Diamonds are one of the most revered gemstones – adored by romantics, collectors and investors all over the world.
But not many people know the incredible journey a natural diamond takes from inception to jewel. In fact, most natural diamonds are millions, if not billions, of years in the making.
How are diamonds formed?
Despite popular belief, diamonds are not made from coal.
For diamonds to form there must be very specific conditions, including an available carbon source and relatively narrow ranges of temperatures and pressures, all happening around 100 miles below the Earth’s crust.
Billions and billions of carbon atoms bond together at high pressure and scorching temperatures to form the crystalline structure that makes up a single diamond carat.
Once the diamonds have crystallised, they must be brought to the surface quickly and the only way for this to happen is through a volcanic eruption.
Analyses of diamond formations from various deposits worldwide have found their age to range from 3.5 billion years to 90 million years – to put it into context, that’s long before dinosaurs even existed.
Where are most diamonds formed?
Diamonds are found in over 30 countries worldwide; the leading producers of diamonds are Russia, Botswana and Canada.
However, diamonds come in all shapes, sizes and colours and it’s these factors that determine their demand and value.
Pink diamonds are some of the most rare and scarce in the world. The birthplace of almost all of the world’s pink diamonds (90%) is the Argyle mine in the Kimberly region of Western Australia, which closed its doors in 2021.
The closure of this mine caused a stir amongst pink diamond investors as there have been no recent discoveries of viable mining opportunities to replace it.
If a new mine was discovered in the near future, it would still take approximately 15 years to reach the stage of producing diamonds to sell to consumers and investors.
This makes pink diamonds, not only extremely rare but increases market demand and boosts their investment value.
Where can I buy a pink diamond from the Argyle Mine?
When considering the purchase of a pink diamond from the Argyle Mine, certification is one of the most important elements.
