Rare Pink Diamonds
Fewer than 0.01% of all natural diamonds. With the permanent closure of the Argyle mine — which produced over 90% of the world's pink diamonds — these gems have become one of nature's most finite treasures.
Fewer Than 0.01% of All Diamonds
Pink diamonds captivate with their extraordinary beauty and represent one of nature's rarest phenomena. Accounting for fewer than 0.01% of all natural diamonds — the world's entire annual yield of pinks would fill a single champagne flute — these gems have become increasingly precious and sought-after by collectors and investors worldwide, particularly following the permanent closure of the Argyle mine in Western Australia, which produced over 90% of the world's pink diamonds for nearly four decades.
Each pink diamond in the RARE.DIAMONDS collection has been meticulously evaluated and selected by fifth-generation diamantaire Brian Gavin for exceptional color, cut precision, and long-term value.
A Finite Resource
The Argyle mine in Western Australia's East Kimberley region was the world's only consistent source of pink and red diamonds from 1983 until its closure in November 2020. Its discovery roughly doubled world diamond production overnight, yet pinks were a vanishing fraction of its output. The closure marked the end of an era, creating an immediate and permanent supply constraint that has fundamentally altered the pink diamond market.
Key Facts:
- Fewer than 0.1% of the diamonds Argyle mined were pink
- Only a fraction of those achieved Fancy Intense or Fancy Vivid grades
- No comparable source has been discovered despite extensive global exploration
- Existing Argyle stones now carry significant provenance premiums, and that premium has widened since closure
- The mine's 37-year production history makes every Argyle stone a piece of geological history
The Argyle Tender Program
From the mid-1980s until 2020, the Argyle Pink Diamonds Tender selected the finest 50-60 stones each year — pinks, reds, and the occasional violet or blue — for exclusive sale to invited buyers worldwide. It became the most prestigious and anticipated diamond sale in the world. These stones represent the absolute pinnacle of pink diamond rarity and quality, with many achieving record prices and entering prestigious collections.
Tender diamonds are accompanied by unique certificates that document their selection for this elite program, adding historical significance and enhanced value beyond their intrinsic beauty.
Future Supply Uncertainty
Pink diamonds do surface elsewhere — Brazil, South Africa, Russia, Tanzania, and Canada have all produced them, and southern Africa has yielded some remarkable recent finds: Lucara's 62.7-carat Fancy Pink rough from Botswana in 2021, the 170-carat Lulo Rose from Angola in 2022, and the 108.39-carat Kao Legend from Lesotho. But none of these sources approaches the consistent quality, distinctive color character, or volume of Argyle production. Industry experts estimate that current alternative sources produce fewer than 50 investment-grade pink diamonds (1+ carat, Fancy or better) annually worldwide — compared to several hundred from Argyle at its peak.
This permanent supply-demand imbalance positions pink diamonds as one of the most compelling rare asset classes — grounded in fundamental scarcity rather than market speculation, though as with any tangible asset future performance cannot be guaranteed.
The Mystery of Color
Unlike other colored diamonds where the color cause is clearly understood (boron for blue, nitrogen for yellow), the origin of pink in diamonds remains one of gemology's fascinating mysteries. Scientists believe the pink color results from plastic deformation in the diamond's crystal lattice — a structural anomaly rather than chemical impurity.
This process occurs when the diamond experiences enormous stress deep within the Earth's mantle, causing microscopic distortions in the crystal structure. These distortions selectively absorb certain wavelengths of light, creating the captivating pink appearance. The greater the deformation, the deeper the pink — and at the extreme, the stone reads as red. The specific conditions required for this phenomenon make pink diamonds extraordinarily rare. Learn more in our Science of Diamond Color guide.
Why Pink Diamonds Are Small
The same forces that create the color also limit the crystal. The pressure that distorts the lattice enough to produce pink also fractures crystals, introduces internal strain, and prevents large, clean stones from forming; many potential pinks simply do not survive. This is why pinks are found overwhelmingly in small sizes, why high clarity is unusual in the color, and why a clean pink above two or three carats is a once-in-a-generation event. GIA's Tom Moses has observed that very few important pinks over twenty carats exist, and that it is unlikely we will see many more.
