Ruby and Sapphire are chemically very similar: both are corundum, only color differentiates them due to chromium in ruby and titanium in sapphire. The best ruby comes from Burma (Myanmar) and the best colour is “Pigeon Blood”, but stones of this quality are rare and very expensive. Thailand, Tanzania and Madagascar also produce these stones. Pale red colours are actually classified as pink sapphire. Rubies are “the investment” stone. Large crystals over five carats are very rare. Ruby it is 9/10 on Mohs Scale.
