It is rare to find a laboratory with such high ethical standards, and their commitment to honesty and scientific truth is unshakable. Since 2000, they have provided the gemstone community with accurate identification and valuable consultancy. Jabbar Sir is a legend in the field, and his reputation for integrity is well-deserved. A 5-star experience every time.

The expertise at this Institute is world-class. Seeing Jabbar Sir identify stones with such mastery using a 10x loupe shows the power of 45 years of experience. The lab doesn't just give you a report; they give you a deep understanding of the gemstone. Professional, highly knowledgeable, and deeply respected in the industry. I wouldn't go anywhere else for gemstone testing or education.

Hi,

I’m Akshat.

Jabbar Sir is a well-known expert in gemstone testing and has over 45 years of experience in teaching coloured gemstones. I learned about his institution through a colleague who is a gemstone trader in Mumbai.

The course offers comprehensive knowledge on identifying a wide range of gemstones. Its unique strength lies in teaching identification using only a 10x loupe. Jabbar Sir is a trusted name in the gem and diamond testing field.

The institute provides excellent hands-on training, with access to over 200 varieties of gemstones for practical learning. Overall, it has been an excellent learning experience, and I highly recommend it to anyone interested in gemstones.

I know Jabbar bhai for the last 30 years and he is the best person I know ex-faculty of GII. His experience is very vast and he has indepth knowledge of Gemstones & Diamonds. He is also a gem cutter so he knows all parameters of gems and their properties. His work is really appreciateable. Sabse purana lab hai zaveri bazaar ka aur inke jesa consultancy aur guide gemstones aur Diamonds Mai koe nahi De sakta hai.
