PINK Diamonds

Pink Diamonds from Argyle

Pink diamonds have become one of the most sought after  diamond colours around the World. None more so than from our very own Australian Argyle mine within the Kimberly region of Western Australia. Whilst the exact scientific reason for the pink hues are still a little puzzling their colour and allure is for all to admire. 

Almost all other coloured diamonds exhibit a trace element, (eg:boron, nitrogen, hydrogen) which is said to help determine some colours. Pink diamonds are said to obtain their colours from the earths extreme forces when they were produced over a billion years ago.

Me Jewellery on the Central Coast have access to some of the rarest and finest from the Argyle range of Diamonds. Get in touch to see what we can find you.  The Argyle Mine has closed permanently.

Grading & Value

As previously stated Pink Diamonds from the Argyle Mine are graded utilsing the 4C’s diamond grading scale. Except the white diamond colour scale.  The image here depicts the colour grading scale for Argyle Pink Diamonds. There are three distinct attributes to determine the colour grading of a Pink Diamond.

There are also two variances that are worth mentioning to Investors. Argyle have used two differing  classifications of their diamonds Clarity.  The Certification of Authenticity from the Argyle Mine can show Clarities as ‘SIAV’  or P1,P2, P3.

‘SIAV’ appears to use this clarity grading as a generalised term instead of grading them SI1 or SI2.  The P1’P2’P3 gradings are an older term ‘pique’ for diamonds that are classed as ‘Included’.  The current diamond industry tends to use I1,I2 & I3. Diamonds with an I3 or P3 are heavily included. 

Let’s not get picky here though, we are talking ‘Rare’ Diamonds. However if you are talking ‘Tender Diamonds from the Argyle Mine’ then the clarity is worth noting that of the Tender Diamonds sold between 1990 to 2014 only 1.8% had a VVS Clarity, 13% were VS Clarity with the most being certified as SI at 85%.5 

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 intensity in the pink 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 diamonds. the range of tones extend from light to dark


Colour can be a personnel taste however Pink Diamonds are more valuable if their colour range is intense with Colours simply stated, RED – Purplish RED- PINKISH RED then flowing into categories in order of ‘Rareness’

  • 1PP -9PP “Purplish Pink”
  • 1P – 9P “Pink”
  • 1PR – 9PR “Pink Rose”
  • BL3 – BL1 “Blue Violet”
  • PC3 – PC1 “Pink Champagne”

Certificate of Authenticity

Genuine Pink Diamonds from the Argyle Mine come with a numbered Certificate of Authenticity for every diamond weighing over 0.08cts along with their identification number and Argyle Logo laser inscribed around their girdle.  For diamonds smaller than 0.08cts their Lot no’s will be supplied and can be traced back to the Argyle mine.

This detailed certification process gives us and you the customer peace of mind that you are in fact getting the real Australian Argyle Quality Diamond. 

The Argyle ‘Certificate of Authenticity’ cannot be duplicated or replaced, Rio Tinto stopped reissuing them in 2016.  The main reason was as a fraud deterrent.  Many Argyle diamonds are currently sold without their original certificate due to it being lost, damaged.  These Diamonds are often then re-certified by the GIA who do ‘note’ that the diamond has a previous laser inscription.  Written similar to A123456.

Of note is that the GIA grade Fancy Colour diamonds in their own terminology, not Argyles own grading scale.

In our opinion an Argyle Diamond without it’s ‘Original Certificate’ would be worth slightly less then one that came with it.

2019 – 2021

Whilst no one will deny that Covid-19 certainly put a dampener on almost every industry including the Diamonds, however the luxury item market stayed relatively steady and soon regained momentum since most people with vast wealth were only marginally affected by way of their ability to travel. Money was used in the purchasing luxury items.

Argyle stones over the past 10-15 years have increased their value up to 200 % and some considerably more with the rarest and largest stones.

I would say it requires around 3 years until you will earn back the original investment while exchanging. But this statement is mine alone, a Pink Diamond from Argyle over 0.50ct will have a much higher initial purchase price to begin with and may take even more time. Once more, you shouldn’t expect a quick sale and making a killing in the following a couple of months. We are finding buyers are diversifying their privately funded Superannuation with there rare Gems. Like with most investments, it’s the long term goals we look for, and I can’t see that changing, since the Mine is now closed.

As an investment strategy we are mainly focused on the Colour, Carat Weight and Clarity, the overall Cut doesn’t really come into play here unless you intend to use this Diamond in an article of Jewellery. The goal here is buy well and at the right price, don’t fixate on a round brilliant cut when all you are going to do is have it safely stored away for years. It’s an asset, be it beautiful and mesmerising to look at it is just an investment.

When buying an Argyle diamond, you will own a rare, disappearing heritage of Australia, which can not be reproduced or manufactured again.
When purchasing a Pink Diamond from the Argyle mine, you will own part of Australia’s history in it’s rarest and most beautiful form. Your Diamond cannot be remade or renewed from the Earth from where it was created.

Pricing seen at trade auctions over the past 2-3 years has risen exponentially and of course this price is then relayed into the consumer sector.

Colour grades in the 1-2P/1-2PR/1-2PP have also become increasingly rarer to find. Even smaller stones around 0.10 – 0.17 to 0.18 – 0.22 in good colours are becoming rarer.
