Ruby (Manik) is distinguished for its bright red colour, being the most famed and fabled red gemstone. Beside for its bright colour, it is a most desirable gem due to its hardness, durability, lustre, and rarity. Transparent rubies of large sizes are even rarer than Diamonds. Ruby is the red variety of the mineral Corundum. Sapphire, the other gem variety of Corundum, encompasses all colours of Corundum aside from red. In essence, Ruby is a red Sapphire, since Ruby and Sapphire are identical in all properties except for colour. However, because of the special allure and historical significance, Ruby has always been classified as an individual gemstone, and is never identified as a form of Sapphire (though some purplish-red colours may straddle the line of being classified as either Ruby or Sapphire).
