Pink diamonds are no longer just the favourite of pop stars and A-listers. Argyle pink diamonds have become increasingly popular with collectors due to their rarity, beauty, and history. Here’s a look at six amazing facts about pink diamonds which will make you think about investing in them.
Pink diamonds are extremely rare
It’s not just the rarity of pink diamonds that makes them so special, but their stunning colour. Pink diamonds are the rarest of all coloured diamonds. Only 1-2% of all diamonds mined worldwide are pink. To put it another way: if you were to gather up every single person on Earth, it would be more likely that one of those people is an alien than it would be for them to find a pink diamond within their first search.
They’re costly and difficult to find because they are hard to cut and sell.
Argyle pink diamonds can be found in various shapes and sizes
A pink diamond can be found in its natural form in the round, pear, oval, marquise, heart and cushion shapes. Larger Argyle pink diamonds are also cut into radiant or emerald shapes. Some of the largest faceted pink diamonds have weighed 10 carats!
Naturally coloured pinks are extremely rare—the vast majority of natural coloured diamonds are yellow or brownish. This is because the vast majority of naturally mined diamonds come from hundreds or even thousands of years old mines. In this period, some impurities can build up within these underground layers and leach out onto the surface, where they can alter the colouration of any new-found stones formed thereon by giving them an orange tint.
No two pink diamonds are the same
No two pink diamonds are the same. Each is unique, with varying shades of pink, sizes and shapes. They can also differ in clarity.
Size: Pink diamonds vary greatly, ranging from 1 carat to 50 carats. For example, a 3-carat round brilliant cut pink diamond can be worth as much as $250,000, while a 15-carat cushion shape diamond could cost upwards of $400 million (if it’s flawless).
Shape: Pink diamonds come in different shapes like rounds and ovals, but they are most commonly found as hearts or cushions because they’re more popular than other cuts like an emerald cut or brilliant square cuts, which have fewer facets that reflect light
Pink diamonds get their colour from incredible pressure
The carbon atoms in the diamond’s crystal structure rearrange themselves to form a pink colour, and this can only happen when the diamond is subjected to tremendous force.
For example, when magma (molten rock) rises from deep within the Earth’s crust, it can become trapped below layers of minerals and sedimentary rock. When that magma eventually explodes through these layers, it forms an underground chamber called a kimberlite pipe, named after their discoverer, Sir Philip Francis Kimberley. These pipes often contain diamonds; some can be hundreds of meters wide! The most valuable pink diamonds are found at the bottom of these pipes because they were buried under more than 1km of rocks before being brought to the surface by volcanic eruptions.
Pink diamonds are as old as 1.2 billion years
These are the oldest diamonds known to man and can be found in kimberlite pipes formed when an asteroid impact occurred on Earth. The pink diamond was named after its colour, which is caused by trace amounts of nitrogen within the diamond matrix.
Natural pink and red diamonds are more expensive
Pink and red diamonds are rarer than other colours, so they’re more expensive. This is due to their colour resulting from natural processes that occur during the formation of diamonds. Because these processes are so complex and difficult to replicate artificially, pink and red diamonds are hard to come by—and you’ll probably pay more for them when you find one.
So there you have it, eight amazing facts about the pink diamond. You’ve learned something new and enjoyed reading about these beautiful stones.
