It is too fair to say pink diamonds are a worthy and worthwhile investment and will be for many years to come. Pink diamonds originate from Australia. In fact, 90% of the world’s natural pink diamonds are produced in Australia. Pink diamonds are among the most desired coloured diamonds due to their rarity, femininity, beauty, and unique, romantic colours. pink diamonds are among the rarest coloured gemstones, alongside red, blue and violet.

What makes a pink diamond?

Not all pink diamonds, colours and hues are seen as equal. Just like many fancy-coloured diamonds, pink diamonds come in many different shades.

There are three pink diamond attributes that determine its colour grade, including its hue, saturation, and tone. A pink hue should be the diamond’s dominant colour, although some factors, such as its tint, may cause it to vary. The pink diamond saturation determines the strength of the pink colour of the pink diamond.

The saturation and shades range from faint, very light, light, fancy light, fancy intense, fancy deep and fancy vivid.

The pink diamond tone ranges from light to dark and establishes the lightness, darkness and value of the pink diamond. The more intense the pink diamond colour, the higher the cost. For example, a rich, pure pink-coloured natural diamond, graded as a Fancy Vivid Pink, will be exponentially costlier than a Fancy Pink or Fancy Light Pink Diamond.

What are Pink Diamonds Called?

Pink diamonds are named using a pattern developed by the GIA (Gemological Institute of America). The pink diamond’s carat is determined and stated, and then the stone’s hue (dominant colour) is tested to see if pink is the dominant colour. The pink diamond carat weight determines whether a pink diamond is called a ‘fancy vivid’, which means it has achieved the highest value, intensive natural fancy colour diamond grade.

Even with a hue of another colour, it is still named a pink diamond. A pink diamond can also sometimes display a purplish tint. Although, a pink diamond with a purple tint is valued the same as a pink-only hue.

You’ll never find the same pink diamond twice. Pink diamonds often come in a wide array of secondary colour hues, not just pink, including an orange hue.

Although pink diamonds are more valuable if another colour or overtone is not present. Some countries typically tend to produce pink diamonds with another colour present. For example, pink diamonds mined in South Africa and Brazil often present a brownish hue.

What is an Argyle certificate?

An Argyle certificate is a gem authentication and identification document issued from the Argyle Diamond website. An Argyle certificate must be provided on all argyle diamonds weighing over 0.08cts.

How are Pink Diamonds Formed?

Natural pink diamonds are formed over millions, sometimes billions, of years from a carbon element. They are heated at around 2,2000 degrees Fahrenheit over 100 miles within the Earth’s core. They remain within the Earth’s core over millions of years, cooling into solid form rocks.

Most pink diamonds are formed differently than others and are sourced from a volcanic lamproite pipe, differing from the usual kimberlite pipe.

Pink diamonds are created under unimaginable conditions, with carbon elements forming and growing within the stones into rough diamond rocks under immense heat and pressure, building and enduring under the earth over time.

What Causes the Pink Diamond Color?

Pink diamonds have a compressed internal structure. The origin of the pink colour is believed to be due to the immense pressure buildup, although this has never been proven. It is also thought that the compression of the grains is significant, as only pink light shines through and penetrates the diamond.

Pink diamonds are believed to be unusual because other fancy-coloured diamonds’ colour origins are due to impurities. For example, the canary diamond is caused by nitrogen buildup. However, a pink diamond’s colour is thought to be formed due to the diamond’s crystal lattice.

One theory behind pink diamonds’ colour is structural deformation called ‘plastic deformation’, which causes the structure of the diamond to deform or alter when it is forced to the Earth’s surface. Therefore the ‘plastic deformation’ would cause the pink diamond to absorb light differently, causing it to emit a pink hue.

Are Pink Diamonds Natural?

In fact, 80% of the diamonds mined at the Argyle mine are brown diamonds, and of every 1 million carats mined, only 1 carat of pink diamonds is graded suitable for resale. An average of 40 – 50 carats are sold annually at auction.
