Gemology, also known as gemmology, is a branch of geology that deals with the study of gemstones. These precious and semi-precious stones have captured the fascination of humans for centuries and continue to do so even today. Gemology is a multidisciplinary field that combines elements of geology, mineralogy, chemistry, and physics to study and understand gemstones, their properties, origins, and uses. The study of gemology begins with the identification and classification of gemstones.
