Shri Shyam Jagannathan, Development Commissioner (DC), SEEPZ-SEZ was invited to visit GII laboratories in BDB complex on 3rd October. He visited B tower lab and was highly impressed about the services as well as clarity with which they are provided to various customers for discriminating their diamonds. For a query on Kiosk charges, Shri Mehulbhai Shah, Vice President, BDB conveyed that charges amount to less than Rs. 4 per cart for star melees, which is the cheapest in the world. He interacted with customers and GII employees manning Kiosk.

DC then visited laboratory and saw 6 laser Raman microscope and other instruments. He was highly impressed and appreciated with the utilisation of high tech equipment in solving various tricky problems associated with characterisation of diamonds. He asked about radiation effects on diamonds and was curious to know the correlation of depth profile and role of radiation treatment on diamonds. He was very happy with logical explanation based on systematic measurement data. DC assured to support all activities that GII proposed to set up in SEEPZ-SEZ. At that juncture, Shri Anoopbhai Mehta, chairman, GII and President, BDP explained “ —- GII is one of the reliable institutes that has expertise is R&D and use of instruments and carry out focused R&D to solve various R&D issues. That is the reason why GII was invited a decade back to open its branch in BDB and serve G&J industry with its R&D, testing services and education programs. There is no doubt that GII will continue to contribute to R&D in the years to come. GII success is due to dedication of employees and trustees as well as faith by customers.—”
Shri Mehulbhai Shah, Shri Anupbhai Zaveri, Managing Trustee, GII and Shri Sandesh Mane, Head, GII labs in BDB besides Shri Anoopbhai Mehta, Chairman, GII represented GII and provided many a clarification.

1. Bhabha Atomic research centre (BARC) has organised a two day theme meeting on Strategic Planning for Research Reactor Utilization (RRU-2022) during 6-7 May 2022 at Anushakti nagar Mumbai and Dharmendrakumar Chauhan, Nanddeep Keer and Dr. AVR Reddy of GII participated. A research contribution was poster presented (by Dharmendrakumar and Nanddeep) and an invited talk was delivered by Dr. Reddy.
2. GII has developed a quantitative method to estimate the low levels of cubic zirconia in diamond powder by using EDXRF and validated using Neutron Activation Analysis. It was poster presented in the conference. It was well received.
3. Dr. AVR Reddy was invited to give a talk on future work on Utilization of research reactors in coloured gemstones and diamonds, and he presented some of the earlier work and possible work that can be carried out using reactor neutrons.
4. One of the Trustees, Shri. Shripalkumar Desai spoke in a panel discussion on the status of Neutron irradiations for quality improvement.







Outcome: The results of estimation of CZ, obtained by EDXRF and NAA methods are in reasonable agreement, as the difference is insignificant. EDXRF method can be used to quantify CZ in the binary systems of diamond Powder and coating of Zirconia. Presentations by other scientists and discussions with them during these two days are very useful.

Gemmological Institute of India, Mumbai and National Gem Testing Center, China has entered an historical agreement between them for development and promotion of various technical and trade related aspects connected to Diamond Industry which will be of mutual benefit to both the countries.
