The Foundation of
Scientific
Trust.
G-ID Gemmological Laboratories was established to deliver independent, science-driven gemstone identification and analysis, underpinned by transparency, rigour, and a commitment to advancing the field.
Born from Scientific Conviction.
G-ID Gemmological Laboratories was founded with a singular mission: to provide the gemstone trade with analytical results that are fully defensible, scientifically rigorous, and free from commercial influence.
Our laboratory combines world-class human expertise—master gemmologists with decades of field and research experience—with a comprehensive suite of advanced analytical instruments, including Raman spectroscopy, FTIR, UV-Vis-NIR, EDXRF, and photoluminescence systems.
Headquartered in Bangkok, Thailand—at the crossroads of the global gem trade—we serve clients across Southeast Asia, Europe, the Middle East, and North America, providing trusted identification, origin determination, and treatment detection services.
