Sapphire, the story

It is a very desirable gemstone due to its excellent colour, hardness, durability, and luster. In the gem trade, Sapphire without any colour prefix refers to the blue variety of the mineral Corundum.

However, the term Sapphire encompasses all other gem varieties and colours of Corundum as well, excluding Ruby, the red variety of Corundum, which has its own name since antiquity.
