Pink Star Diamond Price Breakdown: Why It Sold for $71 Million
The Pink Star diamond price broke world records when Hong Kong jeweler Chow Tai Fook paid $71.2 million ($71,175,926) at Sotheby’s Hong Kong on April 4, 2017, making it the most expensive diamond, gemstone, or jewel ever sold at auction. The 59.60-carat oval mixed-cut diamond is the largest Fancy Vivid Pink Internally Flawless diamond ever graded by the Gemological Institute of America, and the per-carat price reached $1,194,227. The price was driven by a combination of unmatched size, the rarest possible color and clarity grades, and the fact that pink diamonds of any meaningful size are statistically among the most scarce gemstones on Earth.
In our market observations across diamond pricing and the high-end colored stone market, the Pink Star price is one of the most studied data points in modern auction history. Experience has shown that understanding why this diamond reached $71.2 million teaches more about the real economics of fine diamonds than any other single transaction in the past 50 years.
Pink Star Diamond Price at a Glance
Before diving into the breakdown, here are the essential facts every diamond enthusiast should know.
Attribute | Detail |
Final auction price | $71.2 million ($71,175,926 USD) |
Auction date | April 4, 2017 |
Auction house | Sotheby’s Hong Kong |
Carat weight | 59.60 carats (11.92 g) |
Price per carat | $1,194,227 |
Color grade | Fancy Vivid Pink (GIA highest pink grade) |
Clarity grade | Internally Flawless (IF) |
Cut | Oval mixed cut |
Diamond type | Type IIa (chemically purest) |
Original rough | 132.5 carats |
Mine origin | De Beers, South Africa, 1999 |
Cutting time | 20 months |
Original name | Steinmetz Pink (2003) |
Current owner | Chow Tai Fook (renamed CTF Pink Star) |
Approximate size | About the size of a strawberry |
A key insight often overlooked: the Pink Star’s $1.19 million per-carat price was actually below the prevailing per-carat market price for comparable Fancy Vivid pink diamonds at the time. The world record was set by total price because of the diamond’s exceptional size, not because the per-carat figure was unusually high.
Why the Pink Star Diamond Reached $71 Million
The Pink Star price was not arbitrary. It reflects six interlocking factors that combined to make this stone genuinely unique.
The six factors driving the Pink Star diamond price:
- Carat weight: at 59.60 carats, the largest Fancy Vivid Pink ever graded
- Color grade: Fancy Vivid Pink, the highest possible pink color saturation
- Clarity grade: Internally Flawless, the rarest clarity at this size
- Diamond type: Type IIa, chemically pure, less than 2% of all diamonds
- Provenance: De Beers South Africa origin, Smithsonian exhibition history
- Auction context: three-bidder competition at Sotheby’s Hong Kong
Experience has shown that no single factor justified the $71 million price. The combination of all six in one stone is what made the Pink Star price record-breaking.
The Pink Diamond Rarity Equation
To understand the Pink Star diamond price, you have to understand how rare pink diamonds actually are.
The Argyle Mine Story
For the past 30 years, the Argyle mine in Western Australia supplied approximately 80% of the world’s pink diamonds. The mine produced around 20 million carats of diamonds annually. Of that output, only about 0.1% were classified as pink diamonds, and only a tiny fraction of those were larger than a few carats.
The Argyle mine was depleted and closed permanently in 2020. Since then, the global supply of pink diamonds has become even more constrained, putting upward pressure on every pink diamond transaction in the secondary market.
The Numbers That Make Pink Diamonds Special
A key insight often overlooked: only about 1 in 10,000 diamonds is naturally colored, and pink diamonds represent a small fraction of those. Among naturally pink diamonds, the percentage that achieve Fancy Vivid Pink color is even smaller. The percentage that exceeds 5 carats is still. The percentage that are also Internally Flawless is statistically near zero.
The Pink Star sits at the intersection of all four of these scarcity layers. It is, mathematically, one of the rarest diamonds ever assessed.
The Pink Star Diamond Auction History
The 2017 sale was not the Pink Star’s first auction appearance. The full transaction history shapes its current price reality.
2013: The First Auction Failure
In November 2013, the Pink Star was offered at Sotheby’s Geneva and sold for an apparent $83 million to New York-based diamond cutter Isaac Wolf. The sale set what would have been the world record at the time.
However, Wolf defaulted on the payment. Sotheby’s months later disclosed in its 2014 earnings report that the transaction had collapsed. Because Sotheby’s had provided a $60 million guarantee on the diamond, the auction house was forced to acquire it from the seller (Steinmetz Diamonds).
The diamond was briefly renamed the “Pink Dream” by Wolf before reverting to Pink Star.
2017: The Successful Auction
On April 4, 2017, Sotheby’s offered the Pink Star again at its Hong Kong auction. Three bidders competed for the stone. Henry Cheng Kar-Shun, chairman of Chow Tai Fook Enterprises, placed the winning bid by phone at a hammer price of $63 million.
After Sotheby’s buyer’s premium, the total final price reached $71,175,926 — approximately HK$553 million.
