The full name of our laboratory is GEMMOLOGICAL LABORATORY(THAILAND)and GLT for short.With the appearance of new gem sources and gemstone types and new treatment processes and synthetic gemstones, the public relies on GLT to know the identity and quality of the stones they love. Continued breakthroughs in research ensures the public’s trust in the gem industry and offers gem aficionados everywhere deeper insight into gem.
GLT research has focused on four main areas:
1.The identification of high-quality gemstones , and the determination of origin for gems derived
2.The identification of gemstone imitations, synthetics, and gem treatments.
