If you have time and interest, you can apply. IGI is an excellent jewelry college, and the courses of basic theoretical knowledge may be generally boring and complicated. IGI school has a lot of theoretical knowledge and strict practical operation, and what you have learned is more practical. Practice classes will be much more than theory classes, and it will be very interesting to learn. You can watch all kinds of original gems and crystals every day. If you study diamond grading, I look at diamonds with a magnifying glass almost every day, and mark the position of diamond defects on the drawings every day, such as contrasting colors. Especially when you can score diamonds quickly and accurately and see the same answer, I will have a strong sense of accomplishment. Anyway, as far as I'm concerned, I think the IGI qualification course is really interesting.