Cheng renamed the diamond the CTF Pink Star in honor of his father, company founder Cheng Yu-Tung, and to commemorate Chow Tai Fook’s 88th anniversary. The 88 number in Chinese culture symbolizes prosperity and good fortune.
Why Hong Kong Was the Right Auction Venue
In our market observations, Sotheby’s strategic decision to move the second auction from Geneva to Hong Kong was deliberate. By 2017, Hong Kong had become the global epicenter for ultra-high-net-worth Asian collectors. The auction also followed Art Basel Hong Kong, which concentrated wealthy international buyers in the city.
A key insight often overlooked: high-end diamond auctions are increasingly tied to where the world’s billionaires are physically gathering, not just to traditional Western auction centers.
Per-Carat Pricing: Where the Pink Star Fits
While the $71.2 million total price was a world record, the per-carat figure offers a more nuanced view of the Pink Star diamond price in market context.
Diamond | Carats | Total Price | Price per Carat |
Williamson Pink Star (2022) | 11.15 | $57.7M | $5,178,124 |
Blue Moon of Josephine (2015) | 12.03 | $48.4M | $4,028,941 |
Oppenheimer Blue (2016) | 14.62 | $57.5M | $3,932,000 |
Winston Pink Legacy (2018) | 18.96 | $50.7M | $2,673,000 |
Pink Star / CTF Pink (2017) | 59.60 | $71.2M | $1,194,227 |
Graff Pink (2010) | 24.78 | $46.2M | $1,864,221 |
Princie Diamond (2013) | 34.65 | $39.3M | $1,134,209 |
Pink Promise (2017) | 14.93 | $32.5M | $2,178,000 |
Experience has shown that the Pink Star’s per-carat price was actually below several smaller pink diamonds. This reflects an auction reality: at extreme carat weights, even billionaire collectors face per-carat sticker resistance, since the absolute total dollar figures become limiting even for the wealthiest buyers.
Anatomy of the Pink Star: The Cutting Story
To understand the Pink Star diamond price, you need to appreciate what it took to create the stone in the first place.
From 132.5-Carat Rough to 59.60-Carat Polished
The original rough diamond weighed 132.5 carats when De Beers extracted it from a South African mine in 1999. Steinmetz Diamonds purchased the rough and committed to a 20-month cutting and polishing process.
This is an extraordinarily long cutting timeline. For context, most fine diamonds are cut in 6 to 12 weeks. The Pink Star took nearly two years because:
- Every facet had to maximize the visible vivid pink color
- A single misjudgment could have destroyed the Internally Flawless clarity
- Each cut decision balanced final weight against optical impact
- The team needed to study the rough for months before any cutting began
The result was a 59.60-carat oval mixed-cut diamond, representing approximately 45% of the original rough weight. This yield is generous for a colored diamond of this size and quality.
The 2003 Smithsonian Exhibition
After cutting, the Pink Star (then called the Steinmetz Pink) was unveiled in Monaco on May 29, 2003, in a public ceremony. It then traveled to Washington, D.C., where the Smithsonian National Museum of Natural History exhibited it as part of “The Splendor of Diamonds” alongside the De Beers Millennium Star, the Heart of Eternity, and other legendary stones.
This exhibition history adds significant provenance value. Museum-grade exhibition is one of the strongest public-record signals a private diamond can carry into auction.
Comparison: Pink Star Diamond Price vs. Other Famous Diamonds
How does the Pink Star price compare to other legendary diamonds?
Diamond | Carats | Notable Price/Value | Status |
Pink Star | 59.60 | $71.2M (2017 sale) | Privately owned, Chow Tai Fook |
Hope Diamond | 45.52 | ~$250M (estimated) | Smithsonian, not for sale |
Cullinan I | 530.20 | $400M+ (estimated) | British Crown Jewels |
Koh-i-Noor | 105.60 | $200-400M (estimated) | British Crown Jewels |
Williamson Pink Star | 11.15 | $57.7M (2022 sale) | Private collection |
Oppenheimer Blue | 14.62 | $57.5M (2016 sale) | Private collection |
Winston Pink Legacy | 18.96 | $50.7M (2018 sale) | Harry Winston |
Graff Pink | 24.78 | $46.2M (2010 sale) | Graff Diamonds |
In our market observations, the Pink Star price set the practical ceiling for what a single jewel can achieve at public auction. Beyond approximately $75 million, ultra-high-end diamonds tend to sell privately rather than publicly to avoid the constraints of even the most aggressive bidding rooms.
What the Pink Star Price Teaches Diamond Buyers
For buyers thinking about diamonds at any budget level, the Pink Star price tells a story about value drivers that scale down to engagement-ring purchases.
Five lessons from the Pink Star auction:
- Color rarity drives value more than carat at the top of the market. A 59.60-carat colorless diamond is rare. A 59.60-carat Fancy Vivid Pink Internally Flawless is functionally unique.
- Clarity at large sizes is exponentially scarce. Maintaining Internally Flawless clarity in a 59.60-carat stone is much harder than in a 1-carat diamond. The clarity premium grows rapidly with size.
