with Teresa Polly
at Wildacres September
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 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. If you have stones you would like to ID we can work on those for show and tell.
