  • Refractive Index (Brilliance)

    As light passes through an object, it has a tendency to bend as the speed of the light slows down. The amount of “bend” that a material yields when light passes through it is known as “refraction”. When light passes through a vacuum (nothing), it bends very little. This slight bending of light is used to compare how much a given gemstone bends light passing through it. This ratio is known as the gemstone’s “Refractive Index”. Gemstones with a higher refractive index are more brilliant than gemstones with lower refractive indexes. Most gemstones have refractive indexes noted as ranges instead of a single number. This is due to the Optic Character of the gemstone
