141:

The Crown Jewels of the United Kingdom are 141 historic ceremonial objects, including the regalia and vestments worn by kings and queens of the country at their coronations, as well as processional and anointing objects, plate, and christening fonts.

A symbol of 800 years of monarchy, the sovereign's coronation regalia is the only working collection in Europe – other present-day monarchies have abandoned coronations in favour of inauguration or enthronement ceremonies – and is the largest set of regalia in the world. Objects used to invest and crown the monarch variously denote his or her roles as Head of State, Supreme Governor of the Church of England, and Commander-in-Chief of the British Armed Forces. Wives of kings are crowned as queen consort with a plainer set of regalia. Since 1831, a new crown has been made specially for each queen consort.

The use of regalia by monarchs in Britain can be traced back to its early history. Most of the present collection as a whole dates from around 350 years ago when King Charles II ascended the throne. The medieval coronation regalia and Tudor state regalia had been either sold or melted down by Oliver Cromwell, a republican who overthrew the monarchy in 1649, during the English Civil War. Notable among the precious stones which adorn the regalia are Cullinan I (the largest clear cut diamond in the world), Cullinan II (second-largest of the Cullinan diamonds), the Koh-i-Noor diamond with a history going back to the 13th century, the Stuart Sapphire, St Edward's Sapphire, and the Black Prince's Ruby – a large spinel worn by King Henry V at the Battle of Agincourt.
