The most expensive jewelry in the world includes pieces valued from $11 million to an estimated $350 million for a single stone. The Hope Diamond, valued at approximately $350 million, is the highest-valued single jewelry piece on Earth. At auction, pink and blue diamonds have broken records repeatedly, with the Pink Star selling for $71.2 million in 2017. This guide covers the top 10 most expensive pieces by price, the brands behind extreme luxury, and the gemstones that drive these numbers.
What Makes Jewelry Reach Record-Breaking Prices
Four factors push jewelry into eight and nine-figure territory:
-
Gemstone rarity: natural colored diamonds (blue, pink, red) carry the highest price-per-carat of any material on Earth
-
Carat weight: larger stones with no inclusions scale exponentially in value, not proportionally
-
Historical provenance: documented royal or celebrity ownership adds verifiable market premium
-
Brand craftsmanship: houses like Graff, Cartier, and Harry Winston add substantial value through precision setting and design history
The 4Cs of diamond quality (color, cut, clarity, and carat) form the standard framework for how every stone on this list is graded and priced.
Top 10 Most Expensive Jewelry Pieces in the World
1. The Hope Diamond: Estimated $350 Million
The Hope Diamond is the most expensive piece of jewelry in the world by estimated value. It is a 45.52-carat fancy deep blue diamond on display at the Smithsonian National Museum of Natural History in Washington, D.C.
Its rare blue color is caused by trace amounts of boron inside the crystal structure. It has never been offered at public auction, which makes its $350 million estimate based on comparable blue diamond transactions at that size and color grade.
2. Pink Star Diamond: $71.2 Million
The Pink Star is the world's most expensive jewelry piece ever sold at auction. It is a 59.60-carat fancy vivid pink diamond sold at Sotheby's Hong Kong in April 2017.
CTF Jewelry, a subsidiary of Chow Tai Fook, purchased it and renamed it the CTF Pink Star. Pink diamonds at this carat weight and color saturation are among the scarcest gemstones ever documented.
3. Oppenheimer Blue Diamond: $57.5 Million
A 14.62-carat fancy vivid blue diamond ring sold at Christie's Geneva in May 2016. At the time of sale, it set a world record for any diamond at auction.
Blue diamond jewelry at any scale starts with understanding why color grade alone can separate two diamonds of similar size by tens of millions in market value.
4. Blue Moon of Josephine: $48.5 Million
A 12.03-carat fancy vivid blue diamond sold at Sotheby's Geneva in November 2015. Hong Kong billionaire Joseph Lau purchased it as a gift for his daughter and named it the Blue Moon of Josephine.
Per-carat, it set a world record for any gemstone at the time of its sale.
5. Graff Pink Diamond: $46.2 Million
A 24.78-carat fancy intense pink diamond purchased by Laurence Graff at Sotheby's Geneva in 2010. It broke the world auction record for any jewel at the time of sale.
Graff later mounted it in a ring setting, and it now sits in the Graff private collection.
6. Sunrise Ruby by Cartier: $30.3 Million
The Sunrise Ruby is the world's most expensive ruby and the world's most expensive colored gemstone other than diamond. It is a 25.59-carat Burmese ruby ring by Cartier, sold at Sotheby's Geneva in May 2015.
Its "pigeon's blood" red color and confirmed Burmese origin are the rarest combination in the ruby market globally.
7. Wittelsbach-Graff Diamond: $24.3 Million
A 31.06-carat fancy deep blue diamond with confirmed European royal provenance. Sold at Christie's London in December 2008 for $24.3 million, it was purchased by Laurence Graff. He later had it recut to improve brilliance, reducing it slightly from its original weight.
8. Winston Blue Diamond: $23.8 Million
A 13.22-carat fancy vivid blue diamond ring sold at Christie's Geneva in May 2014. Harry Winston, who named and acquired it, has built one of the highest-profile portfolios in luxury diamond history.
Collectors who monitor diamond jewelry as a long-term investment often use Harry Winston's auction results as a performance benchmark.
9. The Perfect Pink Diamond: $23.2 Million
A 14.23-carat fancy vivid pink diamond ring sold at Christie's Hong Kong in 2010. The auction house named it based on its near-flawless clarity grade and exceptional color saturation across the full stone.
