All necessary major equipment is provided, but students should bring their own pocket instruments (which are available at reasonable cost on-site). Required course textbook may purchased separately. Class size is limited to a maximum of 8 students.

Pre Exam Lab


sapphireAn optional 5-day Pre-Examination Lab Course is offered in Toronto prior to each examination session, based on demand. This lab session in gem identification and instrument use is primarily intended for CGA registered students who wish extra practice in preparation for the professional-level practical examination, but other qualified individuals may be accepted. 

The focus of the week is to give students as many gemstones as possible for viewing and identification, to become comfortable with the instruments and to devote extra time and support to areas of weak understanding. A qualified gemmologist with teaching experience will supervise.

Schedule: 5-days, 9:00 am - 4:00 pm
Next Session: January 8 - January 12, 2018 
 CGA student $675.00/non-student $845.00
