Diamond Grading and Identification

This intensive practical certificate course and examination is ideal for those who need a diamond practical qualification in a short period of time, or for those who simply wish to pursue the practical side of diamond grading. Identical to the practical section of the Gem-A Diamond Diploma examination, the Diamond Grading and Identification course fee includes the same diamond grading manual and instrument kit as provided in the Gem Diamond Diploma course, without the theory portion of the course.

Course times are 9:30 am to 5:00 pm each day. No prior diamond experience is required.
