Introduction Moissanite earrings are renowned for their brilliance, but what exactly gives them that mesmerizing fire and sparkle? Here?s everything you need to know about the dazzling qualities of moissanite. Refractive Index Moissanite has a refractive index of 2.65?2.69, which is higher than that of diamonds. This means that moissanite bends light more effectively, resulting in greater sparkle. Dispersion and Fire Moissanite?s dispersion rate is 0.104, compared to a diamond?s 0.044. This allows moissanite to separate light into its spectral colors, producing a fiery, rainbow-like effect that?s captivating to the eye. Conclusion The fire and sparkle of moissanite earrings are unmatched, thanks to their high refractive index and dispersion. If you?re looking for earrings that dazzle in every light, moissanite is the perfect choice.
