Testimonials

I had a very enriching experience with for a month long, accelerated Polished Diamonds Graduate course. I do believe that very practical skills were taught which included pricing of the diamonds as loose stones as well as set in jewellery. I found that I was more confident in estimating a piece of jewellery in entirety and that too at the current market prices. It wasn’t bookish. I highly recommend this or any other course with J. K. Diamonds for even a novice in the field.

Being the 7th person from my family learning about diamonds was a mind blowing experience. My father did the course here 21 years ago, later my uncles and several employees. Now it’s the 2nd generation’s turn to enter business. The journey has been outstanding. Learnt well, scored well. Thank you so much!
