Some jewelry costs more than a house. Some costs more than a hundred houses. When a single ring sells for $57 million, it is easy to assume the number is a typo, but auction houses like Christie’s and Sotheby’s keep detailed public records of these sales, and the prices are very real. Because these pieces almost never appear twice, each sale becomes a small piece of history, watched by collectors, museums, and jewelers around the world who want to understand exactly what pushed the price so high.
What Is the Most Expensive Piece of Jewelry Ever Sold?
The record for the most expensive jewel ever sold at auction belongs to the Pink Star, a 59.60-carat pink diamond that sold for $71.2 million in 2017. That works out to roughly $1.2 million for every carat, making it the most expensive gemstone ever sold at auction, in any color or shape.
The stone started out as a 132.5-carat rough diamond, mined in South Africa in 1999 by De Beers. Cutting it took nearly two years, because pink diamonds are graded not just on size but on how deep and even their color looks once cut, and the cutters at Steinmetz Diamonds worked slowly to protect that color instead of rushing for extra carats. The result was unveiled in 2003 as the “Steinmetz Pink,” a stone the Gemological Institute of America graded Fancy Vivid Pink, the top color grade possible, and Internally Flawless, meaning no visible flaws at all. No other pink diamond has ever earned both grades at this size.
The Pink Star’s road to $71.2 million was not smooth. In 2013, Sotheby’s sold it for an even higher $83 million, but the winning bidder never paid, and the sale collapsed. Sotheby’s ended up buying the diamond itself just to keep the deal alive, then resold it in Hong Kong in 2017 to Chow Tai Fook, a major jewelry retailer, which renamed it the CTF Pink Star. Pink diamonds this size are rare for a simple reason: scientists believe pink color comes from distortions inside a diamond’s crystal structure formed under intense pressure, not from a chemical impurity like the boron that colors blue diamonds, which makes the right conditions even harder to find in nature.
What Is the Most Expensive Finished Piece of Jewelry Ever Sold?
The Pink Star was a loose diamond, not a finished piece someone could wear. Among jewelry that was actually mounted and wearable, the record belongs to a pearl and diamond pendant once owned by Marie Antoinette, which sold for $36.2 million in 2018.
The pendant holds a single natural pearl shaped like a drop, hanging beneath a diamond bow. Marie Antoinette’s family reportedly smuggled it out of France during the French Revolution in 1791, and it stayed in the hands of European royalty, the Bourbon-Parma family, for more than two hundred years before it ever went up for public sale. Sotheby’s had estimated it would sell for around $2 million. It sold for eighteen times that.
Natural pearls this large and this well formed are almost impossible to find today, since the wild oyster beds that once produced them have been fished out for generations. Every pearl sold now is checked with X-ray imaging to prove it grew naturally rather than being cultured on a farm, because cultured pearls, grown by inserting a bead into an oyster, are common and worth far less. A natural pearl this size, confirmed authentic and tied to one of history’s most famous queens, is simply not something a jeweler can go out and find again.
A beautiful jewel is one thing. A jewel with two hundred years of royal history behind it is something else entirely, and buyers pay for both.
What Is the Most Expensive Necklace in the World?
The most expensive necklace ever created is “A Heritage in Bloom,” a diamond and jade necklace valued at $200 million. It has never been sold, so this number comes from the jeweler’s own valuation rather than an auction result, but it still holds the title of the most valuable necklace ever made.
Hong Kong jewelry artist Wallace Chan designed the piece for the retailer Chow Tai Fook, unveiling it in 2015. It contains 11,551 diamonds and took his workshop more than 47,000 hours to complete, roughly the equivalent of one person working full time for 22 years. Its centerpiece is a 104-carat diamond cut from the Cullinan Heritage, a 507.55-carat rough diamond that Chow Tai Fook had bought on its own in 2010 for around $35 million — meaning the price of that single rough stone, before Chan ever began setting a single diamond, already rivaled what most finished jewelry sells for at auction.
The design is built to come apart and reassemble into 27 different looks, so the same necklace can become a shorter choker, a brooch, or several smaller pieces depending on the occasion. Chan is also a materials inventor rather than only a designer: he created the “Wallace Cut,” a technique for carving a reflected 3D image inside a gemstone, and later spent seven years developing a porcelain five times stronger than steel, which is part of why his work commands prices that most jewelers never reach.
What Is the Most Expensive Ruby Ever Sold?
The record for a colored gemstone other than a diamond belongs to the Estrela de Fura, a 55.22-carat Mozambican ruby that sold for $34.8 million in 2023. It is also the largest gem-quality ruby ever to reach auction, cut from a 101-carat rough stone that was itself a rare find.
