What are the Origins of Natural Pink Diamonds?

origins of pink diamond

Like any other diamonds, natural pink diamonds’ journey begins deep within the Earth’s core. They are subjected to extreme heat and intense pressure for millions or even billions of years. Under these conditions, carbon atoms crystallise and form diamonds. Natural pink diamonds cool and harden as they travel towards the Earth’s surface.

Natural pink diamonds are found only in few places across the globe. The biggest source of the highest-quality natural pink diamonds in the world is the Argyle Mine in Australia. It is located in the East Kimberley region in Western Australia, where 90% of all pink diamonds came from. Other natural pink diamond sources are South Africa, Russia, Brazil, India, Tanzania, and Canada.

How Rare and Valuable are Diamonds

Natural pink diamonds are extremely rare. They make up only 1% of the total diamonds mined; and of that 1%, only a 1 in ten is sellable. The natural pink diamond supply is currently decreasing as the Argyle Mine is set to close later this year. With this closing and the continuous demand for the natural pink diamonds, the international diamond market will have to deal with a supply shortage.

What gives them their characteristic pink hue? Even scientists are not quite sure, but there is a theory. On its journey to the Earth’s surface, scientists suggest that the diamond’s molecular structure gets altered. The deformation of their crystal lattice affects the electron transfer, which influences the way the gems absorb and reflect light. This results in the stone emitting the pink hue.

Natural pink diamonds are also unique. It is difficult to come by two pink diamonds that have the same cut and same style. That is why pink diamonds make for a truly one-of-a-kind jewellery piece.

Natural pink diamonds are highly valuable. Buyers pay up to 20 times more for these rosy gemstones compared to their white or colourless counterparts. The Australian pink diamonds, which are pure, high-grade, natural pink diamonds, cost anywhere from $100,000 to $1 million per carat! Thus, these natural pink diamonds are excellent investment pieces.

What are the Notable Pink Diamonds?

Said to be the most coveted among the coloured diamonds, many have paid huge sums of money to possess a beautiful rarity. But some pieces are more prominent than the others because of their ownership. Here are some notable examples:

How Pink Diamonds are Priced: The Colour Intensity Factor

You likely already know about the 4C’s of the diamond grading system — carat, colour, cut, and clarity. These 4C’s affect the diamonds price points, among the many other attributes. But in the case of coloured diamonds, more emphasis is put on the colour.

Natural pink diamonds come in a spectrum consisting of eight colour grades, from Faint to Fancy Deep. The more intense the colour is, the pricier it is. Aside from this, the secondary hue also affects the price of pink diamonds. Secondary hues range from brownish to reddish to purplish. The rarer the secondary hue, the more it adds to the price. Brownish undertone is the most common, while purple is rare. Therefore, pink diamonds with a brownish hue are more affordable than pink diamonds with a purplish hue.

When buying pink diamonds, always make sure that they are GIA certified. That will ensure that you know exactly what you are getting and paying for.
