The most expensive jewelry in the world ranges from the Hope Diamond, estimated at $250 million, to auction-sold pieces like the Pink Star Diamond at $71.2 million. These prices reflect rarity, color grade, provenance, and craftsmanship — not just size.
Quick Answer: Top 10 Most Expensive Jewelry Pieces
Before going into the detail, here is a clear reference table. Note that some prices are confirmed auction results, while others are estimates or private sale figures — these are not directly comparable without context.

Auction Price vs. Estimated Value — Why the Difference Matters
This is something all three major articles on this topic get wrong by omission. They list auction results and estimated valuations side by side as if they are the same thing. They are not.
An auction price is a real, documented transaction. A buyer paid that exact amount on a specific date. It is verifiable.
An estimated value — like the Hope Diamond's $250 million — is an approximation based on insurance assessments, comparable sales, and expert opinion. The Hope Diamond has never been sold in modern times. Its $250 million figure is widely reported but is not a transaction price.
In practice, insurers and gemological institutions use a combination of comparable auction data, provenance weight, and rarity modeling to arrive at these figures — and different assessors often produce different numbers.
What's often overlooked is that a private sale price, like the Wittelsbach-Graff's reported $80 million in 2011, sits somewhere in between. It is a real transaction but not publicly verified in the way an auction record is.
When comparing these pieces, the basis of the price matters as much as the number itself.
What Drives the Price of the Most Expensive Jewelry
Gemstone Color and Rarity Grade
Color is, arguably, the single biggest price driver for most expensive diamonds in the world — and for colored gemstones generally. White diamonds get graded on a D-to-Z scale, where D is colorless. Colored diamonds work differently. A pink or blue diamond with intense, natural color gets graded as "fancy," and the highest level of that grading is "fancy vivid."
Fancy vivid pink and blue diamonds are extraordinarily rare. Statistically, for every million carats of diamonds mined, fewer than one carat will be a naturally colored fancy vivid stone. That scarcity is what makes the Pink Star or the Oppenheimer Blue so far removed in price from a colorless diamond of similar size.

Carat Weight — Bigger Is Not Simply More Expensive
Weight matters, but not linearly. A 10-carat fancy vivid blue diamond does not cost twice as much as a 5-carat one of the same grade. It can cost five to ten times as much, because large stones of high color quality become exponentially rarer as size increases.
Provenance — The History Behind the Stone
A diamond once owned by European royalty, or one with a documented 300-year lineage, commands a premium that has nothing to do with its physical properties. Marie Antoinette's pearl pendant sold at Sotheby's for $36.2 million in 2018. The pearl itself, on purely gemological grounds, would not justify that price. The history did.
Craftsmanship and Designer Legacy
Who cut it, who set it, and who designed the piece all contribute to final value. The Hutton-Mdivani Jadeite Necklace was purchased at auction by Cartier — the same house that originally designed it. That is not a coincidence. Pieces with clear maker identity and design integrity hold value differently from anonymous stones of equivalent quality.
Certification and Cut Quality
"Fancy vivid" is a grade issued by the Gemological Institute of America (GIA). Without that certification, a pink diamond cannot command the same price regardless of how it looks to the eye. In practice, gem dealers and auction houses treat GIA grading as the floor requirement for serious bidding on rare gemstones value at this level.
The World's Most Expensive Jewelry — Detailed Profiles
1. Hope Diamond — ~$250 Million (Estimated)
Weighing 45.52 carats, the Hope Diamond is the most recognizable blue diamond in existence. Its deep blue color comes from trace amounts of boron in its crystal structure — a geological accident that makes it visually unlike almost any other stone on record.
Its history is long and reasonably well-documented back to 17th-century France. Past owners include King Louis XIV, who had it recut, and American socialite Evalyn Walsh McLean. Harry Winston acquired it in 1949 and donated it to the Smithsonian Institution, where it has remained since.
The "curse" attached to it — linking owners to misfortune — is largely legend. Some documented owners did experience tragedy, but the pattern is inconsistent and has been selectively emphasized over time.
As documented by Wikipedia, the $250 million figure reflects its insurance valuation — the stone was described by a Smithsonian curator as "priceless" and "irreplaceable," and is reported to be insured at that amount. It is not a transaction price. The stone has not been sold or publicly auctioned in the modern era.
It resides permanently at the Smithsonian National Museum of Natural History in Washington, D.C., where it is viewable by the public.
