The story of the Argyle pink diamond is almost as captivating as the rare gem itself. Across the breadth of 1.6 billion years, on a journey from the Earth’s centre, the most intriguing diamond in history emerges, with an exquisite beauty that is both regal and mesmerizing.

Argyle Pink Diamond Colour Grading
The three attributes, which determine the colour grade of a Pink Diamond, are:
Hue
The dominant colour of the diamond. Sometimes there are modifying colour or tints that affect hue. For example, a diamond with a pink hue may have a purplish tint.
Saturation
The strength in the pink of the hue. Hue saturation in pink diamonds can range from light pink to intense, and at the strongest, saturation vivid.
Tone
The amount of lightness or darkness in the diamond. The range of tone extends from light to dark.
Round Brilliant
Investment Pink Diamonds
Just like in the white diamond world will always sell for a premium over a traditional or modified fancy shape. This is because of their additional cutting wastage. Logically most people think that a round cut is the best option to invest in, this concept is an interesting one as ADI has found over the past 11 years that round pink diamonds up to 0.39ct will always be a fantastic investment but round pink diamonds larger than 0.50ct will generally return a lower profit margin due to the initial higher purchase price. There are also fewer buyers at the top end of the pink diamond price market.
Modified Fancy Shape
Investment Pink Diamonds
May at first look interesting and will generally sell at a discount over a round brilliant or traditional fancy shape. However, when it comes to profit building, regardless of how nice the colour appears should be avoided. This is because when it comes time to sell the pink diamond the potential buyers will be so few that you may have to sell at a heavy discount. The majority of pink diamond investors will not step too far away from what is considered an established investment.
Traditional Fancy Shape
Investment Pink Diamonds
Are predominantly abundant and offer a wider select of colour tones and saturations. They normally sell at a reduced price over an equivalent round brilliant and are very popular with mainstream investors. These are reasons you are more likely to return a greater profit over a round brilliant or modified fancy shape. Sticking to a traditional fancy shape or round shape under 0.39ct will strengthen your buyer audience.
Rare and Luxurious Investments
Pink diamonds are recognized as extremely luxurious items. The increase in rarity together with their popularity has significantly driven pink diamond prices up. Consequently, they are often utilized as additions to investment portfolios as excellent alternative investments.
All diamonds are assessed by the same four main attributes of diamond quality; Colour, Cut, Clarity, and Carat Weight. However, unlike white diamonds where the 4Cs are of the same importance, the colour of a Fancy Colour Diamond is the most significant characteristic of all.
Secondary Pink Diamond Hues
Similar to other colours, a pure coloured pink diamond without any secondary hue is more valuable. However, as a result of its magnificent appearance, a purplish pink diamond is also considered most preferred.

What Causes Pink Diamond Colour
The unique colours in the stones are caused by different trace minerals within the compound elements of the diamonds. Depending on the origin of the stones, meaning where it is from, certain minerals are more present – therefore increasing the presence of specific colours in certain areas.
Unlike Yellow Diamonds where the colour is caused from large amounts of Nitrogen, Blue Diamonds where the colour is caused by Boron, Purple or Violet Diamonds where the colours are caused by increased Hydrogen, or Green Diamonds where the colour is caused by exposure to atomic radiation or radioactivity – the cause of the Pink Diamond colour actually still remains questionable. Scientific evidence has shown that Pink Diamonds contain high pressure graining which results in a compressed internal structure and that is thought to be the origin of the colour. Within the industry, this is referred to as ‘Plastic Deformation,’ which occurs during the crystal growth.
As a result of the increased pressure, it is extremely difficult to find a Pink coloured diamond with a high clarity grade. In fact, most Natural Pink Diamonds often contain pink internal graining lines or surface graining lines within the atomic structure of the stones. Although this is a natural defect found in most, but not all, pink diamonds it still can slightly affect the clarity of the diamond – bringing for example from an IF to a VVS1/2.
Pink Diamond Jewellery
Even with the relatively high prices of pink diamonds, as a result of their exquisite colours, they are often used in various designs of colour diamond jewelry. See for example these amazing photos of Pink Diamond Engagement Rings, Pink Diamond Earrings, and Pink Diamond Pendants.
Natural Pink Diamonds have always been seen among the very rich and famous. Even today, many of the Hollywood stars adorn the most glamorous pieces of pink diamond jewelry. Just some of the more famous examples are Ben Affleck who presented an unbelievably gorgeous 6-carat pink diamond ring to Jennifer Lopez. Mariah Carey’s Diamond Engagement Ring contains a 10.02-carat Pink emerald-cut diamond, and Penelope Ann Miller was happy to show off her 3.00ct Pink Radiant Diamond Ring at the 2012 Academy Awards.
