WHERE DO ARGYLE DIAMONDS GET THEIR COLOUR FROM?

Argyle diamonds originate from Argyle mine located in the western part of Australia. The Argyle mine has been operating since 1983 in the remote East Kimberley region. The mine is considered as one of the largest mines producing diamonds throughout the world. Around 8 million carats of rough diamonds have been produced by the mines that make it one of the world’s largest producer and supplier of naturally occurring coloured diamonds.

 

ARGYLE DIAMONDS CAN BE FOUND IN DIFFERENT COLOURS SUCH AS RED, PINK, BLUE VIOLET AND CHAMPAGNE.

 

Among all of these naturally coloured diamonds, pink, red, blue and violet diamonds from the Argyle mine are very rare. The diamond from Argyle mine is considered rare due to their unique composition. The Argyle pipe that is also known as the volcanic pipe and is made up of olivine lamproite is responsible for their distinctive composition.

The minerals found under the surface of the earth for instance micas, clays, zeolite and kaolinite due to eruption interact with the argyle diamonds during the process of formation. It has further been observed that the Argyle diamonds contain nitrogen impurities in smaller amounts as well, that plays an important part in their colour formation. Majority of the colour in argyle diamonds is observed to be as a result of structural defects in the crystal lattice of the diamond.

WHERE ARE ARGYLE DIAMONDS FOUND?

Deep beneath the earth, naturally coloured diamonds were formed around billions of years ago. Another most interesting fact is that it takes some unfamiliar circumstances for the diamonds to be produced with colours. Some of the remarkable hues have been observed as a result of impurities trapped in the crystal lattice. Geologists have been exploring the world for seeking these highly rare and valuable stones.

IN 1979, A DIAMOND WAS FOUND IN THE KIMBERLEY REGION OF WESTERN AUSTRALIA.

 

The discovery of diamond resulted in the opening of argyle mine in the year 1983. The Argyle mine was opened with a belief that there would definitely be more diamonds there. After 1979 and till date, the geologists have found some of the most amazing and magnificent naturally coloured diamond from the Argyle mine. Today a vast majority of naturally coloured diamonds come from the Argyle mine. The coloured diamonds have also been discovered by the geologists in other parts of the world including Africa but Argyle mine is the only single mine that has shown a consistency in the supply of naturally coloured diamonds.

WHICH ARE THE FAMOUS ARGYLE DIAMONDS IN THE WORLD?

The Argyle mine, in comparison to the other diamond mines in the world, alone is responsible for the production of almost 90% of the high-quality pink diamonds in the world. An impressive array of the collection of pink diamonds from the Argyle mine has been observed. For this reason, the Argyle mine, besides the other natural coloured diamonds, is famous more for its pink coloured diamonds with rare characteristics.

As has been stated previously the Argyle mine supplies around 90% or in other words 4000 carats of pink diamonds. Low production of both, red and pink diamonds has been observed throughout the world. It, however, is an undeniable fact that the Argyle mine is the only reliable source of naturally occurring red and pink coloured diamonds in the entire world.

THE ARGYLE DIAMONDS

The argyle mine is famous for its pink, blue, red and violet diamonds the most. There are very few mines in the wide world that produce blue diamonds and the most important ones are known to have come from only three particular locations including argyle mine. Red diamonds from argyle mine are also among one of the rarest diamonds while the violet diamonds from argyle mine have also got fame for its historic significance.

 

The value of a coloured diamond also increases with its depth

 

All the existing naturally coloured diamonds are preferred as they occur naturally. A pure diamond without any additional features would definitely be more valuable. Modification in the colours, most commonly called overtones or secondary colours, has its own impact on the prices. The positive or negative influence on the prices, however, depends significantly on the colour tone. From the pink diamonds, a purplish pink diamond is mostly preferred due to its magnificent and eye-captivating appearance. The diamonds with more of brownish colour are generally preferred as they are more affordable than the others.

 

The colouring of the diamonds found from the Argyle mine, itself is so unique.

The fancy diamonds have been expected to become the most common investments in the near future. As the Argyle mine is particularly famous for its pink diamonds. Over the years, the prices of some high-quality diamonds including the large pink diamonds exclusively from Argyle mine have appreciated significantly as a result of their limited supply and increased demand from the collectors.

Let us consider an option of the pink legacy diamond that was sold at a record price of $ 50 million at an auction. In case of a coloured diamond, the intensity and saturation of a diamond are the two most important features to be considered. Most of the pink diamonds in the world often display a colour modifier such as brown, orange or grey. What makes the Pink Legacy different from the others is no trace of secondary colour present. Another interesting fact is that only one in 100,000 diamonds have such a colour that makes it qualify as the “Fancy Vivid”. A balanced tone and saturation together with the colour evenly distributed all throughout the diamond are some of the most amazing features of a naturally coloured diamond. Another interesting point here to note is that only a few diamonds in the wide world have such amazing features and those that have been discovered have their origin as the Argyle mine located in Western Australia.

We have seen some of the most phenomenal and unbelievably remarkable diamonds of different colours, shapes and sizes sold at the diamond auctions each year.
