Queen Elizabeth II had access to some of the world's most incredible jewels, many of which wore throughout her 70-year reign.
Without a doubt, the crowning glory of these pieces were her tiaras.
From her days as Princess Elizabeth to monarch of UK and the Commonwealth, the Queen truly had an iconic collection stepped in history - and sometimes even controversy.
As the world mourns Queen Elizabeth II, we look back at some of her tiaras and Crowns.

The Crown of Scotland was placed on top of the coffin of Queen Elizabeth II during a Service of Prayer and Reflection at St Giles' Cathedral, in Edinburgh on Monday, September 12, 2022.
The Crown is the first of four that will play a prominent ceremonial role in the funeral arrangements for the Queen and the Coronation of King Charles III.
The Crown of Scotland is the oldest of all the royal regalia and is worn by the monarch at the State Opening of the Scottish Parliament.
It pre-dates the Union (England, Northern Ireland, Wales and Scotland) and in its current form it was made in 1540 after King James V of Scotland ordered it to be refashioned from the previous crown, which was starting to fall apart.
The Crown is made of solid gold.
Its precious stones were removed and the Crown was melted down and an extra 1162 grams of Scottish gold were added, before the 22 gemstones and 68 pearls were mounted.
Originally lined with a purple bonnet, it has had a red bonnet since the days of James II (James VII of Scotland).
The Crown weighs 1.64kg and is kept in Edinburgh Castle as part of the Honours of Scotland.
Queen Mary's Diamond Fringe tiara was chosen by Princess Elizabeth to wear when she married Prince Philip on November 20, 1947.
And it was broken by her hairdresser just hours before the event, with the royal jewellers rushing to repair the priceless gem the morning of the wedding.
Since then, it has also become known as the Queen's Diamond Fringe tiara.
It was made by Garrard and features 47 diamond bars, along with smaller diamond spikes.
The stunning piece was crafted using diamonds from a necklace given to Queen Mary on her wedding day by her mother-in-law, Queen Victoria.
The tiara remains one of the Queen's personal favourites.
Most recently, the tiara was worn by the queen's granddaughter Princess Beatrice when she married when she married Edoardo Mapelli Mozzi on July 17, 2020.
Queen Elizabeth II was gifted the Halo tiara on her 18th birthday by Queen Elizabeth, the Queen Mother, but she's never worn it in public.
She received the headpiece in 1944, a year before the end of World War II, which may have influenced her decision not to wear the very expensive tiara.
The Queen, however, allowed her sister Princess Margaret to borrow the Halo tiara frequently, while Princess Anne also wore the tiara during the 1970s.
Its most famous public outing came on April 29, 2011, when it was worn by Kate Middleton on her wedding day to Prince William, the future King of England.
This tiara is believed to be the Queen's favourite diadem, which she wore frequently throughout her 70-year reign.
The tiara was a wedding present from the 'Girls of Great Britain and Ireland' to the Duchess of York, later Queen Mary, in 1893.
It was purchased with money raised by a committee chaired by Lady Eva Greville, who became one of Queen Mary's ladies-in-waiting.
The tiara came into Queen Elizabeth's possession in 1947, when Queen Mary gave it to her granddaughter as a wedding present.
Here, Her Majesty wears the tiara at a State Banquet for the Turkish president at Buckingham Palace in 2011.
Queen Elizabeth wore the tiara for the first official photographic sitting of the new sovereign on February 26, 1952, just 20 days after the accession.
Society photographer Dorothy Wilding took the portraits to use as the basis for the Queen's image on new coins, banknotes and stamps.
A total of 59 photos were taken, showing the queen wearing the Girls of Great Britain and Ireland tiara and the Diamond diadem and gowns by Norman Hartnell.
Queen Elizabeth wore the Girls of Great Britain and Ireland tiara to a banquet during her first official visit to Australia as monarch in 1954.
The original 1893 tiara featured 14 pearls on top, but Queen Mary had them removed and replaced with diamonds.
The pearls now feature on the Queen Mary's Lover's Knot tiara, worn by the Duchess of Cornwall and Cambridge these days.
Queen Alexandra's Kokoshnik tiara is part of the royal collection.
It was presented to Queen Alexandra, when Princess of Wales, for her 25th wedding anniversary in 1888 by the 'Ladies of Society' - 365 peeresses of the United Kingdom.
It is based on the traditional Russian headdress called a 'kokoshnik', which became popular as a style of tiara in Western Europe in the late nineteenth century.
Designed by Garrard, it was one of Queen Elizabeth's favourite tiaras and was also loved by her grandmother, Queen Mary.
The tiara can also be worn as a necklace.
Queen Elizabeth wore the stunning headpiece, pictured here, during her visit to Turkey in 2008.
Worn by Queen Elizabeth regularly throughout her 70-year-reign, the Grand Duchess Vladimir tiara is one of the most impressive in her collection.
The tiara originally belonged to Grand Duchess Maria Pavlovna of Imperial Russia, the cousin of Tsar Nicholas II. It was made by Romanov court jeweller Bolin.
The Romanovs, who ruled Russia for 300 years, were said to have a collection of jewellery worth more than $700 million. After the revolution much of it mysteriously went missing, was looted from royal residences or broken apart and the stones sold separately. The fate of most of the Romanov pieces remain a mystery but not the Vladimir tiara.
The duchess and her family fled Russia during the revolution and left her jewels, including the tiara, hidden in a vault inside a wall at the Vladimir Palace in St Petersburg.
