Stones That Changed History
Some diamonds end up on fingers. These ones ended up in history books, crown jewels, Smithsonian display cases, and the occasional Canadian bank vault.
What makes a diamond legendary is never just its size or its clarity. It is the journey - the empires it passed through, the hands that held it, the conflicts it sparked, and the extraordinary coincidences that kept it from being lost forever. Most of the stones on this list began in the same place: the ancient alluvial riverbeds of India's Golconda region, which for thousands of years was the only place on earth where diamonds had ever been found.
Here are the 20 most remarkable, most storied, and most extraordinary diamonds ever known.
1. The Cullinan Diamonds — 3,106 ct | South Africa | 1905
The largest gem-quality rough diamond ever found - roughly the size of a human heart, over a pound in weight. Discovered on January 26, 1905, at the Premier Mine in South Africa, it was so large that the mine manager's office nearly threw it away as worthless crystal. Cut by Joseph Asscher's workshop in Amsterdam in 1908 into nine major stones and 96 smaller brilliants, the Cullinan I (530 ct pear, the largest colourless cut diamond in the world) sits in the British Sovereign's Sceptre, and Cullinan II (317 ct cushion) in the Imperial State Crown. Queen Mary called the smaller stones 'Granny's chips.' South Africa has periodically renewed calls for their return.
2. The Koh-i-Noor — 105.6 ct | India (Golconda tradition) | Origin disputed
'Mountain of Light.' The most travelled and most contested diamond in the world. Its solid documented history begins in Mughal India in the 1740s, when it was among the treasures Nader Shah of Persia looted from Delhi. It passed to the Sikh Empire, then to the British Crown following the 1849 Treaty of Lahore - signed in the name of a ten-year-old boy, which is precisely why India, Pakistan, and Afghanistan all still dispute its legitimacy. Set only in the crowns of British queens and queens consort, it was quietly left out of Queen Camilla's coronation crown in 2023, replaced by Cullinan stones, amid continued repatriation controversy.
3. The Hope Diamond — 45.52 ct | India (Golconda) | Current: Smithsonian
The world's most famous 'cursed' gem - and the Smithsonian's own longtime curator says the curse isn't real. A deep greyish-blue Type IIb diamond, it was brought from Golconda to France by the gem merchant Jean-Baptiste Tavernier in 1668, sold to Louis XIV, stolen during the French Revolution, and resurfaced in London recut and unrecognisable. Pierre Cartier spun an elaborate curse story in 1910 specifically to persuade Washington socialite Evalyn Walsh McLean to buy it. Harry Winston donated it to the Smithsonian in 1958 - sent via ordinary registered post. Insured today at an estimated US$250 million.
4. The Regent Diamond — 140.64 ct | India (Golconda) | Current: The Louvre
Widely regarded as the most perfectly cut large diamond to survive from the 18th century. Cut in London over two years from a 410 ct rough found in India around 1698, it was eventually purchased in 1717 by Philippe d'Orleans for the French Crown. It adorned the coronation crowns of Louis XV and Louis XVI, Marie Antoinette's hat, and Napoleon's sword. When the Third Republic auctioned most of the French Crown Jewels in 1887 to undercut royalist sentiment, the Regent was judged too historically important to sell and went instead to the Louvre, where it has remained ever since. Estimated value: over US$60 million.
5. The Orlov Diamond — 189.62 ct | India (Golconda) | Current: Moscow Kremlin
A magnificent high-domed rose cut with a faint blue-green tinge, described by the French gem merchant Tavernier in 1665. Count Grigory Orlov reportedly gave it to Empress Catherine the Great hoping to win back her favour after their relationship had cooled - she accepted the stone but not the proposal. Mounted at the top of the Russian Imperial Sceptre in 1774, it remains one of the great surviving treasures of the Romanov dynasty in the Kremlin's Diamond Fund today.
6. The Sancy Diamond — 55.23 ct | India (Golconda) | Current: The Louvre
A pale yellow pear-shaped double rose cut that survived the French Revolution, two royal dynasties, and forty years of unexplained disappearance. Its notable owners read like a European history syllabus: Henri III and IV of France, James I and Charles I of England, Cardinal Mazarin, Louis XIV, and Marie Antoinette. Stolen in 1792, it vanished for decades before resurfacing with the Demidov family in Russia, then an Indian prince, then the Astor family. France bought it back in 1978 and it joined the Regent in the Louvre's Apollo Gallery.