Geological Formation
Pink diamonds form under exceptional geological conditions:
- Depth: Formation occurs 90-120 miles beneath the Earth's surface
- Age: Most pink diamonds are 1.2-1.8 billion years old
- Pressure: Extreme tectonic forces create the necessary crystal deformation
- Rarity: The combination of factors required occurs in only a handful of locations globally
The Argyle deposit's unique geological history — including ancient tectonic collision events — created ideal conditions for pink diamond formation, explaining why this single source dominated global supply.
GIA Grading Scale
Pink diamond value increases dramatically with color intensity. The GIA (Gemological Institute of America) employs a standardized grading scale that assesses hue, tone, and saturation:
Faint Pink / Very Light Pink — Subtle pink tints visible under careful examination. Entry-level for collectors; more affordable but still rare.
Light Pink — Noticeable pink color that is immediately apparent. Good value proposition for jewelry use and emerging collectors.
Fancy Light Pink — Distinct pink coloration with clear saturation. Growing collector interest and strong appreciation potential.
Fancy Pink — Rich pink saturation with excellent color presence. Strong investment grade representing the minimum threshold for serious collectors.
Fancy Intense Pink — Exceptional color depth and saturation. Premium category commanding significant premiums and showing consistent appreciation.
Fancy Vivid Pink — The most prized classification; extraordinary rarity with pure, intense pink. These stones have achieved record auction prices and represent the pinnacle of the category.
Fancy Deep Pink — Concentrated, pure pink with exceptional depth. Extremely rare and highly sought after for their saturated color.
Our collection emphasizes Fancy, Fancy Intense, and Fancy Vivid grades — the stones most likely to hold value over time and maintain strong market liquidity.
Fancy Vivid Pink — Cushion Cut
Secondary Color Modifiers
Pink diamonds often display secondary hues that affect their character, appearance, and value:
Pure Pink — No secondary modifiers; the most valuable. Represents exceptional rarity as most pink diamonds show some secondary hue.
Purplish Pink — Purple undertones; highly desirable, particularly from Argyle. This modifier often enhances the romantic character of the stone.
Pink-Purple — More purple than pink; still beautiful and rare. Appeals to collectors seeking distinctive appearance.
Orangy Pink / Pink-Orange — Warm tones creating distinctive appearance. Less common than purple modifiers; offers unique aesthetic appeal.
Brownish Pink — Brown modifiers reduce value but provide more affordable entry point. These stones can still display beautiful color and offer accessibility for new collectors.
The most valuable pink diamonds show pure pink or purplish pink coloration with Vivid or Intense saturation. Argyle pink diamonds are particularly known for their distinctive purplish pink character.
Legendary Stones & Record Prices
Throughout history, exceptional pink diamonds have achieved legendary status and record-breaking prices, demonstrating their enduring collector appeal:
The CTF Pink Star (59.60 carats) — The largest internally flawless Fancy Vivid Pink ever graded by GIA. Found in 1999 as a 132.5-carat rough in De Beers' South African production, it took nearly two years to cut and was first shown as the Steinmetz Pink. It sold for $71.2 million at Sotheby's Hong Kong in 2017 — the highest price ever paid for any gemstone at auction — and was renamed by its buyer, Chow Tai Fook.
The Williamson Pink Star (11.15 carats) — A Fancy Vivid Pink cushion that sold for $57.7 million at Sotheby's Hong Kong in 2022: about $5.2 million per carat, the highest per-carat price ever paid for a diamond at auction.
The Winston Pink Legacy (18.96 carats) — Fancy Vivid Pink diamond with exceptional color purity and clarity, sold for about $50.4 million (roughly $2.6 million per carat) at Christie's Geneva in 2018. Held by the Oppenheimer family for over 50 years.
The Graff Pink (24.78 carats) — Fancy Intense Pink diamond that sold for $46 million at Sotheby's Geneva in 2010, holding the record for highest price per carat at that time. Laurence Graff later re-cut it to 23.88 carats to improve its clarity. This Type IIa stone exemplifies investment-grade quality.
