Refractive index aquamarine

WebThe refractive indices lie between 1.580 and 1.590 for the ordinary ray and the double refraction varies between 0.008 and 0.009. A few pink beryls (those with lower density) have refractive indices only a little higher that that of aquamarine. Some colourless beryl (rich in caesium) also have this higher density and indices of refraction.