7. The Dresden Green Diamond — 40.70 ct | India (Golconda) | Current: Dresden, Germany
The largest known natural green diamond in the world - its extraordinary colour created by ancient exposure to natural radiation over millions of years. Purchased at the Leipzig Fair in 1741 by Friedrich Augustus II of Saxony, it has anchored Saxony's royal treasury for nearly 300 years. Its closest brush with loss came the night of 25 November 2019, when thieves broke into the Green Vault in what became Germany's largest jewellery theft - the Dresden Green survived only because it was on loan to the Metropolitan Museum of Art in New York at the time.
8. The Florentine Diamond — 137.27 ct | India | Current: Quebec bank vault
One of the most remarkable diamond news stories of the last decade - and it happened in November 2025. The Florentine, a light yellow 9-sided 126-facet double rose cut in the Habsburg collection since 1737, disappeared after World War I when the last Habsburg emperor took it into exile and the trail went cold for over a century. For decades, historians speculated it had been stolen, secretly recut, or smuggled out of Europe. On November 6, 2025, descendants of the last Habsburg empress revealed the truth: the diamond had been sitting safely in a bank vault in Quebec since World War II. The family is now planning to display it in a Canadian museum - in gratitude for Canada taking them in as refugees.
9. The Darya-i-Noor & Noor-ul-Ain — ~182 ct + ~60 ct | India (Golconda) | Current: Tehran
Iran's two great pink diamonds - most likely cut from the same enormous Mughal rough stone, possibly the 242 ct 'Great Table Diamond' described by Tavernier in 1642. Both were almost certainly part of the Mughal treasury before Nader Shah of Persia looted them in his 1739 sack of Delhi, alongside the Koh-i-Noor. Unlike the Koh-i-Noor, they never left Persia and remain today in Iran's National Jewels collection at the Central Bank of Tehran - a reminder that not every great Indian diamond ended up in a European crown.
10. The Shah Diamond — 88.6 ct | India (Golconda) | Current: Moscow Kremlin
One of the only famous diamonds ever literally signed by its owners. Three successive rulers - Mughal, Persian, and Qajar - engraved their names and the dates of their ownership directly onto the stone's surface, creating a unique living historical document carved into one of the hardest materials on earth. It reached Russia in the 19th century as part of reparations following the killing of the Russian ambassador in Tehran in 1829, and remains in the Kremlin's Diamond Fund today.
"Every great diamond in this list began as light trapped in carbon, deep in the earth. What made each one legendary was the human story that followed."
11. The Spoonmaker's Diamond — 86 ct | Ottoman Empire | Current: Topkapi Palace, Istanbul
The most valuable object in the Ottoman imperial treasury - a pear-shaped D colour diamond surrounded by 49 old-mine-cut diamonds in a silver setting described as 'a full moon lighting a starry sky.' Its most famous legend holds that a poor man found it in a rubbish heap and traded it to a spoon-maker for three wooden spoons, not knowing its value. A more historically grounded account ties it to Napoleon's mother. On permanent display at Topkapi Palace Museum, it has been the star exhibit of the Imperial Treasury for centuries.
12. The Tiffany Yellow Diamond — 128.54 ct | South Africa | Current: Tiffany & Co., New York
The most famous diamond that has never been sold. Found in the Kimberley Mines of South Africa in 1877, it was cut by Tiffany's founding gemologist George Kunz in Paris into 82 facets specifically designed to maximise its fire - and Tiffany & Co. has simply never parted with it since. In 145 years, it has been worn publicly by fewer than six women: Audrey Hepburn (for Breakfast at Tiffany's promotional photographs in 1961), Lady Gaga (2019 Oscars), Beyonce (2021), and a small handful of others. Its market value has never been tested by a sale and remains entirely speculative.
13. The Taylor-Burton Diamond — 69.42 ct | South Africa | Current: Mouawad collection
The diamond that made one million dollars a publicly meaningful number. Found at the Premier Mine in 1966 and cut by Harry Winston, it became the first diamond ever publicly sold for over US$1 million when Cartier won it at auction in 1969. Richard Burton, the under-bidder, phoned Cartier the next day and bought it back for $1.1 million on the condition that it first tour Cartier's New York and Chicago stores - where 6,000 people a day queued to see it. Elizabeth Taylor wore it to Princess Grace of Monaco's 40th birthday. She sold it in 1978 for $5 million, donating proceeds to build a hospital in Botswana.
14. The Centenary Diamond — 273.85 ct | South Africa | Current: Private
The largest top-colour, externally and internally flawless diamond ever cut - a D Flawless modified heart shape of extraordinary rarity. Found at the Premier Mine in 1986 (kept secret for two years), it was cut largely by hand by master cutter Gabi Tolkowsky over nearly three years, in a vibration- and temperature-controlled underground room, specifically to avoid any heat or shock damage. The first 154 days of work removed just 50 carats of cracked material. Unveiled at the Tower of London in 1991 and insured for over US$100 million, its current private owner is undisclosed.
