The strongest candidates for the most significant pieces include the Cullinan diamonds, the Nizam of Hyderabad necklace and the Delhi Durbar necklace—but their monetary values cannot be confirmed from the available official records. It also matters whether a jewel was Elizabeth II’s personal property or part of the Crown Jewels, which she held as sovereign rather than as private jewelry.
Why there is no definitive answer about the most expensive piece
“Most expensive” implies a comparable monetary valuation. The Royal Collection Trust’s published accounts describe provenance, materials, design and use; they do not provide appraisals or a price list ranking the Queen’s jewels. That means a specific figure—or a claim that one jewel was definitively the most expensive—would be speculation unless attributed to a separate, named valuation. The gem weights and counts below are documented specifications, not price estimates.

Another complication is ownership. Some jewels associated with Elizabeth II were personal jewelry, while others were regalia belonging to the Crown. The distinction changes what “in her collection” means and prevents treating every famous royal jewel as privately owned by the late Queen.
Personal jewelry versus the Crown Jewels
The Crown Jewels are ceremonial regalia held by the monarch in trust for the nation, not a private jewelry collection. The Royal Collection Trust calls them “the most complete collection of royal regalia in the world.” Royal Collection Trust: The Crown Jewels

The Cullinan stones illustrate the distinction. Cullinan I is mounted in the Sovereign’s Sceptre and Cullinan II in the Imperial State Crown. The Trust says that Cullinan III–IX form part of Elizabeth II’s personal jewelry. Royal Collection Trust: The Cullinan Diamond
The Cullinan diamonds: extraordinary size, but no public price ranking
The Cullinan rough diamond was discovered in what is now South Africa in 1905 and weighed 3,106 carats. According to the Royal Collection Trust, three polishers spent eight months cutting it, producing nine large stones and 97 small brilliants. The two largest became part of the Crown Jewels; stones III–IX became personal jewelry associated with Elizabeth II. Royal Collection Trust: The Crown Jewels: Coronation Regalia
The famous name and exceptional scale make the Cullinan stones natural contenders in any discussion of the Queen’s most valuable jewels. But the published figures establish their size and history, not their monetary value. Nor should the value of the Crown Jewels’ Cullinan I and II be presented as the value of Elizabeth II’s personal jewelry.

Other notable jewels in Elizabeth II’s personal collection
The Royal Collection Trust’s 2022 account of jewels displayed at Buckingham Palace documents several pieces with notable histories and gem details. Those facts help explain their significance, but do not establish which would command the highest price.
Nizam of Hyderabad necklace
The Nizam left instructions with Cartier in London for Princess Elizabeth to choose a wedding gift. She selected a platinum necklace set with approximately 300 diamonds, according to the Royal Collection Trust’s 2022 release. Royal Collection Trust, 21 July 2022
Delhi Durbar necklace
Made for Queen Mary for the 1911 Delhi Durbar suite, this necklace incorporates nine emeralds that had belonged to Queen Mary’s grandmother, the Duchess of Cambridge, and an 8.8-carat diamond pendant cut from the Cullinan. Elizabeth II inherited it in 1953, the Trust reports. The documented carat weight belongs to the pendant diamond; it is not an appraisal of the necklace.
Rank #3
- Historical novel about the life of Queen Elizabeth I who was known as a very private person.
Vladimir Tiara
Made for Grand Duchess Vladimir around 1874, the tiara was bought by Queen Mary in 1921 and inherited by Elizabeth II in 1953. Its design allows it to be worn with pendant emeralds or pearls, according to the Trust’s 2022 account.
Girls of Great Britain and Ireland Tiara
Queen Mary gave the tiara to Princess Elizabeth as a wedding present in November 1947. It had first been presented to Queen Mary on her marriage in 1893.

South Africa necklace
The Government and Union of South Africa gave the necklace to Princess Elizabeth for her 21st birthday. It originally contained 21 brilliant-cut diamonds; six were removed in 1952 and made into a matching bracelet.
Rank #4
Sapphire and diamond Cartier bracelet
King George VI gave the bracelet to Princess Elizabeth for her 18th birthday in 1944.
The histories and specifications in these accounts come from the Royal Collection Trust’s 2022 release about the Buckingham Palace display. They provide useful context for comparing craftsmanship, provenance and use, but no monetary ranking.

The Diamond Diadem was created for George IV’s coronation in 1821 and is set with 1,333 brilliant-cut diamonds. Elizabeth II wore it on her coronation day and while travelling to and from the State Opening of Parliament, according to the Royal Collection Trust’s 2022 release. It is a coronet and regalia object, not simply a privately owned tiara. Its ceremonial role and public history make it important, but do not supply a sale price or appraisal.
Best Value
What can be said about value
The available official records support a comparison of documented features, not a ranking by price. The Cullinan stones stand out for scale and the story of their cutting; the Nizam necklace for its diamond setting and wedding-gift history; and the Delhi Durbar necklace for its emeralds and Cullinan-derived pendant. Regalia such as the Diamond Diadem and the Cullinan stones mounted in the Crown Jewels belong in a separate category from Elizabeth II’s personal jewelry.
Without published appraisals, a precise “most expensive” answer is not established. The careful conclusion is that these jewels are among the most historically and materially notable pieces associated with the late Queen, while their relative monetary values remain unverified.
