Gem Identification Lab Class

Lab class description

Practice the same time-tested procedures and identification skills used by the Institute’s renowned gemmological experts. Tools used include a microscope, a refractometer with polarising 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, a pinpoint incandescent light source and a colour 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. If you are unsure, contact your doctor for advice. Make sure you read the Student Notification of Classroom Chemical Usage.