Miners at the Fura Gems mine in Montepuez, Mozambique, unearthed the rough stone in July 2022. A team of specialists spent months studying it before cutting it into a 55.22-carat cushion shape, and Sotheby’s mounted the finished stone in a yellow gold ring and sold it in New York in June 2023 for $630,288 per carat, a record for any ruby or any colored gemstone at auction. Rubies from Mozambique’s deposits are newer to the market than the Burmese stones that once dominated it, and this sale showed collectors that African rubies could match, and beat, the prices Burmese stones had commanded for decades.
Before the Estrela de Fura, the record belonged to the Sunrise Ruby, a 25.59-carat Burmese ring that sold for $30.3 million in 2015. The stone has what gem experts call “pigeon’s blood” red, the deepest and most prized shade a ruby can have, and Cartier set it between two white diamonds shaped like shields. Its name comes from a poem of the same name by the 13th-century Sufi poet Rumi, which describes a ruby held up to the sunrise until the stone and the light become impossible to tell apart. Rubies and diamonds form under very different geological conditions, and the specific mix of heat, pressure, and chromium needed to create a fine ruby happens far less often than the conditions that create diamonds, which is why both of these stones sold for so much more than their size alone would suggest.
What Are the Most Expensive Sapphire and Emerald Ever Sold?
The record for a sapphire belongs to the Blue Belle of Asia, a 392.52-carat stone that sold for $17.3 million in 2014. The record for an emerald belongs to the Aga Khan Emerald, a 37-carat stone that sold for $8.9 million in 2024, though a smaller, more famous emerald still holds a different record of its own.
The Blue Belle of Asia is a Ceylon sapphire, meaning it was mined in Sri Lanka, and it remains untreated, which is rare at this size since most large sapphires are heated to improve their color. Christie’s sold it in Geneva in 2014, and its size alone makes it one of the largest faceted blue sapphires ever offered at auction. Sapphires and rubies are technically the same mineral, corundum, and only differ in the trace elements that color them, which is why a fine sapphire can rival a ruby in both rarity and price.
Emeralds work a little differently than diamonds, rubies, or sapphires, because almost every emerald on the market has been treated with oil to hide small internal cracks and improve its color. That makes untreated stones far more valuable, and it explains why two different emeralds hold two different records today. The Aga Khan Emerald, a 37-carat brooch once owned by socialite Nina Dyer, sold for $8.9 million at Christie’s Geneva in 2024, making it the most expensive emerald ever sold overall. The 18.04-carat Rockefeller Emerald, sold for $5.5 million in 2017, still holds the record for the highest price paid per carat, since its smaller size means every carat of it sold for more money than any other emerald in history. A stone’s total price and its price per carat are simply different measurements, and the biggest number in each category does not always belong to the same gem.
What Is the Most Expensive Blue Diamond Ever Sold?
The Oppenheimer Blue holds the record for a blue diamond, selling for about $57.5 million in 2016. At the time, it was the highest price ever paid for any jewel at auction, a record it held until the Pink Star sold the following year.
The diamond weighs 14.62 carats and is graded “Fancy Vivid Blue,” the top color grade a diamond can receive. It gets its name from Sir Philip Oppenheimer, a former executive at the diamond company De Beers who once owned it, and Verdura mounted it in a platinum ring flanked by two smaller diamonds. Two bidders fought over the ring by phone for 25 minutes before the hammer finally came down, well above its pre-sale estimate of $38 million.
Blue diamonds get their color from tiny traces of boron trapped inside the crystal as it formed hundreds of miles underground, and only a small fraction of one percent of all diamonds mined are true fancy-color blue. The Oppenheimer Blue briefly took the crown from an earlier record holder, the Blue Moon of Josephine, which had sold for $48.4 million just months before, showing how quickly a record can fall when two collectors want the same rare color.
What Is the Most Expensive Jadeite Necklace?
Jadeite, the most prized type of jade, set its own auction record with the Hutton-Mdivani Necklace, which sold for $27.4 million in 2014. It remains the most expensive piece of jade jewelry ever sold.
Cartier assembled the necklace in the early 1930s from 27 jadeite beads, ranging from about 15 to 19 millimeters wide, all cut from the same boulder and matched so closely in color and translucency that experts still consider it unrepeatable. American heiress Barbara Hutton, granddaughter of the Woolworth retail fortune, received the necklace from her father as a wedding gift in 1933 when she married Prince Alexis Mdivani, and Cartier later redesigned its clasp in gold, rubies, and diamonds at her request.