10. La Peregrina Pearl Necklace: $11.8 Million
One of the world's most historically documented pearls, with provenance tracing back to Queen Mary I of England in the 16th century. Elizabeth Taylor had it set into a Cartier pearl and diamond necklace.
Christie's New York sold it in December 2011 for $11.8 million, nine times its pre-sale estimate.
Most Expensive Jewelry Brands in the World
The world's most expensive jewelry brands compete on two things: access to the rarest stones and the precision of their setting work.
-
Graff: London-based, founded 1960. Known for sourcing and cutting the rarest diamonds globally, including several auction record holders
-
Harry Winston: New York-based, known as the "King of Diamonds." His house holds decades of record-setting auction results
-
Cartier: Paris-based, founded 1847. Known for royal commissions and iconic collections, including the Panthère and the setting of the Sunrise Ruby
-
Van Cleef and Arpels: French house known for the Mystery Set technique, which hides all metal beneath a surface of precisely fitted stones
-
Bulgari: Italian house known for bold colored gemstone combinations and layered Roman design
-
Tiffany and Co.: American house best known for the Tiffany Yellow Diamond (128.54 carats) and its engagement ring legacy
-
Chopard: Swiss house known for the Happy Diamonds collection and large-scale high jewelry event pieces
By per-piece auction price, Graff is widely considered the most expensive jewelry brand in the world.
Most Expensive Gemstones in Jewelry
Gemstone type sets the price ceiling for any piece:
-
Red diamonds: fewer than 30 genuine red diamonds are known to exist. The rarest diamond color by documented global supply
-
Blue diamonds: Type IIb stones with trace boron. The Oppenheimer Blue and Blue Moon represent the benchmark for this category
-
Pink diamonds: primarily from the Argyle Mine in Western Australia, which closed permanently in 2020. Existing supply will not be replenished
-
Burmese rubies: "pigeon's blood" color grade reaches $1 million or more per carat at the top quality level
-
Kashmir sapphires: from a region of India that stopped commercial production in the early 1900s. Documented Kashmir origin adds a verified premium above other sapphire sources
-
Colombian emeralds: Muzo-origin stones with high clarity reach $100,000 or more per carat
Buyers who want the visual brilliance of high-grade diamonds without auction-level pricing often choose VVS moissanite jewelry, which delivers near-identical light performance. For a full comparison of how both stones perform, the moissanite vs. diamond breakdown covers the key differences in clarity, hardness, and price.
Who Owns the Most Expensive Jewelry Collections in the World
The largest verified collections at this level are held by:
-
The British Royal Family: The Crown Jewels include the Cullinan I (530.2 carats, the world's largest colorless cut diamond) and the Koh-i-Noor (105.6 carats). No public sale value has ever been set, but the collection is estimated in the billions
-
Laurence Graff: Personal purchaser of the Graff Pink, the Wittelsbach-Graff Diamond, and several other record-breaking stones. His holdings represent the highest concentration of documented high-value diamond transactions by a single collector
-
Joseph Lau: Hong Kong businessman who purchased both the Blue Moon of Josephine and the Sweet Josephine Pink Diamond for his daughter at the same Sotheby's auction in 2015
-
Elizabeth Taylor (estate): Her personal jewelry collection sold at Christie's New York in December 2011 for over $150 million total. At the time, it was the highest amount ever realized for a private jewelry collection at public auction
Rappers, athletes, and entertainers also hold collections at the high-value level. A closer look at celebrity jewelry ownership and luxury taste covers how cultural wealth translates into diamond and gemstone choices.
Conclusion
These ten pieces share one defining fact: supply will never recover. The Argyle Mine closed permanently in 2020, ending the primary global source of pink diamonds. Kashmir sapphire and high-grade Burmese ruby deposits have been commercially exhausted for decades. The Hope Diamond shows no indication of entering the public market. As documented supply contracts, the floor on rare stone pricing has one consistent historical direction. Buyers exploring the visual scale of high-clarity jewelry at accessible price points can browse the full range at Glazed Diamonds, including moissanite engagement rings built to VVS visual standards.
