Laboratory Grown or Natural Diamond Short course

A one-day course on synthetic diamonds and diamond simulants given by
Jacinta Mainstone, including both theory and practical components using all the
tools you need to determine the type of diamond or simulant you examine and if
it needs a more complete diagnosis by advanced techniques.
You will have access on the day to instruments available on the market such
as:
Presidium Synthetic Diamond Screener II
Gemetrix PL Inspector
Presidium Diamond Tester
There will also be a demonstration of the Magilabs EXA Fluorescence
Spectrometer.
The workshop will also involve using standard Gemmological instruments, such
as polariscope, microscope, UV and Gemetrix Dove Diamond Inspector, to
investigate the differences in internal strain patterns in natural type I, CVD Lab
grown Type II, Plasmability CVD synthetic diamonds (as reported on by GIA in
Gems & Gemology 2025) and HPHT lab grown Type II diamonds and various
ultraviolet reactions to identify the different types of diamond and different
treatments
