Pushing the Polariscope
Alan Hodgkinson, FGA, DGA
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
