Al2O3.Corundum is called Sapphire except red Sapphire which is called Ruby. The word sapphire comes from the Greek word for blue, sapphirus. Only a few hundredths of a percent of iron and titanium can cause the colour, and the more iron the corundum contains, the darker the blue. A rare sapphire is a Padparadscha which is a pinky peach colour, found in Sri Lanka. The best shade of red for a Ruby is Pigeon Blood Red. Ruby can be any shade of red up to almost pink.
