Pink Diamond Education
Before purchasing a pink diamond for any purpose it is very important to educate yourself on the unique quality aspects to ensure you make the correct selection. Pink diamonds are very expensive and the grading priority is very different to selecting a standard diamond.
Why are Diamonds Pink?
Pink diamonds are beyond rare and one of nature’s true beauties. The pink colour within a diamond is not created through anything being added to the diamond but through a warped disruption of the diamond’s crystal lattice that alters the light entering the diamond causing only the pink spectrum of light to emerge.


High Demand and Price
With such rarity and beauty comes high demand and inevitably high prices. Pink diamonds are a true luxury for those who desire to own one of these magnificent gems. Colour is by far the determining factor to selecting a pink diamond and how it relates to the purpose of the purchase.

Pink Diamond Colour Grading
To greatly improve the pricing structure of pink diamonds where almost every diamond has its own unique colour traits, Argyle, developed its own colour grading system to better describe their vast collection of pink diamonds.
To assess the value of pink diamonds their colour grading system has 35 different registered colour grades to cover the wide variety of colour tones produced by the mine.
Graded from 1-9 (darkest – lightest) in tones of pure pink (P), purple-pink, (PP) rose pink (PR), champagne pink (PC) and the very rarest red.
How to select a pink Diamond
Selecting a pink diamond is about understanding the purpose of the purchase and how the grading relates to the quality needs of the purchase.
Demand will always outweigh Availability
With only one pink diamond for every one million carats unearthed, the demand for these ultimately rare diamonds will always mean the availability of nature’s true beauties will be scarce.
The price of an Argyle mine origin diamond is as much as 300 times the cost of a white diamond and with such limited availability once the budget has been set then the selection will come down to generally only a handful of possible diamond options. The contributing factors to selecting an Australian pink diamond are: budget, size, clarity, shape, colour and availability.
When most people think of diamonds they think of the round shape. However, fancy coloured diamonds are better suited to fancy shapes like radiant and cushion cuts to retain the greatest carat weight and create depth of colour. Round diamonds are the most popular but also the most expensive, making shape a deciding factor when looking for size and colour for your budget.
What colour pink diamond should I choose?
The deeper or more intense the colour of a pink diamond the more expensive it will be and the more difficult it will be to source.
Choosing your colour is usually going to be a balance between what you find attractive and what is going to work best for the intended purpose.
The colours that we find are the most attractive and popular with our clients due to their saturation and reasonable value are graded from 3-6 P, PP and PR. The smaller diamonds in this grade do need to be clustered to help enhance their colour and larger stones will be quite visibly pink and are suitable for jewellery and investment.
Pink diamonds graded from 7-9P in colour are faint to very light pink in colour and provide a very subtle pink appearance and often require a little enhancement to be noticed in jewellery are lower on investment attractiveness.
The deepest and vividly noticeable pink diamonds even in the smallest of stones are graded 1-3P/PP/PR in colour, these are the true collector pieces for high-end investment and stunning luxury jewellery.
With each single jump in colour grade the price can almost double for a similar size stone, which means making the right colour choice an imperative part of your selection.

Diamond clarity selection
Clarity is the Achilles Heal of the Argyle diamond mine, with such beauty comes one flaw. The clarity of these magnificent diamonds is more often below the standard you would expect for such an expensive purchase but is fortunately masked within the colour of the diamond. Despite their price, it is quite common to have near or slightly visible grade inclusions in an Australian pink diamond.
Clarity plays a very important factor in the price and with the focus on the colour, clarity is still often the preferred sacrifice. An eyeclean diamond will always remain important to most buyers and a SI1-2 grade is generally sufficient.
A visibly included or Pique P1 grade diamond is fine for appearance and jewellery but is a defining factor with investors. The rarer and more desirable the other factors the more acceptance there may be for a P1 clarity grade diamond but more common diamonds will have less need to select a lower grade clarity.
P2-3 clarity can be quite included but often ideal for jewellery.
Finding a higher clarity pink diamond in the VS-VVS range is very difficult to acquire and does increase the absolute rarity of the diamond and will certainly increase the worth of the stone. However, it will not significantly increase the demand for the diamond, as many investors see less value in purchasing a pink diamond of high clarity over the ability to increase the size or colour.

With such an expensive purchase making the right decision can only be done with the assistance of an experienced diamond merchant who can walk you through the selection process and assist with finding the diamond that will be the most appropriate for your requirements.
