Formation & History Of Sapphire

The name sapphire is Greek for blue. Before the properties of the stone were discovered in the middle ages, the name sapphire was applied to various blue stones such as what is now called lapis lazuli.

Around the 1800s it was recognised that sapphire and ruby are gem varieties of the same mineral - Corundum. Corundum is a rock forming mineral which is the hardest after diamond.

Pure corundum is colourless, however the colours that are found in both ruby and sapphire are caused by small amounts of chemical impurities. The rich red of ruby is caused by chromium, whilst sapphire is the name given to all other colours of corundum which is caused by iron and titanium. These colours include blues, yellows, pinks, greens and more. Sapphire is more commonly associated with the colour blue.

Before the various variety of colours was given the name sapphire, they were given misleading names, such as "oriental topaz" and "oriental peridot".  

The main sapphire bearing rocks are marble, basalt or pegmatite. The most desired sapphires used to come from Kashmir, India, where the deposits were situated at a height of 16,500 ft in the Zaskar region. It is said the sapphires were of deep cornflower blue with a silky sheen.
