As some of the world’s rarest diamonds, pink diamonds are objects of desire for jewellery aficionados and investors alike.

They have a romantic beauty that’s impossible to replicate. And, since it’s so difficult to obtain a pink diamond - especially one from the Argyle mine - their value is consistently impressive.

Pink diamond owners and potential buyers should never neglect an Argyle pink diamond valuation, which goes much further than just putting a price tag on your jewellery.

 Discover why with this guide.

Diamond valuers judge diamonds by a set of factors: Colour, clarity, cut, carat weight and origin.

Colour: The intensity of the pink shade has a major impact on the value of a diamond. Pink diamonds are graded on a scale from “Fancy Light Pink” to “Fancy Vivid Pink”, where a more intense colour corresponds with a higher value.

Clarity: Clarity measures the presence of blemishes (external flaws) and inclusions (internal flaws) in a diamond. A stone with fewer blemishes and inclusions is more valuable

Cut: “Cut” describes the diamond’s symmetry, proportions and finish. Well-cut diamonds have more brilliance and sparkle, which increases their value.  

Carat weight: Generally, larger pink diamonds are more valuable. However, carat weight isn’t the biggest driver of price. So, a smaller diamond with fewer inclusions is usually worth more than a larger stone with many inclusions.

Origin: The rarity and quality of a diamond make it more valuable. Pink diamonds from the Argyle mine of Western Australia are highly coveted. Since the closure of the mine in 2020, they’ve become even rarer and in higher demand, so hold a consistently high value.

While we already know about the factors that influence the price of Argyle pink diamonds, it makes sense to have a general overview of the market.

That way, if you’re thinking of investing in pink diamonds, or you already own pink diamond jewellery, you’ll have more clarity on price point and resale value.

In general, pink diamonds are regarded as a safe investment. Their value has increased steadily over the past couple of years, thanks to their scarcity, high market demand and limited availability.

The closure of the Argyle mine, plus the influence from Tiffany (who purchased 35 pink diamonds from the Argyle mine and further raised their profile), have driven up demand even further. Thus, we’ve seen the value of pink diamonds skyrocket since 2020.

Let’s put a number on that. According to the Fancy Colour Research Foundation, there has been an overall appreciation of the value of fancy-coloured diamonds. Between 2005 and 2023, the value rose by 211%. In that time, pink diamonds have had the most significant gains, growing in value by 396%.

The Australian Diamond Portfolio Pink Diamond Index (ADPPDI) reports a 17.7% average growth per year, with pink diamonds outperforming gold, silver, the ASX, property and “just about any other hard asset”.

They recently reported that, although the latest market conditions have seen demand level off, prices continue to stay steady. They expect a range of catalysts, including inflation and an economic slowdown, to push demand and prices higher.

It’s important to find a reputable jewellery appraiser who can provide a valid appraisal.

Take any supporting documentation you have, such as sales receipts, grading reports and previous valuations.

During the appraisal, the jeweller will examine your pink diamond jewellery, paying particular attention to the colour, carat weight, clarity and cut of the diamond. They’ll also inspect the metal’s quality, looking for signs of wear or damage.

They’ll value your jewellery based on current market conditions, and you’ll receive a full report with photos of your piece.
