GIA Sessions at the Atlanta Jewelry Show  

Course: GIA Gem Identification Lab Session

In this session, students should expect to practice the same time-tested procedures and identification skills used by the Institute’s renowned gemological experts. Tools used include a microscope, a refractometer with polarizing filter and a removable magnifying eyepiece, refractive index (RI) liquid, a polariscope with an optic figure sphere, a dichroscope, a table model prism spectroscope, a handheld spectroscope and a loupe. Students use these instruments to practice identifying natural and laboratory-grown gemstones, imitations and assembled stones. Along with this hands-on training, your instructors will carefully demonstrate key tests and coach you in quick, effective testing procedures. Students must pass an instrumentation exam to complete the class successfully. Once you have completed the class, you will keep a lab manual, a gem cloth, pinpoint incandescent light source and a color grading card.