2. Peacock Brooch by Graff Diamonds — ~$100 Million (Estimated)
Created by Graff Diamonds founder Laurence Graff, the Peacock Brooch contains 1,305 stones totaling 120.81 carats. The centerpiece is a pear-shaped dark blue diamond of approximately 20 carats. The $100 million figure is an estimated valuation, not an auction price. The piece has not been publicly sold.
What makes it notable beyond the materials is the construction — assembling over a thousand stones into a coherent design without visual clutter is a significant technical achievement in high jewelry.
3. Wittelsbach-Graff Diamond — ~$80 Million
This blue diamond's history goes back to the 1600s, when it was part of the Habsburg Crown Jewels. It passed to the Wittelsbach family of Bavaria in 1722 and remained in private hands for centuries before being auctioned in 2008 for $24.3 million.
The buyer was Laurence Graff, who made the decision to have the stone recut — reducing it from 35.56 carats to 31.06 carats to improve its color and clarity grade. This was controversial.
Gemologists criticized the decision as an irreversible alteration of a historically intact stone. Graff's position was that the recut revealed the stone's full optical potential. Both views have merit, and the debate in gemological circles has not fully settled.
The renamed Wittelsbach-Graff Diamond was later sold for approximately $80 million to a member of the Qatari royal family in 2011.
4. Pink Star Diamond — $71.2 Million (Auction, 2017)
Mined by De Beers in South Africa in 1999 as a 132.5-carat rough stone, the Pink Star was cut over 20 months by eight diamantaires at Steinmetz Diamonds. The result was a 59.60-carat fancy vivid pink diamond with flawless clarity — a combination almost without precedent at that size.
What is often left out of coverage: the Pink Star was first auctioned at Sotheby's in 2013, where it sold for $83 million. That sale was cancelled when the buyer, Isaac Wolf, defaulted on the payment. Sotheby's subsequently purchased the stone itself and brought it back to auction in 2017 in Hong Kong.
As reported by The Washington Post, the Pink Star sold for $71.2 million to Dr. Henry Cheng Kar-Shun of Chow Tai Fook Enterprises — making it the most expensive jewelry sold at auction of all time. The 2017 figure is the confirmed, completed transaction. The 2013 number is not.
5. Oppenheimer Blue — $57.5 Million (Auction, 2016)
A 14.62-carat fancy vivid blue diamond set in a platinum ring with trapeze-shaped side diamonds, the Oppenheimer Blue was commissioned by De Beers chairman Philip Oppenheimer for his wife. Its full mining and early ownership history is not publicly documented. What is known is that it was mined in South Africa, likely in the early 20th century.
It sold at Christie's Geneva in 2016 for $57.5 million — at the time, the highest price ever achieved at auction for any jewel. The most expensive jewelry sold at auction record it held was subsequently broken by the Pink Star in 2017.
6. L'Incomparable Diamond Necklace — $55 Million (Estimated)
Created by Lebanese jeweler Mouawad, L'Incomparable features a 407.48-carat yellow diamond at its center — one of the largest diamonds ever cut — surrounded by 91 smaller clear diamonds set in 18-carat gold. The total piece is reported to be valued at $55 million, though this is an estimated figure, not an auction result.
The origin story — that the central diamond was discovered by a young girl in the Democratic Republic of Congo in the 1980s among a pile of rubble — is widely reported but has not been independently verified. It is plausible but should be read as reported, not confirmed.
7. Pink Legacy Diamond — $50.7 Million (Auction, 2018)
The Pink Legacy is an 18.96-carat fancy vivid pink diamond with a cut-cornered rectangular shape. It was mined in South Africa around 1918 and was once part of the Oppenheimer family collection — the same family connected to the Oppenheimer Blue. It was purchased at Christie's Geneva in 2018 by Harry Winston for $50.7 million and subsequently renamed.
8. Blue Moon of Josephine — $48.4 Million (Auction, 2015)
Discovered in South Africa in 2014, the Blue Moon of Josephine is a 12.03-carat fancy vivid blue diamond. It sold at Sotheby's Geneva in 2015 for $48.4 million — setting, at the time, the record for the highest expensive gemstone price per carat ever achieved at auction: approximately $4 million per carat.
It was purchased by Hong Kong businessman Joseph Lau Luen-Hung and named after his daughter, Josephine. One competitor article incorrectly attributes the name to Josephine Bonaparte. The stone is named after a living person, not the historical figure.
