Diamond Grading Lab Class

Lab class description

Through a unique combination of hands-on training, one-to-one coaching and multimedia, the Diamond Grading lab class explores how to grade diamonds consistently and accurately using a modern gem microscope and a loupe. Students study GIA’s International Diamond Grading System™, explore time-saving shortcuts to determine a variety of grading factors and are introduced to ways of reading a GIA Diamond Grading Report. You will spend more than 16 hours practicing grading techniques on diamonds that have been carefully selected and graded by GIA. In the process, you will learn how to recognise the most common diamond features. Students must pass a two-stone practical exam to complete the class successfully. Once you have completed the class, you will keep a lab manual, a pointer probe, a gem cloth, a plotting pen set, a table gauge, a crown angle card and a colour grading card.
