An introduction to Sapphires and Rubies
Sapphires and Rubies are both precious gemstones that derive from the mineral Corundum.
They are the third hardest mineral on the Moh’s hardness scale, behind Diamonds and Moissanite.
Rubies and Sapphires are identical in composition, the only difference being impurities which produce their colour.
A Ruby contains chromium which produces the Red colour they’re famous for. Rubies can vary in colour from dark red to pink / purplish colours with varying saturation.
Sapphires get their colour from traces of iron, nickel and titanium. These trace elements produce Sapphires in a multitude of colours including Blue, Green, Pink, Orange, Yellow and Black. Colourless Sapphires are sometimes used as Diamond substitutes in jewellery.
Pink coloured Corundum may be referred to as Sapphires or Rubies, depending on their origin.
The most valuable Sapphire colour is Blue, however the quality of the gem is equally important.
Sapphires that display two or more colours in the one stone are referred to as Particoloured Sapphires. Sapphires from Australia are often Particoloured making them more unique for use in jewellery
Australia produces a large percentage of the World’s Sapphires and they are mined in Central Queensland and Northern New South Wales.
