Basic Gemmology

The Basic Gemmology course, developed by the WGF (World Gem Foundation), is largely devoted to the various instruments used to identify gemstones, as well as their principles of operation.

Many topics are covered in this course: the chemistry of gemstones, their physical and optical properties as well as notions of crystallography, light absorption, spectroscope, refraction and reflection, refractometer, optical character and sign, dispersion, reflectometer, polarized light, polariscope, pleochroism, dichroscope, colour filters, density, luminescence, thermal conductivity, and finally the microscope and loupe.

A great introduction to the world of gemmology!