15. The Wittelsbach-Graff Diamond — 31.06 ct | India (Golconda tradition) | Current: Qatar
A deep blue Type IIb diamond in Habsburg and Bavarian royal collections since the 17th century - and the subject of one of the most controversial decisions in modern gem history. Sold at Christie's in 2008 to jeweller Laurence Graff for US$24.3 million, Graff chose to recut the centuries-old stone to remove surface imperfections and improve its clarity grade - effectively destroying its visible historical patina for a commercial gain. Historians and gemologists sharply criticised the decision. The stone resold privately in 2011 to the then-Emir of Qatar for a reported US$80 million.
16. The CTF Pink Star — 59.60 ct | De Beers, 1999 | Current: Chow Tai Fook
The all-time auction record holder for any diamond or jewel of any kind - a title it has held since April 2017. A fancy vivid pink oval of internal flawless clarity, it was found by De Beers in 1999 as a 132 ct rough and cut over two years. At Sotheby's Hong Kong on April 4, 2017, a five-minute three-way phone bidding war ended with Hong Kong billionaire Henry Cheng Kar-Shun taking it for HK$553 million - US$71.2 million. He renamed it the CTF Pink Star in memory of his late father, the founder of the Chow Tai Fook jewellery empire.
17. The Oppenheimer Blue — 14.62 ct | Unknown | Current: Private
Held the all-diamond auction record for exactly one year - May 2016 to April 2017, when the CTF Pink Star surpassed it. A rectangular fancy vivid blue from the collection of Sir Philip Oppenheimer, who chaired De Beers' Central Selling Organisation for 45 years, it sold at Christie's Geneva in May 2016 for US$57.5 million after a 20-minute bidding war between two phone bidders. Fewer than 0.0001% of all diamonds mined are blue - which explains why blue diamonds have produced so many of this generation's records.
18. The Blue Moon of Josephine — 12.03 ct | Cullinan Mine, 2014 | Current: Private
Cut from a 29.6 ct rough found at the Cullinan Mine in 2014, this fancy vivid blue internally flawless cushion sold at Sotheby's Geneva in November 2015 for US$48.4 million - then the highest per-carat price ever achieved for a diamond at $4.02 million per carat. Hong Kong billionaire Joseph Lau bought it and named it for his young daughter Josephine - one day after buying her a separate pink diamond he named 'Sweet Josephine.' Both names have stayed in the trade ever since.
19. The Lesedi La Rona — 1,109 ct rough | Botswana, 2015 | Current: Graff Diamonds
The second-largest gem-quality rough diamond ever found - at 1,109 carats, the largest discovered in over a century, surpassed only by the 1905 Cullinan. Its name means 'Our Light' in Tswana, chosen via a public competition open to all Botswana citizens. After failing to sell at a 2016 Sotheby's auction (the reserve wasn't met), it sold privately to Graff for US$53 million. Graff spent 18 months developing custom scanning software just to plan the cut, ultimately producing the 302.37 ct Graff Lesedi La Rona - the world's largest square emerald-cut diamond - plus 66 additional polished stones.
20. The Constellation — ~813 ct rough | Botswana, 2015 | Current: Private
Found days before the Lesedi La Rona at the same Karowe Mine in Botswana in November 2015, the Constellation sold at auction in May 2016 for US$63.1 million - then the record price ever paid for a rough diamond. What makes it scientifically fascinating: GIA researchers believe several large rough stones recovered at Karowe that week - including the Lesedi La Rona, the Constellation, and several others - may all be fragments of a single, even larger original diamond. If true, the stone these twenty were once part of would be among the largest ever found. That question remains genuinely unresolved.
The Thread That Runs Through All of Them
If you read through this list carefully, one pattern is impossible to miss. The majority of the world's most famous, most historically significant, most coveted diamonds share a single origin: the ancient Golconda mines of India.
The Hope Diamond. The Koh-i-Noor. The Regent. The Orlov. The Sancy. The Dresden Green. The Shah. The Darya-i-Noor. The Spoonmaker's. All Indian stones. All shaped, at some point, by Indian hands.
The western world has spent centuries wearing India's diamonds while rarely crediting India with producing them. This is the history that Stara's founder Dev Katrodiya grew up inside - the son of a family that has spent over forty years on the Surat cutting floor where the great majority of the world's diamonds, famous or not, still take their final form.
When you choose Stara, you are not just choosing a ring. You are choosing a jeweller whose connection to this history is not studied but lived.
