So we all know that ‘diamonds are a girl’s best friend’ but it’s quickly becoming the pink kind that are the friendliest of them all.

The Argyle Diamond mine in Western Australia is renowned for producing the best pink diamonds in the world. Yes, you can find pink diamonds in other parts of the world, but nowhere can you find the exquisite clarity and luminosity of the pink diamonds found in the Argyle. However, there is a finite supply of these beautiful stones and it has been estimated that there is a maximum of 7 years left at this mine before it closes.

What does this mean?

Well, as with anything in scarce supply, the price of pink diamonds is, and will continue to steadily rise. To put things in perspective, the highest quality pure, 1 carat white diamond will cost around $35,000. The same high quality pink diamond is priced at $1,300,000!

The value of pink diamonds has been increasing by around 35% year on year but experts believe that values will skyrocket by around 500% once the mine closes.

With coloured diamonds and other stones increasing in popularity for engagement rings, a pink diamond could see you not only on trend, but also with a very sound investment piece.

What makes pink diamonds so special?

The truth is that scientists still do not completely understand how the natural pink colour is formed. All diamonds are comprised of carbon atoms. The way the atoms are bonded together in what is know as a crystalline lattice means that they can’t absorb light which is what gives them the pure colourless look we are all familiar with.

What scientists do know is that coloured diamonds have ‘defect centres’. This is where the lattice is missing some of the initial carbon atoms, or, another element has entered the mix.

Yellow diamonds are created because of the presence of nitrogen atoms, blue diamonds from boron.

However, what additional element has entered to create the pink hue remains a mystery.