The Eternal Pink (10.57 carats) — A Fancy Vivid Purplish Pink cushion that sold for $34.8 million at Sotheby's New York in 2023, a record for its color.
The Spirit of the Rose (14.83 carats) — Fancy Vivid Purple-Pink diamond that sold for $26.6 million in 2020 at Sotheby's Geneva, the largest purple-pink diamond ever offered at auction.
The Eden Rose (10.20 carats) — A flawless Fancy Intense Pink round brilliant — the rarest shape for the color — that sold for $13.3 million at Christie's New York in June 2024. The same month a 6.21-carat Fancy Vivid Pink oval realized $12 million at Phillips Geneva.
The Williamson Pink (23.60 carats) — Historic Fancy Pink diamond discovered in Tanzania in 1947, given to Queen Elizabeth II as a wedding gift. Later set in a brooch designed by Cartier, demonstrating pink diamonds' royal provenance.
The Daria-i-Noor (est. 175–186 carats) — A pale pink table-cut Golconda diamond and one of the largest pinks in existence, now a centerpiece of the Iranian Crown Jewels.
The Argyle Violet (2.83 carats) — Fancy Deep Grayish Bluish Violet diamond from the 2016 Argyle Tender, representing the rarest color variant from Argyle production.
These record prices underscore the extraordinary collector demand for top-quality pink diamonds. Explore all of these stones in our Famous Rare Diamonds of the World guide.
A Strong Long-Term Record
Pink diamonds have demonstrated a strong long-term record of value appreciation, establishing themselves as one of the better-performing tangible collectibles over the past two decades.
Landmark Auction Results
Historical Performance
- Pinks are the strongest long-term performers among fancy colors — the Fancy Color Research Foundation's index shows roughly +394% since 2005
- Most of that appreciation came between 2005 and 2014; the pink index has been broadly flat since, while the category as a whole has compounded at about 5.7% a year over twenty years
- Consistent auction records at Christie's, Sotheby's, Phillips, and regional houses
- Historically strong performance relative to other tangible collectibles, though results vary by stone
- Growing institutional recognition from wealth managers and family offices
These are cumulative multi-year figures, not annual returns. Performance varies significantly with color, size, quality, provenance, and the price paid at acquisition, and past performance does not guarantee future results.

Market Drivers
Permanent Supply Constraint — Argyle closure eliminated 90% of global pink diamond supply. No replacement source has been identified despite intensive exploration efforts worldwide.
No Alternative Sources — Current production from Brazil, southern Africa, Russia, Tanzania, and Canada totals fewer than 50 investment-grade stones annually — compared to several hundred from Argyle at peak.
Growing Asian Wealth — Increasing wealth in Greater China, particularly Hong Kong, has created strong collector demand; Asian buyers account for a large share of major pink diamond acquisitions at auction, and the Pink Star's 2017 sale in Hong Kong set the record for any auctioned work in Asia.
Currency Hedge & Portable Wealth — High-net-worth individuals increasingly view pink diamonds as wealth preservation tools that transcend currency fluctuations and geopolitical risks.
Celebrity & Royal Endorsements — High-profile pink diamond engagement rings and jewelry have driven consumer awareness and aspiration, supporting demand across all quality levels.
Institutional Recognition — Rare colored diamonds are increasingly recognised by wealth managers and family offices as a legitimate tangible asset class, with pink diamonds receiving particular emphasis given supply constraints.
Price Per Carat Progression
As with all colored diamonds, pink diamond values increase exponentially with size:
Price Ranges by Size
- 0.30-0.50 carats: $50,000-$150,000 per carat (Fancy Intense to Vivid)
- 0.50-1.00 carats: $100,000-$300,000 per carat
- 1.00-2.00 carats: $300,000-$800,000 per carat
- 2.00-5.00 carats: $800,000-$2 million per carat
- 5.00+ carats: $2 million+ per carat, with exceptional stones exceeding $3 million per carat
Future Outlook
Contracting Supply — As existing inventory depletes through private acquisitions and permanent collections, available supply continues to contract, which underpins the long-term scarcity case.
