Chief Minister Shri Barkatullah Khan Inaugurating Gem Testing Laboratory, Jaipur on 12th August, 1972

Few Words on GTL…

Jaipur, over the years has been one of the main trade centres for gems & jewellery. As the market bloomed, many new gemstones, synthetics and treated products started flooding the market and hereafter, advanced and analytical methods of gem identification started to replace the traditional and standard methods. With the increase in awareness for the new simulants and synthetics, the traders all over the world started demanding the official authenticity certificates.   Hence, with the arduous efforts of few honourable members of this trade, Gem Testing Laboratory (GTL) came into existence in August 1972 under the Convenership of (Late) Padmashri Khailshanker Durlabhji, founder Chairman of the Gem & Jewellery Export Promotion Council.
