Who We Are

It was in the year 1965, some of the young, enthusiastic and far sighted gem traders met in an old office room in Zaveri Bazaar Bombay to discuss and give shape to their dream of setting up a gemmological institute in the country. They were none other than Shri Kirtilal K. Doshi, Shri Rajendrakumar A. Shah, Late Shri Himmatbhai C. Jhaveri, Shri Padmakant H. Jhaveri and Shri Pravin M. Nanavati. Thanks to their untiring efforts over the next six years, resulting the Gemmological Institute of India was born on 12th April 1971. The Gemmological Institute of India (GII) was established under the aegis of the Gem & Jewellery Exporters’ Association, Mumbai. The institute is registered as a non-profit Public Charitable Trust.