Sweet Spot: 0.50-3.00 Carat Range — This size range balances investment value with jewelry versatility, showing particularly strong liquidity and demand.
Argyle Provenance Premium — Stones with documented Argyle origin command 20-40% premiums and this gap is widening as the closure recedes into history.
Fancy Intense and Vivid Strongest — Top color grades continue to outperform, with Fancy Vivid stones achieving record prices at nearly every major auction.
Market Maturity — Pink diamond market has evolved from collector-driven to institutionally recognised, providing enhanced liquidity and price transparency.

Shape Impacts Color
The choice of shape significantly impacts a pink diamond's color appearance, value, and versatility. Fancy colors were cut much like colorless stones until the 1980s, when cutting trials on Argyle's steady production showed how facet design could intensify hue; pointed corners, split bezels, and deeper pavilions lengthen the light path and make color "pop" at the cost of weight. The radiant cut, devised by Henry Grossbard in 1976, was recognized early for holding color, which is why radiants and cushions dominate the pink market. Each shape offers distinct advantages:
Fancy Vivid Pink — Heart Shape
Cushion Cut Pink Diamonds
The most popular choice for pink diamonds, accounting for approximately 40% of the market. Cushion cuts maximize color saturation while providing excellent brilliance. The rounded corners and larger facets enhance the romantic character that makes pink diamonds so desirable. The Williamson Pink Star and Eternal Pink are both cushions.
Best for: Maximum color intensity with romantic, vintage appeal. Ideal for engagement rings and statement jewelry.
Size recommendation: Excellent at all sizes; particularly stunning from 0.75 carats and up.
Oval Cut Pink Diamonds
Elongated brilliance that enhances color while creating impressive visual presence. Oval cuts offer 10-15% more surface area than round diamonds of equivalent weight, maximizing apparent size. Our performance-cut ovals ensure exceptional light return without sacrificing color. The Pink Star itself is an oval.
Best for: Versatility across jewelry applications with strong color and elegant proportions.
Size recommendation: 0.50 carats and up; exceptional from 1.00 carat.
Radiant Cut Pink Diamonds
The brilliant facet pattern intensifies color while the cropped corners provide a modern aesthetic. Radiant cuts are excellent for maximizing color appearance in smaller carats, making them popular for both investment and jewelry purposes.
Best for: Modern styling with maximum color intensity per carat.
Size recommendation: Particularly effective in 0.50-2.00 carat range.
Heart Shape Pink Diamonds
The most romantic of all shapes, and among the most difficult to cut well. A fine heart requires perfect symmetry between the two lobes, a well-defined cleft, and proportions that avoid a squat or overly narrow outline. In pink diamonds the shape is especially prized, as the rounded lobes concentrate color beautifully while the point adds drama.
Best for: Collectors seeking a distinctive, unmistakably romantic stone.
Size recommendation: Minimum 0.50 carats; symmetry becomes far easier to appreciate from 1.00 carat.
Pear Shape Pink Diamonds
Elegant and distinctive, pear shapes showcase pink color magnificently while offering versatility for jewelry design. The elongated shape provides excellent color concentration at the point, creating dramatic visual impact. Popular for statement rings, pendants, and earrings.
Best for: Distinctive presence with romantic elegance.
Size recommendation: Minimum 0.40 carats; exceptional from 1.00 carat.
Emerald Cut Pink Diamonds
Step-cut faceting creates sophisticated, understated elegance. The broad table and open facets emphasize color purity and crystal clarity, making this shape ideal for stones with exceptional color saturation and minimal inclusions. Less common than brilliant cuts, emerald-cut pinks appeal to connoisseurs seeking refined aesthetics.
Best for: Understated elegance showcasing color purity. Collectors who appreciate Art Deco styling.
Size recommendation: Minimum 0.75 carats for optimal visual impact.
Round Brilliant Pink Diamonds
The most challenging to cut in pink diamonds, as the brilliant faceting can dilute color. This makes round brilliant pink diamonds extremely rare in Fancy Intense and Vivid grades, commanding significant premiums of 30-50% over other shapes of comparable quality. The flawless 10.20-carat Eden Rose, sold in 2024, shows what the shape can achieve.
