Their physical and optical properties and chemical contents show remarkable differences. Spectral analysis shows that the color of ruby is caused by the color-causing elements nickel , chromium and iron , whereas the color of sapphire by the color-causing elements iron and titanium. The variations of their color shad ing and tone result mainly from the iron content and Fe3 + / Fe2 + ratio.
