption spectra, etc. It explains the various instruments used in gem identification.
The textbook “Gemmology, 3rd edition, 2007″ by Peter G. Read follows closely the Gem-A preliminary syllabus exam requirements.
Peter Read has prepared answer sheets exclusively for C.I.G. students taking this course.
