WebJan 6, 2024 · A diamond’s sparkle is largely thanks to two qualities: brilliance and fire. “Brilliance” is a specific term describing a gemstone’s ability to return white light. It’s measured by the refractive index; a higher refractive index indicates a greater amount of white light reflected. WebThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as. v = c / n (1) where. v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index.