9. Estrela de Fura Ruby — $34.8 Million (Auction, 2023)
The Estrela de Fura is a 55.22-carat ruby from Mozambique, described by Sotheby's as the world's largest gem-quality ruby to appear at auction. "Pigeon-blood" red — the term used to describe its color — is the highest classification in ruby grading, referring to a pure, vivid red with a very slight blue undertone.
Rubies at this quality level rarely reach diamond-equivalent prices because large, inclusion-free rubies are almost never found. This stone was an exception. Its 2023 sale at $34.8 million at Sotheby's New York made it the most expensive colored non-diamond gemstone sold at auction.
10. Hutton-Mdivani Jadeite Necklace — $27.4 Million (Auction, 1994)
Commissioned by American businessman Franklyn Laws Hutton as a wedding gift for his daughter Barbara Hutton in 1933, this Cartier-designed necklace is made of 27 jadeite beads with a ruby, gold, and diamond clasp.
Jadeite is the rarer of the two minerals commonly called "jade." High-quality jadeite typically cannot yield beads larger than 10 millimeters in diameter. Every bead on this necklace exceeds 15 millimeters — all cut from the same boulder, which is what makes it structurally remarkable. It sold at auction in 1994 for $27.4 million. The buyer was Cartier, the piece's original designer.
Honorable Mention — Chopard 201-Carat Watch: $25 Million
The Chopard 201-Carat Watch is included here because the line between high jewelry and a luxury timepiece is not always clear. This piece contains a 15-carat heart-shaped pink diamond, a 12-carat blue diamond, and an 11-carat yellow diamond, alongside hundreds of smaller stones. At $25 million, it functions as both a wearable watch and a jewelry piece in the traditional sense.
Price Per Carat — A More Useful Comparison
Total price can mislead. A large stone sold cheaply per carat can headline a bigger number than a smaller stone sold at record per-carat rates. Price per carat normalizes the comparison.

The Blue Moon of Josephine, despite not holding the top total price, holds the record for the highest confirmed price per carat at auction. Interestingly, the Pink Star's total price is nearly 50% higher, but its per-carat figure is a fraction of the Blue Moon's — because it is nearly five times larger.
This matters for collectors and investors. A smaller stone of extreme color quality can be a more concentrated store of value than a larger stone of only slightly lesser grade.
Where Can You See These Pieces Today?
Most of these pieces are privately held, and their current locations are not publicly disclosed. The one clear exception is the Hope Diamond, which has been on permanent display at the Smithsonian National Museum of Natural History in Washington, D.C. since 1958. It is freely viewable as part of the museum's geology collection.
The Wittelsbach-Graff Diamond is believed to be in the collection of a member of the Qatari royal family, though this has not been formally confirmed. The remaining pieces on this list — including the Pink Star, Oppenheimer Blue, and Blue Moon of Josephine — are in private hands with no public display access reported.
Conclusion
The most expensive jewelry in the world gets its value from a combination of color rarity, provenance, carat weight, and craftsmanship — rarely from any single factor alone. Auction prices and estimated valuations are not the same thing, and that distinction matters when comparing these pieces fairly.
Frequently Asked Questions
What is the most expensive piece of jewelry ever sold at auction?
The Pink Star Diamond holds this record — sold at Sotheby's Hong Kong in 2017 for $71.2 million. A 2013 auction of the same stone at $83 million was cancelled after the buyer defaulted.
Why are pink and blue diamonds so much more expensive than white diamonds?
Natural pink and blue diamonds are statistically rare — fewer than one carat in a million qualifies as fancy vivid. That scarcity, combined with strong collector demand, drives prices far above colorless diamonds of equivalent size.
What does "fancy vivid" mean in diamond grading?
It is the highest color grade issued by the GIA for colored diamonds, indicating the most intense and evenly distributed color saturation. Only a small fraction of colored diamonds reach this grade.
How is the Hope Diamond valued at $250 million if it has never been sold?
The figure is an insurance and expert estimate based on comparable auction data, rarity, and provenance — not a transaction price. Different assessors may produce different numbers. It is a reference figure, not a confirmed sale value.
What is the most expensive non-diamond jewelry ever sold?
The Estrela de Fura Ruby, sold at Sotheby's New York in 2023 for $34.8 million, is the most expensive colored non-diamond gemstone sold at auction on record.
