Diffusion Treatment
Diffusion Treatment is a process used to enhance the color or appearance of gemstones. It involves heating gems to very high temperatures with certain elements to change their color or add special effects. Think of it like dyeing fabric, but for precious stones. This is important in the gemstone industry because treated gems are usually less valuable than natural ones, so professionals need to know how to identify them. When reviewing resumes in the gemology field, this term indicates experience with gem identification and treatment detection.
