Do diamonds sparkle or blinks

Diamonds are known for their sparkle, which is the result of their ability to refract and reflect light. When light enters a diamond, it bends and splits into various colors, creating a dazzling effect. This phenomenon is often referred to as "fire" and contributes to the overall brilliance of the diamond. Unlike blinking, which implies a quick, intermittent action, the sparkle of a diamond is a continuous display of light and color.
