 At the convocation function held on 1st October, 2016

Friends, I stand before you with a heart full of containment and satisfaction that the Gemological Institute of India has crossed over many milestones towards the fulfillment of dissemination of gemological knowledge and advancement of the Research studies related to Gem & Jewellery field in India.

Any Industry after certain stages of its development requires scientific foundation or knowledge base for its un-interrupted growth.

Today the Gem & Jewellery industry in India is one of the most modern industries using the highly sophisticated instruments and technology for manufacturing of gemstones and its identification.

This technological advancement was possible only because of the relentless efforts that have been put up by the industry organizations and educational institutions connected to the Gem & jewellery industry in India.

Since 1971 GII has been actively working to protect, support, promote and propagate the scientific developments and gemological education in the country.
The seed that was sawn by the visionaries in 1971 under the leadership of Shri KirtibhaiDoshiand others has grown into the gigantic tree that started yielding fruits today.

We are indebted and profoundly thank ShriKirtibhaiDoshi, ShriRajendrabhai A. Shah& other senior trustee for their pragmatic approach for scientific development and far sightedness in establishing the Gemological Institute of India, the very first school in gemology in the country.

Now it is the time for present Trust Board and the industry to carry forward the GII to further heights.

For this purpose we need the young talents who have graduated from the institutes like GII. Today it is the time the Industry needs more and more technocrats who are qualified and having commitment, dedication with an open and scientific band of mind.

The challenges the industry is facing today is different from that of yester years.
Synthetic diamonds is one amongst them. Treatment is yet another field where we need detailed study to differentiate natural from treated stones. Origin of gemstones plays an important role.

No doubt the gemstone business is still a very subjective one. The younger generations learn by experience and it is mostly handed over by hereditary manner. Nevertheless, that traditional knowledge of the dealer has to be supported by strong scientific foundation. Therefore we need to spread the knowledge of gemology across the country and around the globe. Gemology is a language we traders should be speaking throughout the world. It is a vehicle of communication.

I take this opportunity to congratulate the students who have graduated from GII and wish them good luck.

Friends, I would like to make an important announcement today.

Over the years GII services and certificates became very popular all over the Country because of the increasing support and co-operation and patronage given to GII by the Industry.

In recognition of this support the Board of Trustees of the GII has unanimously decided to institute an award to those Industry members who have been continuously motivating us and the spirit behind our services and success.

The award is named as “GII Star Mitra Award”.
We have divided the Awards in to 3 categories:

1. Gemstones
2. Jewellery and
3. Diamonds.

We have instituted 2 awards from each category for the top two partners.
We have decided to start this award from the financial year ending 31st March, 2016 and will be continuing forever. I believe in coming years the award would be become most sought after.

I take this opportunity to congratulate all the recipients of the awards.

I invite friends, patrons and associates of GII, particularly from the Gem Stone & Jewellery sector, actively involve themselves with GII activities for promotion of Trade.

I suggest we will introduce colour Gem focused Jewellery Designing programmes. GII will also look forward to partner with Jewellery Retailers in Ad-campaign as certifier.

Coming to the Research and Development activities of GII is concerned our team of GII scientist headed by Dr. M. D. Sastry is doing an exemplary job in taking care of the needs of the Indian industry specially addressing the recent advent of synthetic diamonds in the Indian market.

With the support of the Trade organization like Council, BDB, DEAL, MDMA etc. we are sure that the Indian industry could overcome the challenges that are coming up in the course of our onward journey.

I once again thank you all, especially my colleagues in the Trust Board for their valuable support and co-operation to me.
I also thank Dr. Lore Kiefert for accepting our invitation and grace the occasion with her presence.
I also thank Shri Rajiv Jain for accepting our invitation and grace the occasion.
I also place on record my sincere appreciation to all the staff of GII ably led by Mr. Ramchandran, Dr. Sastry, Mr. Das for their commitment and dedication to the responsibilities entrusted to them.

Thanking you once again,
Jai Hind.


Shri Rajiv Jain, Guest of Honor on the occasion addressed the gathering.

Shri Rajiv Jain was the former Chairman of the Council and he is the Chairman and Managing Director of Sambhav Gems Ltd., Jaipur. Shri Rajiv Jain appreciated the efforts made by GII in promoting the scientific aspects of gemstones by organizing such seminars and he appealed to the industry member to take advantage of the laboratory services offered by the Council’s laboratories. He also wanted the gem testing laboratories in India should work together and share their knowledge for the benefit of the industry.

I place on record my sincere thanks to my friends and colleague from the industry for their valuable and continued support and co-operation to GII.
I also thank the press for their unfailing support to our activities in the media regularly.


Instrument for immediate detection of Synthetic diamonds

Mumbai, 8th July 2016: To address the threat of undisclosed mixing of Synthetic diamonds with Natural Diamonds, the Gemmological Institute of India (GII), a project of GJEPC and co-sponsored by BDB has introduced a new instrument which immediately detects synthetic diamonds. The instrument which has been named as “Quick-Check”, has been designed by the in-house research team of the Gemmological Institute of India and Arotek.

Quick-Check takes only a few seconds to scan the ‘High Pressure High Temperature’ (HPHT) type IIb diamonds once they are loaded in the detection chamber of the instrument. The instrument is simple to use and does not need a highly qualified professional to operate, unlike the currently available diamond detection instruments, which are technical and scientific and hence complex in nature.

Quick-Check-Q-CHK-instrument

The instrument can detect HPHT diamonds in a few seconds.

Shri-Bakul-R-Mehta-Chairman-GII-addressing-the-gathering

Commenting on the induction of this instrument, Mr.Bakul Mehta, Chairman, Gemological Institute of India, said, We will now be able to detect HPHT Type IIb synthetic diamonds immediately and with absolute results, with the introduction of ‘Quick-Check’. This affordable device will be able to curtail the threat of mixing of synthetic diamonds in the market. This is so essential to maintain customer confidence. I invite Retailer and manufacturers to come forward and avail the benefits of this instrument.

Mr. Praveenshankar Pandya, Chairman, GJEPC, said, We wish to safeguard ourselves against any threat of illicit mixing of synthetics with natural diamonds. With the advent of this instrument, the industry will benefit the most as the detection of synthetic diamonds with this instrument will help supply of natural diamonds to flourish. I am very impressed with the ease of use and affordability of this instrument.


Mr. Russell Mehta, Vice Chairman, GJEPC, also said, This is a landmark achievement by Gemmological Institute of India. India is one of the largest hubs for diamond processing and this initiative will build more confidence in the trade circles.