Best for: Traditional engagement rings when color grade is Fancy Intense or Vivid. The ultimate in rarity.
Size recommendation: Due to color dilution, recommend only when color is Fancy Intense or Vivid.
Curated Argyle Inventory
We maintain a curated inventory of Argyle-certified pink diamonds with original Argyle grading documents and lot numbers. These stones carry historical significance and provenance premiums that increase each year following the mine's closure.
Argyle Certification Includes
- Original Argyle Pink Diamonds certificates with unique lot numbers
- Specific origin verification directly from the mine
- Full mining-to-market documentation and chain of custody
- Enhanced investment value from documented provenance
- Collectibility beyond intrinsic gem value
- Historical significance as pieces of mining history
Argyle Color Character
Argyle pink diamonds are known for their distinctive characteristics:
- Purplish-pink undertones — Signature Argyle color character
- Even color distribution — Consistent saturation throughout the stone
- Exceptional cutting quality — Argyle maintained strict standards for stones bearing their certificates
- Smaller average sizes — Argyle rarely produced stones over 2 carats, making larger examples extraordinary
Investment Considerations
Argyle-certified pink diamonds currently command 20-40% premiums over comparable non-Argyle stones, and this premium gap has widened as the closure becomes more distant and remaining Argyle inventory depletes. For investment-focused acquisitions, Argyle provenance adds an additional layer of documented provenance and value preservation.
Nature's Rarest Combination
Some pink diamonds are also classified as Type IIa — the purest category of diamond, accounting for less than 2% of all natural diamonds. Type IIa designation indicates the diamond contains virtually no nitrogen impurities, resulting in exceptional optical properties.
Type IIa Characteristics
- Exceptional Optical Clarity — Superior light transmission and transparency
- Enhanced Transparency — Allows deeper visual penetration into the stone
- Superior Light Performance — Maximizes brilliance and fire
- Scientific Interest — Represents the purest diamond crystal structure
- Elevated Investment Value — Commands premiums of 15-25% over Type Ia equivalents
- Historical Significance — Many famous diamonds are Type IIa, including the Koh-i-Noor
When available, we prioritize Type IIa pink diamonds for their superior quality characteristics and enhanced collector appeal. The combination of pink color (already extremely rare) with Type IIa purity represents one of nature's rarest gemological occurrences.
Verification Process
Type IIa classification is verified through:
- Infrared spectroscopy confirming absence of nitrogen
- GIA reports specifically noting Type IIa designation
- Independent laboratory confirmation when requested
- Full scientific documentation provided with purchase

Strengthening Fundamentals
The pink diamond market continues to strengthen, driven by fundamental supply-demand dynamics that favor long-term value retention.
Recent Market Trends
Strong Sustained Demand for 0.50-2.00 Carat Range — This size range shows particularly strong liquidity, with typical market time of 3-6 months for well-priced stones. Larger stones (2-5 carats) require longer marketing but command exponential premiums.
Market Dynamics
Cushion and Oval Cuts Showing Particular Strength — These shapes account for 70% of recent auction sales, with cushion cuts commanding slight premiums due to optimal color retention.
Argyle-Certified Stones Commanding 20-40% Premiums — The premium gap continues to widen as the 2020 closure becomes more distant and remaining Argyle inventory depletes through permanent acquisitions.
Asian Buyers Increasingly Active — Greater China buyers account for a large share of pink diamond acquisitions over 1.00 carat at major auctions, providing strong market depth and liquidity.
Limited Availability Creating Competitive Bidding — Recent auctions have seen strong sell-through rates for investment-grade pink diamonds, with many lots exceeding high estimates.
Investment Funds and Family Offices Adding Allocation — Institutional recognition has grown significantly, with rare colored diamonds — pinks especially, given supply constraints — increasingly treated as a legitimate tangible asset class.
