Diamonds are formed in a layer between the Earth’s crust and its core, known as the mantle. It is not entirely certain how diamonds are formed, but scientists do know that they are made up of carbon atoms that combine under intense pressure to form crystals.
Diamonds come in several hues, with coloured diamonds being much more common than colourless ones. According to the Natural History Museum, colour is affected by how nitrogen is scattered throughout the stone.
Where in the world can you find coloured diamonds?
If you like pink diamonds, the best place to source one is from the Argyle Diamond Mine in northwest Australia. This remote mine is responsible for supplying 90 per cent of the world’s pink diamonds.
However, this only accounts for a tiny proportion of the diamonds that the mine produces.
Champagne brown diamonds are also found in this mine.
For those seeking orange diamond eternity rings, such as those from https://www.comparethediamond.com/diamond-eternity-rings, it’s useful to know that most of the world’s diamonds in this colour stem from Africa.

Expect to find blue and yellow diamonds from this part of the African continent.
