DU-GEMOLOGY (Institute of Gemology & Laboratory)

This is the best gemology channel in Hindi language, imparting knowledge about gems, Mr Uday Day is one of the best teacher I have ever come across, he knows very well how to communicate the subject to the general public and professionals as well. I had no background of jewelry or gem profession but the teaching style of Mr. Uday attracted me to learn something about the subject and he made gemology palatable to me and perhaps to the masses, humble regards to the great teacher of gemology.

Mr. Udit sir Most positive and humble personality I ever meet, god bless you with good health and happiness

मैं नेपाल से हु, मुझे इनका काम बहुत अच्छा लगा, काम करने का तरीका समझाने का तरीका बहुत अच्छा हैं (all the best sir for your future ️)

I got absolute bang on, to the point information from Mr. UDIT. No jeweler could tell me in detail these things that he told me. You can contact him about diamonds and precious stone consultancy without any hesitation.

I went for a diamond ring and necklace testing, all the tests were performed in front of me with soo much professionalism, delicacy & on the top Mr Uday's (owner) behaviour is amazing, he share's his knowledge.
Overall complete satisfaction, genuine and the best.
Thanks for wonderfull service.

Took a Diamond Grading and Valuation course here. The course was very well structured and excellently delivered. Also, the instructor and the staff are awesome!

Quality of web analysis clarification is unclear even after providing all inputs, like IGL's own certificate number, category etc.

One of the nicest, informative and rarely found channel in youtube.
A big shout out to you.

Hi friends, brother, Sisters all over GROUP members mr.udia sir is very honest, except in Daimand laboratories work.
.

Still recent times I used to wonder how all these things related to diamond marking, cutting and polishing are done. His videos are very educative and give everyone an idea, how all these are done. Keep it up.

बहुत अच्छा कार्यक्रम हॆ।परंतु कच्ची रत्ती के वजन‌में सुधार कर लें।ये 121 मिलीग्राम की होती हॆ।एक तोला मतलब 11.664 ग्राम में 12आने ऒर हर आने में‌ 6 रत्ती होती हॆ।
बाकी अपके सभी वीडियो अच्छे हॆ।धन्यवाद।