Price Outlook
Market fundamentals underpin the long-term scarcity case:
- Permanent 90% supply reduction from Argyle closure
- No replacement sources identified despite extensive exploration
- Growing global collector base, particularly in Asia
- Increasing institutional acceptance
- Strong long-term historical track record
- Supply constraints intensifying as inventory depletes
- Celebrity and royal endorsements maintaining consumer awareness
The closure of the Argyle mine removed the primary global source of pink diamonds, and with no replacement identified, the long-term scarcity case is unusually strong — though future performance is never guaranteed and depends heavily on quality, size, provenance and acquisition price. Argyle-certified stones continue to command a premium over comparable non-Argyle pinks. Our VIP advisory team provides market updates and honest, stone-by-stone assessments to clients.
Are pink diamonds a good investment?
Pinks have been the strongest long-term performers among fancy color diamonds — the FCRF index shows roughly +394% since 2005, though most of that gain came before 2014 — and the permanent closure of Argyle, which produced around 90% of global supply, has created genuine and lasting scarcity. Performance is not a straight line and never guaranteed: recent years have been steadier than earlier decades, and results vary significantly with color, size, quality, provenance and the price paid. Pink diamonds are best understood as long-term collectible assets (5-10+ years) with documented auction markets. How much to allocate is a personal decision best made with your own financial advisors.
How do I verify a pink diamond's authenticity?
Genuine pink diamonds must be certified by GIA with detailed color grading. The GIA report can be verified online using the report number at GIA.edu. Argyle-certified stones include original Argyle certificates that can be verified through dealer networks. We provide additional documentation and lifetime authenticity guarantees. Beware of treated diamonds — GIA reports clearly indicate any treatments, but we sell only natural, untreated pink diamonds.
What size pink diamond should I consider?
For investment purposes, we recommend minimum 0.50 carats, with 1.00+ carats offering optimal liquidity. The 0.50-2.00 carat range balances investment value with jewelry versatility and market depth. Larger stones (3+ carats) are exceptional acquisitions but require higher capital allocation and longer marketing periods at eventual sale.
How long does it take to sell a pink diamond?
Through major auction houses, the process typically takes 4-6 months from consignment to sale. Private sales can be faster (2-4 months) but may require price flexibility. Our resale support services assist clients with both channels. The 0.50-2.00 carat range in Fancy Intense and Vivid grades shows fastest liquidity.
Should I prioritize Argyle-certified stones?
Argyle-certified pink diamonds currently command 20-40% premiums and this gap is widening. For investment-focused purchases, Argyle provenance adds documented provenance and value preservation. For jewelry-focused purchases, non-Argyle stones can offer better value if color and quality meet your standards. We help clients evaluate the cost-benefit of Argyle certification based on individual objectives.
What is the difference between Type IIa and regular pink diamonds?
Type IIa pink diamonds contain virtually no nitrogen, making them the purest diamond crystal structure (less than 2% of all diamonds). This results in superior optical properties — enhanced transparency, light performance, and visual appeal. Type IIa designation adds 15-25% premiums and provides additional collector interest and collectibility.
How do pink diamonds compare to other colored diamonds?
Pink diamonds have shown stronger long-term appreciation than yellow and most other colors, exceeded only by certain rare reds — the rarest of all fancy colors, with fewer than 30 true reds known to exist worldwide and only a handful above two carats. The Argyle closure created unique supply dynamics favoring pink diamonds. Blues command higher per-carat prices in top grades and were the standout color of 2025, but pinks offer broader market depth and liquidity across the size spectrum.
Fancy Red — Square Radiant · The Rarest Fancy Color
Can pink diamonds be worn daily?
Yes, with proper settings. Diamonds are the hardest natural substance and highly resistant to scratching and wear. Secure platinum or high-karat gold settings with regular annual inspections ensure safe daily wear. Many clients wear investment-grade pink diamonds regularly in fine jewelry while maintaining comprehensive insurance coverage.
What is "plastic deformation" that causes pink color?
Plastic deformation refers to permanent changes in the diamond's crystal lattice caused by enormous stress during formation. This creates microscopic structural distortions that selectively absorb certain wavelengths of light, resulting in pink color. Unlike chemical impurities (which cause blue and yellow), pink results from physical crystal structure changes, making it scientifically unique and rare.
