Gemmology is the scientific study of gemstones, focusing on their identification, evaluation, and classification through optical and physical testing methods. With the help of specialized instruments, experts analyze characteristics such as color, clarity, refractive index, and spectral behavior to distinguish natural stones from synthetics or imitations.

The careful handling and methodical examination of each gem ensure reliable results and support accurate grading. As a discipline, gemmology combines scientific precision with practical expertise to guarantee trustworthy assessments in trade, laboratories, and appraisal work.
