gemology
Study of gems
Gemology is the scientific study of gemstones—their identification, grading, and evaluation.
A gemologist examines stones for qualities like cut, clarity, color, and carat weight, and distinguishes natural gems from synthetics or imitations.
The field combines mineralogy with practical expertise for the jewelry trade: She studied gemology before opening her shop.
