GIA Lab Sessions

The Midwest Jewelers Association is hosting the Diamond Grading Lab April 30 - May 4, 2019. The session is sponsored by Jewelers Mutual Insurance Co. in Neenah, WI where the class will be held. The session is limited to 15 participants.

The cost includes tuition, books, use of gems, materials, and facilitators fees. You are responsible for your travel, hotel charges (if using), and all meals. Jewelers Mutual has an on-site cafeteria for breakfast and lunch items that are priced moderately, and there are many fine restaurants nearby.

The Diamond Grading Lab Session is required for the GIA Graduate Gemologist diploma. You do not need to take the online class first.


Diamond Grading Lab Session
Through a unique combination of hands-on training, one-on-one coaching, and multimedia, the Diamond Grading lab session explores how to grade diamonds consistently and accurately using a modern gem microscope and a jeweler’s loupe. Students study GIA’s International Diamond Grading System™, explore time-saving shortcuts to determine a variety of grading factors, and are introduced to methods for reading a GIA Diamond Grading Report. You will spend more than 16 hours practicing grading techniques on diamonds that were carefully selected and graded by GIA. In the process, you will study how to recognize 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 color grading card.

Session duration: 5 days (35 clock hours)
