The quick answer
Natural pink diamonds are among the rarest coloured diamonds on earth, and Australia was their main source. The Argyle mine in Western Australia's Kimberley region closed in 2020 after 37 years, and it had been widely reported as the origin of around 90 per cent of the world's pink diamonds.
That makes pink diamonds a particularly Australian stone to buy, and it means the grading language is different from anything you have learned about white diamonds. Here is how it works.
What makes a pink diamond pink
Almost every coloured diamond gets its colour from a chemical impurity. Blue diamonds contain boron. Yellow diamonds contain nitrogen.
Pink diamonds contain neither. Their colour comes from something structural instead: distortion in the crystal lattice, formed under enormous pressure, which changes how the stone absorbs and transmits light. The pink is a property of the crystal's geometry rather than of anything added to it.
This matters for two reasons. It is why pink diamonds cannot be reliably predicted or sought out geologically the way other colours can, and it is why they occur in such small quantities.
The Argyle story, and why it matters to Australian buyers
The Argyle mine operated in the East Kimberley in Western Australia from 1983 until its closure in November 2020. Across 37 years it produced hundreds of millions of carats of rough diamonds, the overwhelming majority of them brown and industrial grade.
The pink production was a tiny fraction of that output, and it was enough to make Argyle the reference point for the entire category. Reporting at the time of closure put Argyle's share of global pink diamond production at around 90 per cent.
Two practical consequences for a buyer today:
Supply is finite and known. The stones that exist are the stones that exist. Nothing further is being mined at Argyle.
Provenance language is common in the market. You will see Argyle certification and Argyle lot numbers referenced. These apply to specific tender and certified stones, and a natural pink diamond without Argyle documentation is not a lesser stone. It is simply a stone without that particular paperwork.
We would add one note of caution. Scarcity is a fact. Future price movement is a forecast, and no jeweller can responsibly promise one. Buy a pink diamond because you want to wear it.
How pink diamond grading works
This is where buyers used to white diamonds have to set aside most of what they know.
For a white diamond, colour is graded on the D to Z scale and less colour is better. For a coloured diamond the entire logic inverts: colour is the value, and it is assessed across three separate dimensions.
### Hue
The basic colour family. Pure pink is the reference point. Many stones sit slightly off it, described as purplish pink, orangey pink, or brownish pink. The modifier tells you what else is present.
Purplish pink is generally well regarded and can be very beautiful. Brownish modifiers tend to reduce value most.
### Tone
How light or dark the stone is, from very light through to dark. Mid tones usually show colour most attractively, since a very light stone can read as near colourless in some lighting and a very dark one loses brilliance.
### Saturation
The intensity of the colour, and the dimension that moves price most. The recognised sequence runs roughly:
- Faint and Very Light: colour is present but subtle
- Light: clearly pink, gentle
- Fancy Light: the point at which most people would describe it as obviously pink
- Fancy: strong, even colour
- Fancy Intense: vivid and unmistakable
- Fancy Vivid: the top of the scale, and genuinely rare
- Fancy Deep and Fancy Dark: darker expressions of strong colour
The jump from Fancy to Fancy Intense to Fancy Vivid is where price accelerates sharply.
### What matters less than you expect
Clarity. In a white diamond an inclusion is a flaw. In a coloured diamond it is often invisible against the body colour, and a slightly included pink diamond with excellent colour is worth considerably more than a flawless one with weak colour. Colour first, always.
Cut. Coloured diamonds are cut to maximise colour rather than brilliance, which is why you see cushion, radiant and oval shapes far more often than round brilliants. A cut that looks unusual by white diamond standards is usually a deliberate choice to concentrate the colour.
Carat. Pink diamonds are typically small. A pink diamond over one carat is a significant stone, and most pieces on the market use smaller stones, often as accents or in clusters.
Reading a pink diamond listing
Fine jewellery listings compress a lot into a short string, and once you can read it the comparison gets much easier.
A typical description separates the coloured stone from the white diamonds around it. In our listings, for example, a piece described as pink diamond D0.126 with d0.421ct in 18K gold is telling you the pink diamond weight and the accompanying white diamond weight separately.
What to look for:
- The pink weight on its own. This is the stone you are buying. Total carat weight across all stones can make a piece sound larger than the pink content is.
- Whether the colour is natural. Treated and lab-created pink diamonds exist and are legitimate products at very different prices. Natural should be stated explicitly.
- The metal. 18K white gold and rose gold are the common settings, and rose gold warms the pink noticeably.
- Certification, where the stone is large enough to warrant it.
Every piece we list is authenticated before it goes on the site.
Pink diamond settings that work
The design problem with a pink diamond is that the stones are usually small and the colour is the point. Settings exist to solve that.
### Halo
A ring of white diamonds around the pink centre. It increases apparent size and, because the white stones give the eye a colourless reference, it makes the pink read as more saturated. The most common approach for a pink centre stone and, for most buyers, the most effective.
