The presence of visible spectral colors in the gemstone is commonly known as the “fire” of the gemstone. Dispersion is a scientific comparison between the Refractive Indexes of two different wavelengths of light passing through the same material. How much “fire” the gemstone has is based on many different factors, including the refractive index of the material, the gemstone’s facet angles, the quality of the gemstone’s polish, the lighting used in the test and other factors.