The tiara was later smuggled out of Russia by a British intelligence officer, who was a friend of the Grand Duchess, posing as a worker.
It was returned to her family and later sold at auction to Queen Mary, Queen Elizabeth's grandmother.
In December 2019, Her Majesty chose to wear the tiara with its emerald drops for the Diplomatic Reception at Buckingham Palace.
The original Vladimir tiara contained pearl drops and diamonds, but Queen Mary had it altered so the jewels could be swapped for her emeralds.
Queen Elizabeth frequently wore the tiara in both the pearl and emerald settings.
She is pictured, here, wearing the tiara with its peal drops, during a State Banquet at the Presidential Palace in Lithuania, in 2006.
Her Majesty had the peal drops removed from the Vladimir tiara when she travelled to Estonia as part of the Baltic States tour in 2006.
The Brazilian Aquamarine tiara was commissioned by the Queen herself, to match a pair of earrings and a necklace already in her collection.
Her Majesty was gifted the aquamarine stones, surrounded by diamonds, from the people of Brazil on the occasion of her coronation in 1953.
They were made into earrings and a necklace, which the Queen wore often before asking Garrard to create a matching tiara in 1957.
Her Majesty wore the tiara in 2011 during her official visit to Australia.
She is pictured, here, with British Prime Minister David Cameron at the Commonwealth Heads of Government Meeting in Perth.
The Queen's aquamarine parure (jewellery set) grew rather quickly when she was given more stones from Brazil, this time in the form of a brooch, bracelet and hair clip, in 1958.
And when the Queen made her first state visit to Brazil in 1968 she was presented with an even larger stone.
That became the new centrepiece of her tiara, which she had remade in 1971.
The tiara was one of the most striking in Her Majesty's collection and it's no wonder she wore it when the Spanish royals visited Buckingham Palace in 2017, with Queen Letizia wearing her own, very impressive, Fleur-de-Lys tiara.
The Nizam of Hyderabad was one of the world's richest men and showed his wealth by gifting Princess Elizabeth a diamond necklace and tiara for her wedding in 1947.
Made by Cartier, the tiara featured an English rose design, with three detachable brooches.
Princess Elizabeth wore the Nizam of Hyderabad tiara during a visit to Ottawa, in Canada, in 1951, pictured here.
The matching necklace has been worn twice by the Duchess of Cambridge recently, while the Queen occasionally adds the brooches to her outfits.
But, sadly, the tiara was dismantled to create the Burmese Rubies tiara.
Her Majesty asked Garrard to create a new tiara in 1973, using stones from the Nizam of Hyderabad head piece.
The diamonds were set alongside a collection of 96 red rubies, presented to the Queen from Burma (now Myanmar) on the occasion of her wedding.
The design of the tiara was inspired by the Tudor Rose, with rubies said to offer its wearer good luck and protection.

Most recently, it was seen on the Queen for a State Banquet in honour of US President Donald Trump's visit to the UK, in 2019.
Much was said about the Queen's choice of tiara, with some pointing to Garrard's original description of the tiara which read: "The 96 rubies are a symbolic gesture, as rubies in Burmese culture protect from illness and evil, in this case to protect the wearer from the 96 diseases that can afflict humans".
More likely, the Burmese Ruby and Diamond tiara was chosen because of its colours - red and white feature in the American flag.
The Orient Circlet tiara was one of four pieces designed by Prince Albert for Queen Victoria, inspired by Indian designs he saw at the Great Exhibition, some of which were later presented to the Queen by the East India Company.
When Queen Victoria died, she left the tiara to the Crown for future queens and queen consorts to wear.
Originally featuring opals, Queen Alexandra replaced the stones with red rubies that belonged to Queen Victoria because she considered opals to be unlucky.
It passed into the collection of the Queen Mother, who loved the tiara and wore it frequently right until her death in 2002, even though it technically belonged to Queen Elizabeth who became monarch in 1952.
Queen Elizabeth wore the tiara, here, during an official visit to Malta in 2005, believed to be the only time it's been seen on the current monarch in public.
This tiara was made to match pair of sapphire and diamond earrings, and a necklace, gifted to the Queen by her father, King George, on her wedding day.
The parure is often known as the King George VI Victorian suite, as the stones are thought to have been made during the 1850s.
In 1963, Queen Elizabeth had the tiara made along with a bracelet.
The set features blue sapphires cut in various shapes including emerald, cushion and pear-shaped stones.
She is pictured, here, wearing the parure on board the Royal Yacht Britannia during a visit to France in 1992.
The Diamond diadem is also known as the King George IV State diadem.
It was the oldest in Her Majesty's collection, made in 1820 for King George IV's coronation in 1821, by Rundell Bridge and Rundell.
Set with 1,333 diamonds, including a four-carat pale yellow brilliant diamond in the centre of the front cross.
The diadem incorporates roses, shamrocks and thistles - the national emblems of England, Ireland and Scotland.
Because it was originally made for a man, the diadem has been resized several times throughout its history.
The Queen wears this tiara for the State Opening of Parliament, and is pictured, here, in 2007.
While this is not technically a tiara, the Imperial State crown deserves a mention due to its iconic association with the monarch.
Made in 1937, the Imperial State crown features the 317-carat Cullinan II diamond, the second largest clear cut diamond in the world.
It also consists of five rubies, 11 emeralds, 273 pearls, and 2868 smaller diamonds.
The Black Prince Ruby (the heart of the cross) is actually a red spinel.
The world's largest clear cut diamond, the 530.1 carat Cullinan I, is set into the Sovereign's Sceptre with Cross, which she holds.
