The World's Most Brilliant Gem.
With a refractive index of 2.65-2.69, moissanite exhibits more brilliance than diamond. And thanks to a dispersion that’s 2.4 times higher than diamond, moissanite bends light into mesmerizing rainbow flashes of fire… more than twice as much as diamond, ruby, emerald, or sapphire. By day and by night, moissanite’s conspicuous brilliance is spectacular.
