What did our graduates say?

The instructors at JDMIS are very professional and provide good quality materials.
Yvonne M. (Germany)
Very clear step-by-step on the techniques and skills and lots of useful and revelant content.
Li Ling (Singapore)
Ms. Tanja Sadow is a great teacher and one can feel very comfortable with her and it's great fun in class.
N.B. (France)
I have recommended JDMIS to my friends so many times over the years, I can't remember how many times I've talked about it now. I always say it's not just fun but extremely practical in real life.
Stephanie T. (Singapore)
Excellent! I enjoyed this immensely. Time whizzed past without me realizing it! I would most definitely tell my friends about JDMIS and I hope to come back and attend more courses in the near future.
C.R. (Brazil)
If you are thinking of joining the jewellery industry, attend JDMIS courses. Both courses that I have attended are useful for me, (especially) for my new jewellery business.