Jadeite of this quality was historically prized in Imperial China, where the Qing dynasty’s Empress Dowager Cixi was famous for her own jade collection, and the color standard collectors still use today, called “imperial jade,” traces back to that era. The necklace shows just how much jadeite has appreciated: it first sold at auction in 1988 for $2 million, already a record at the time, before selling again in 2014 for more than thirteen times that price.
Are the Hope Diamond and the Crown Jewels the Most Expensive of All?
Not exactly, because they are not for sale, and that changes the math. The Hope Diamond is insured for somewhere between $200 million and $350 million, and pieces like the Cullinan I diamond in the British Crown Jewels are considered priceless because no owner has ever offered them for auction.
The Hope Diamond is a 45.52-carat deep blue diamond that has lived at the Smithsonian Institution in Washington, D.C. since 1958, when jeweler Harry Winston donated it. Before that, it was cut down from a much larger rough stone bought in India by the French merchant Jean-Baptiste Tavernier in the 1660s, later owned by King Louis XIV of France as “the Blue of France,” and reportedly stolen during the French Revolution before resurfacing decades later in a different cut. Because it will likely never be sold again, its “value” is really just an insurance estimate, a number used to protect it rather than a price anyone actually paid.
The same logic applies to the Crown Jewels of the United Kingdom. The 530-carat Cullinan I, also called the Great Star of Africa, was cut from a 3,106-carat rough diamond found at a mine near Pretoria, South Africa, in 1905, the largest gem-quality rough diamond ever discovered, and it now sits in the head of the Sovereign’s Sceptre. Its sister stone, the 317-carat Cullinan II, sits in the Imperial State Crown. Both belong to the British monarchy rather than a private collector, and the origins of famous royal diamonds like these, mined during the colonial era in Africa and Asia, are still debated today by historians and by the countries where they were originally found. National treasures like this simply never enter the open market, which is exactly why “priceless” and “most expensive” are not always the same thing.
Why Do Some Jewelry Pieces Cost So Much?
Four things drive the price of a jewel into the tens or hundreds of millions: rarity, color, size, and history. A piece usually needs at least two of these working together to reach record-breaking numbers.
Rarity means how often a gem of that type, size, and quality shows up at all. Fancy vivid pink and blue diamonds, for example, make up a tiny sliver of all diamonds ever mined, so even a small one can be worth more than a much bigger colorless diamond. Size matters too, but only alongside quality; a huge stone with visible flaws is worth far less than people expect, and a jeweler will always choose a smaller, cleaner stone over a larger, cloudy one.
History, or what jewelers call provenance, can multiply a price many times over. A gem once owned by a queen, a famous jeweler, or a historic family carries a story that a brand-new stone simply cannot match, which is exactly why Marie Antoinette’s pendant sold for eighteen times its estimate and why the Hutton-Mdivani necklace sold for more than thirteen times its own 1988 price once it changed hands again in 2014.

Frequently Asked Questions
What is the single most expensive piece of jewelry ever sold?
The Pink Star diamond holds the record at $71.2 million, sold at Sotheby’s in Hong Kong in 2017. Among finished jewelry that can actually be worn, the record belongs to Marie Antoinette’s pearl and diamond pendant, which sold for $36.2 million in 2018.
Why are colored diamonds worth more than clear diamonds?
Colored diamonds, especially vivid pink, blue, and red, are far rarer than ordinary white diamonds. Only a tiny fraction of all diamonds ever found have strong, even color, so buyers pay a steep premium for that scarcity.
Is the Hope Diamond for sale?
No. The Hope Diamond belongs to the Smithsonian Institution and has not been sold since 1958. It is insured for an estimated $200 to $350 million, but that figure reflects risk protection, not a market price.
Why does provenance make jewelry more expensive?
Provenance is the documented history of who owned a piece before. Jewelry connected to royalty, celebrities, or major historical events often sells for many times its pre-sale estimate, because buyers are paying for the story as much as the gemstone.
What makes jadeite jewelry so valuable?
High-quality jadeite needs an intense, even green color called imperial jade, and stones of that quality are difficult to find even one at a time. Necklaces made from many matching jadeite beads, like the Hutton-Mdivani Necklace, are especially rare because every bead has to match, and prices for the finest pieces have kept climbing for decades.
The Bottom Line
The prices behind the world’s most expensive jewelry rarely come down to size alone. A diamond needs rare color, a ruby needs the deepest possible red, and a pearl or a necklace often needs a history that stretches back centuries before collectors will pay tens of millions for it. What ties these record-breaking sales together is scarcity: each piece is, in some specific way, the only one of its kind, and that is a quality no amount of money can manufacture from scratch.