### Rose gold
Setting a pink diamond in rose gold rather than white extends the colour into the metal. The stone reads warmer and larger. Purists prefer white metal for a truer colour reading; most people find rose gold more flattering.
### Cluster and pavé
Where individual stones are small, grouping them creates presence that no single stone of that size could. This is the approach behind many pink diamond bracelets and pendants, and it is usually the most accessible entry into natural pink.
### Two-tone and mixed colour
Pink alongside yellow or white diamonds. Our current pink diamond ring listing pairs natural pink with natural yellow diamond, which sets each colour off against the other rather than against white.
### Bezel
A metal rim around the stone. Protective, contemporary, and it can slightly deepen the perceived colour by removing surrounding light.
Beyond rings
Rings dominate the search interest, and they are not always the best way to buy pink.
### Necklaces and pendants
A pendant sits where the light is good and the stone is seen against skin rather than against other jewellery. For a small pink diamond, a pendant often shows the colour better than a ring does. Our pink diamond necklaces and pendants include feather and lock-shaped designs built around natural pink centres.
### Bracelets
A bracelet distributes stones along a line, which suits the small sizes pink diamonds usually come in and creates movement as the light changes. See the pink diamond bracelet listing.
### Earrings
Pairs are the difficulty. Matching two pink diamonds for hue, tone and saturation is considerably harder than sourcing one, which is why pink diamond earrings appear less often and command a premium when they do.
What pink diamond jewellery costs in Australia
Pricing depends far more on the colour grade of the pink than on total carat weight, which makes headline comparisons misleading. As a reference point, natural pink diamond pieces in our current collection sit between roughly A$2,000 and A$4,500, covering pendants, a bracelet and a two-colour ring, all in 18K gold with accompanying white diamonds.
That range reflects pieces using smaller pink stones in well-made settings. Certified stones in higher saturation grades, and anything approaching or exceeding a carat of pink, move into a different bracket entirely.
Because availability changes, current pricing is always on the listings themselves. Browse the natural pink diamond collection for what is available now.
Pink, yellow or white: choosing between them
Buyers considering a pink diamond are often weighing it against the alternatives, and the three behave differently.
| Pink diamond | Yellow diamond | White diamond | |
|---|---|---|---|
| Source of colour | Crystal lattice distortion | Nitrogen | None |
| Relative rarity | Extremely rare | Rare, though far more available than pink | Widely available |
| Typical size available | Small, often accent scale | Small through to large centre stones | Any size |
| Graded on | Hue, tone, saturation | Hue, tone, saturation | Absence of colour |
| Best setting approach | Halo or rose gold to amplify | White metal for contrast | Anything |
If you want a coloured diamond at centre-stone size, yellow gives you far more options. If rarity and an Australian connection matter to you, pink is the stone. Our yellow diamond collection and white diamond collection sit alongside the pink pieces if you are comparing.
Caring for pink diamond jewellery
Diamond is the hardest natural material, so the stone itself is robust. The setting is what needs attention.
- Clean with warm water, a drop of mild detergent and a soft brush, then dry thoroughly.
- Avoid ultrasonic cleaners on pieces with many small pavé stones, where vibration can loosen settings over time.
- Remove jewellery before swimming, gardening or applying cosmetics and perfume.
- Have claw settings checked periodically, particularly on rings worn daily.
- Store pieces separately. Diamond scratches everything, including other diamonds.
Frequently asked questions
Why are pink diamonds so expensive?
Because natural pink colour is caused by rare structural distortion in the crystal rather than by a common impurity, and because the main global source, the Argyle mine in Western Australia, closed in 2020 after 37 years of operation. Supply is limited and does not replenish.
Are all pink diamonds from Argyle?
No. Argyle was widely reported as the source of around 90 per cent of the world's pink diamonds, and other deposits do produce them. A natural pink diamond without Argyle documentation is not a lesser stone.
How can I tell if a pink diamond is natural?
Treated and lab-created pink diamonds are legitimate products sold at very different prices, and distinguishing them is laboratory work rather than something visible to the eye. Buy from a seller who authenticates what they list and states clearly whether a stone is natural.
Is clarity important in a pink diamond?
Much less than in a white diamond. Inclusions are often invisible against the body colour, and colour quality drives value. A slightly included stone with strong colour is worth more than a cleaner stone with weak colour.
What size pink diamond should I look for?
Most pink diamonds on the market are small, and anything over one carat is significant. Rather than chasing size, look at saturation grade, and consider settings such as halos and clusters that give a small stone presence.
Does rose gold change how a pink diamond looks?
Yes, noticeably. Rose gold extends the colour beyond the stone and makes the pink read warmer and larger. White gold gives a truer reading of the stone's own colour. Neither is wrong, and it is worth seeing both.
Are pink diamonds a good investment?
Scarcity is a matter of record; future value is not. We would encourage buying a piece you want to wear rather than treating jewellery as a financial instrument.
