Gem Identification 

with Teresa Polly

at Wildacres September

Class Description


The course will be an Introduction to Gem ID.  We will cover how to use a microscope, loupe, refractometer, polariscope, dicroscope, spectrascope and specific gravity set up to help identify stones.  We will start with basic mineral identification.  We will cover typical stone inclusions and how to tell natural stones from lab created stones.  I will have a set of tools and stones to share but please feel free to bring your own.  If you have stones you would like to ID we can work on those for show and tell.
