Includes the full Diamonds Course, Colored Gemstones Course, Gemology Tools and Techniques Course and the Created and Treated Gemstones Course.

ISG Mini-Course Program

UPDATE ON FREE MINI-COURSE PROGRAM!

Due to the HUGE amount of internet traffic our offer created, we have had to limit our offer to one course per week. This is due to the huge number of students trying to take all of the free courses at once. We now offer one course per week.
 
Therefore, I have posted up the Introduction to Gemology course until April 2, free to all. On April 3 we will post the Diamond Foundations course, again free. And each 5 days we will post up another single mini-course for free. By posting one at a time on the other provider, we should be able to restart this free mini-course program.
 
The ISG Introduction to Gemology course is active and free on our sister website linked below. It will be up until April 2. After that, another free mini-course will be available.
 
I welcome your feedback, suggestions and recommendations.
