The Black Prince's Ruby is a large, irregular cabochon red spinel weighing {{convert|170|carat|g}} set in the cross pattée above the Cullinan II diamond at the front of the Imperial State Crown of the United Kingdom.{{Royal Collection|31701|The Imperial State Crown}}
The spinel is one of the oldest gems in the Crown Jewels of the United Kingdom, with a history dating back to the mid-14th century. According to a legend originating from the 1760s, the stone has been in the possession of the English and later British monarchy since it was given in 1367 by the Spanish king Peter of Castile to the then Prince of Wales, Edward of Woodstock, known as the "Black Prince".{{cite book|first=Sir Thomas|last=Butler|title=The Crown Jewels and Coronation Ceremony|url=https://books.google.com/books?id=brbvmKAQ5PEC|year=1989|publisher=Pitkin|isbn=978-0-85372-467-4|page=6}} Henry V is said to have worn it at the Battle of Agincourt in 1415{{Cite web |date=2021-08-16 |title=The Black Prince's Ruby |url=https://www.thecourtjeweller.com/2021/08/the-black-princes-ruby.html |access-date=2025-04-08 |website=The Court Jeweller |language=en-US}}.

Spinel
The Black Prince's Ruby weighs {{convert|170|carat|g}} and is approximately {{convert|4.3|cm|in|frac=4}} long.Ogden, p. 361. All red gemstones used to be referred to as rubies or "balas rubies". It was not until 1783 that spinels were chemically differentiated from rubies.{{cite web|url=http://www.gia.edu/UK-EN/spinel|title=Spinel|website=Gemological Institute of America|accessdate=16 December 2015}} Both contain aluminium and oxygen, and both derive their colour from chromium(III), but the spinel also contains magnesium, which rubies lack.
History
=Don Pedro of Seville=
According to tradition, the history of the Black Prince's Ruby dates back to the middle of the 14th century as the possession of Abū Sa'īd, the Arab Muslim Prince of the Emirate of Granada. At that time, the rule of Castile was being centralized to Seville and the Moorish Emirate of Granada was being systematically attacked and reverted to Castilian rule as a part of the Christian Reconquest of the Iberian Peninsula. Abū Sa'īd in particular was confronted by the belligerency of nascent Castile under the rule of Peter of Castile, also known to history as either Don Pedro the Cruel, or Don Pedro the Just. According to historical accounts, Abū Sa'īd wished to surrender to Don Pedro, but the conditions he offered were unclear. What is clear is that Don Pedro welcomed his coming to Seville. It is recorded that he greatly desired Abū Sa'īd's wealth. When Abū Sa'īd met with Don Pedro, the King had Abū Sa'īd's servants killed and may have personally stabbed Sa'īd to death himself. When Sa'īd's corpse was searched, the spinel was found and added to Don Pedro's possessions.{{cite web|title=Spinel History and Lore|url=https://www.gia.edu/spinel-history-lore|url-status=live|access-date=2021-05-18|website=Gemological Institute of America|language=en|archive-url=https://web.archive.org/web/20130802170713/http://www.gia.edu/spinel-history-lore|archive-date=2013-08-02}}
In 1366, Don Pedro's illegitimate brother, Henry of Trastámara, led a revolt against Don Pedro. Lacking the power to put down the revolt unaided, Don Pedro made an alliance with the Black Prince, the son of Edward III of England. The Black Prince took part in the Battle of Nájera, and apparently demanded the ruby in exchange for the services he had rendered. He later returned to England with King Pedro's two daughters, Dona Constanza of Castile and Dona Isabel of Castile, and marriages were contracted for them to the Prince's brothers. It is assumed that the Black Prince took the Ruby back to England at that time, although it disappears from historical records until 1415, when worn by Henry V of England.[https://www.rct.uk/collection/31701/the-imperial-state-crown Royal Collection Trust]{{cite web|title=Spinel History and Lore|url=https://www.gia.edu/spinel-history-lore|url-status=live|access-date=2021-05-18|website=Gemological Institute of America|language=en|archive-url=https://web.archive.org/web/20130802170713/http://www.gia.edu/spinel-history-lore|archive-date=2013-08-02}}
=A wartime adornment=
During his campaign in France, Henry V of England wore a gem-encrusted helmet that included the Black Prince's Ruby.{{cite book|title=The Jewelers' Circular| url=https://books.google.com/books?id=hhwcAQAAMAAJ|volume=99|year=1930|publisher=Jewelers' Circular Company|page=121}} In the Battle of Agincourt on 25 October 1415, the French Duke of Alençon struck Henry on the head with a battleaxe, and Henry nearly lost both the helmet and his life. The battle was won by Henry's forces and the Black Prince's Ruby was saved. Richard III is supposed to have worn the gemstone in his helmet at the Battle of Bosworth in 1485, in which he was killed.

Henry VIII's inventory of 1521 mentions "a great balas ruby" set in the Tudor Crown,{{cite book|url=https://archive.org/details/reportspapersofa17asso|chapter=King Henry VIII's Jewel Book|year=1521|first=John|last=Plowfeld|title=Associated Architectural Societies Reports and Papers|volume=17|page=[https://archive.org/details/reportspapersofa17asso/page/158 158]|editor=Edward Trollope|publisher=James Williamson}} thought to be the Black Prince's Ruby.{{cite book|first1=Jennifer|last1=Loach|author2=G.

Oliver Cromwell had the royal crowns disassembled and gems sold, and the gold was melted down and struck into coins. How the stone found its way back into the Royal Collection after the Interregnum is unclear, but a substantial "ruby" was acquired for the Crown Jewels in 1661 at a cost of £400, and this may well have been the spinel.Olivia Fryman in Bird and Clayton, "Ceremony and Coronation", p. 102. At the coronation of Queen Victoria in 1838, she was crowned with a new Imperial State Crown made for her by Rundell and Bridge, with 3,093 gems, including the spinel at the front. The Queen can be clearly seen wearing the jewel in the Imperial State Crown in her official coronation portrait by Sir George Hayter. This was remade in 1937 into the current, lighter, crown. A plaquette on the reverse of the gemstone commemorates the crown's history.
