👉 Gemmology is a branch of physics that deals with the properties and behavior of materials, especially those made from minerals or other crystalline substances. It involves studying the interactions between atoms within these materials, which can lead to understanding of their physical properties such as elasticity, thermal conductivity, and magnetic properties. The term "gemmology" was first coined in the 19th century by British physicist Sir Robert Hooke, who identified a phenomenon that could be explained using the principles of crystallog
