Fire
Fire is a key quality term used in diamond evaluation that refers to how a diamond splits white light into rainbow colors. When people say a diamond has good "fire," they mean it shows bright flashes of colorful light when moved. This is different from brightness or sparkle - think of it like a prism effect. Diamond cutters work to maximize this quality through precise cutting angles. The term often appears alongside other diamond quality terms like "brilliance" and "scintillation" in job descriptions and industry discussions.
