A message from Tanja


What our students have to say?

  • The JDMIS environment truly felt comfortable to me when I joined and I found everyone to be very helpful. Tanja Sadow is a very professional instructor who shares knowledge and provides education in Gems and Jewellery arts. With JDMIS, I will continue my Jewellery Design course in the future. I would like to thank JDMIS for providing me with a professional education and making me feel more confident about my career choice.

    - Grace E. (Singapore)

  • The only school in Singapore that provides very good professional jewellery learning.

    - Sin Yu C. (Singapore)

  • Really well-organised school with well-planned classes on and offline, the best intructors and most importantly, super fun and enjoyable! Such a great school deserves to have continued funding so that more students can benefit and grow the jewellery industry in Singapore which still has so much potential.

    - Calvin Z. (Singapore)

  • 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.

    Great skills taught by great instructors! (I) may create new pieces of jewellery for friends and families, and probably make a jewellery line under my name.
