Today, often sophisticated equipment is needed in the identification of
gemstones and diamonds. One of the most underused and misused pieces of
equipment is the polariscope. In this enlightening presentation,
renowned Scottish gemologist, Alan Hodgkinson, will demonstrate
“Pushing  the Polariscope” for ease of determining optic figures,
identifying gemstones, distinguishing spectrums, and determining diamond
type. Learn to use the polariscope in ways GIA did not teach you.
