Gem Identification Class
LAB CLASS DESCRIPTION
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 class manual, a gem cloth, pinpoint incandescent light source and a color grading card.
Rl liquid is used in this class. You may need to exercise special precautions if you are pregnant, if you have certain medical conditions and/or if you have sensitivity or are allergic to this chemical.