- Type IIa designation indicates investment-grade chemistry. Less than 2% of diamonds are Type IIa, the chemically purest category. The Pink Star is Type IIa, which is part of the price story.
- Provenance documentation accelerates appreciation. The Smithsonian exhibition, Sotheby’s auction history, and named ownership chain all add value beyond the physical stone itself.
- Cutting craftsmanship is part of the price. A 20-month cutting timeline is genuinely rare. Master cutting work that maximizes color and clarity is reflected in the final hammer price.
A key insight often overlooked: these same five factors apply, in scaled-down form, to every quality diamond purchase. Color, clarity, type, provenance, and cutting craftsmanship are universal value drivers from $5,000 engagement rings to $71 million world-record stones.
Expert Analysis: Five Truths About the Pink Star Diamond Price
In our market observations across diamond pricing and the high-end colored gem market, the Pink Star price reveals five patterns that shape the entire fine diamond economy.
Five insights from the auction record:
- Pink diamond prices have outpaced inflation dramatically. Comparable pink diamonds 20 years ago sold for fractions of today’s prices. Argyle’s 2020 closure has only accelerated the trend.
- The auction failure of 2013 created the 2017 opportunity. Isaac Wolf’s default actually cemented the Pink Star’s mystique. By the 2017 auction, the diamond carried both Steinmetz cutting heritage and a famous failed-sale story.
- Hong Kong is the new diamond auction capital. Three of the past five record-breaking diamond sales have happened at Sotheby’s Hong Kong. Geneva and New York remain important, but the largest checks are increasingly written from Asia.
- Per-carat records are different from total price records. The Pink Star holds the total price record. The Williamson Pink Star (2022) holds the per-carat record at $5.18 million per carat. Both are useful benchmarks for different purposes.
Fancy Vivid Pink IF is a category of one. Experience has shown that no other diamond at the Pink Star’s combination of size, color, and clarity is known to exist outside of museum holdings. The market accepts that the Pink Star is genuinely unique.
How Diamond Experts Evaluate Fancy Color Pricing
When evaluating any high-end colored diamond, experienced professionals analyze:
- Color grade: Fancy, Fancy Intense, Fancy Vivid (vivid is the highest)
- Color origin: natural vs. treated (natural commands a 5-10x premium)
- Color modifiers: pure pink vs. orangish-pink vs. purplish-pink (pure is most valuable)
- Carat weight: with steep premiums above benchmark sizes (10ct, 25ct, 50ct)
- Clarity at carat weight: IF and VVS clarity grades at large sizes are exponentially rare
- Type designation: Type IIa diamonds command meaningful premiums
- GIA documentation: any high-value colored diamond should carry a current GIA report
- Provenance: museum exhibitions, named ownership, auction history
For buyers at any level engaging with colored diamonds, working with a GIA-certified diamond expert is essential. The pricing variables in colored diamonds are far more complex than in colorless stones.
Frequently Asked Questions About Pink Star Diamond Price
Why did the Pink Star diamond sell for $71 million?
The Pink Star sold for $71.2 million at Sotheby’s Hong Kong in April 2017 because it combined six rare attributes in one stone: 59.60 carats (the largest Fancy Vivid Pink ever graded), Fancy Vivid Pink color (the highest possible saturation), Internally Flawless clarity, Type IIa chemistry (chemically pure), provenance from a 1999 De Beers South African discovery, and museum-grade exhibition history at the Smithsonian. No other known diamond combines all six factors at this scale.Who owns the Pink Star diamond now?
The Pink Star is owned by Chow Tai Fook Enterprises, a Hong Kong-based luxury jewelry company that purchased it at the 2017 Sotheby’s auction. The company renamed the stone the CTF Pink Star in honor of company founder Cheng Yu-Tung and the brand’s 88th anniversary. It is held privately and is not on public display.Why is the Pink Star so much more expensive than larger diamonds like the Cullinan?
Total carat weight is only one variable in diamond pricing. Pink diamonds are dramatically rarer than colorless diamonds, and Fancy Vivid Pink is the rarest pink color grade. The Pink Star achieved its $71.2 million price because color rarity drives value more powerfully than size at the top of the diamond market. The Cullinan diamonds in the British Crown Jewels are larger but colorless, which places them in a different valuation category.What was the previous Pink Star auction in 2013?
In November 2013, the Pink Star was offered at Sotheby’s Geneva and received a winning bid of $83 million from New York diamond cutter Isaac Wolf. However, Wolf defaulted on the payment. Sotheby’s, which had provided a $60 million guarantee, was forced to acquire the diamond. It was re-offered in 2017 at the Hong Kong auction where Chow Tai Fook successfully purchased it for $71.2 million.How rare are pink diamonds compared to other colored diamonds?
Pink diamonds are among the rarest colored diamonds in the world. For 30 years, the Argyle mine in Western Australia supplied approximately 80% of global pink diamonds, with only 0.1% of its 20 million carat annual output classified as pink. The Argyle mine closed permanently in 2020, further constraining global supply. Among pink diamonds, achieving Fancy Vivid color and Internally Flawless clarity at any meaningful size is statistically near-impossible.
