WebReflection is the amount of light that bounces off the surface of a gemstone and is returned to the eye. This is the “sparkle” of a gemstone. Refraction is how the gemstone bends the light in different directions, separating white light into its spectral colors. This is called dispersion, and is the “fire” of the gemstone.
