INTRODUCTION

Gem Testing Laboratory (GTL) Jaipur, a project of the Gem & Jewellery Export Promotion Council (GJEPC), was established on 12th August 1972, under the Convenership of (Late) Padmashri Khailshanker Durlabhji, founder Chairman of the Gem & Jewellery Export Promotion Council. GTL is one of the older laboratories of the world which offers gemmological services to both domestic as well as overseas clients. During the course of time and changing technology, various services and features of GTL identification reports have been upgraded continuously.

The main functions of GTL Jaipur are gemstone certification along with research & development of techniques for identification of new gem materials, synthetics and treatments. The results of R&D are shared with the world through participating in conferences and publications in various trade and gemmological journals. GTL also acts as an information centre for various research institutions, government departments, etc.

At GTL Jaipur, the strictest of guidelines are followed to ensure the authenticity of gemstones and possible treatments in the most scientific and reproducible manner through combination of state-of-art analytical techniques and extensive practical skills in interpreting gemmological data. This not only provides proper disclosure of the stone, but also ensures public trust in gems and jewellery by preserving the highest standards of integrity, knowledge and expertise.

A Lab Information Circular (LIC) is circulated quarterly featuring latest gem news, research and gem related articles.

GTL is administered by the Technical & Education Sub-Committee (Jaipur) comprising of six members who meet regularly to discuss the general policy and direction of the laboratory.
