Brilliance, or brightness, refers to the intensity of light emitted or reflected by an object. It is often measured in units such as lumens or candelas, which quantify how much light is produced. Brilliance can be influenced by factors like the surface texture of an object and the angle of light hitting it. In the context of colors, brilliance can also describe the vividness or saturation of a hue. For example, a diamond exhibits high brilliance due to its ability to reflect and refract light, creating a sparkling effect. This quality makes certain materials, like gold or silver, particularly desirable in jewelry.
