الوصف

The gemstones in the corundum group consist of pure aluminium oxide which crystallised into wonderful gemstones a long time ago as a result of pressure and heat at a great depth. The presence of small amounts of other elements, especially iron and chrome, are responsible for the colouring, turning a crystal that was basically white into a blue, red, yellow, pink or greenish sapphire. However, this does not mean that every corundum is also a sapphire. For centuries there were differences of opinion among the specialists as to which stones deserved to be called sapphires. Finally, it was agreed that the ruby-red ones, coloured by chrome, should be called 'rubies' and all those which were not ruby-red 'sapphires'.
