Kate Middleton's borrowed royal jewellery in pictures: From diamond necklaces to glittering tiaras
The Duchess of Cambridge has an impressive collection of necklaces and earrings, but that doesn't stop her borrowing items from her royal relatives' jewellery boxes.
Kate very rarely wears a crown, but we've seen her sport three different pieces of headwear since marrying into the family in 2011. The most famous being Princess Diana's Cambridge Lover's Knot tiara, which she has worn four times so far.
And it's not the only bit of royal bling Kate has borrowed, here we look at all of the royal earrings, necklaces, tiaras and brooches she's worn.
The engagement ring Prince William proposed to Kate with during a trip to Kenya in October 2010 is famously a hand-me-down from his late mum, Princess Diana.
The 18-carat sapphire and diamond stunner was chosen by Diana, who died in 1997, after her engagement to Prince Charles in 1981 and cost £28,000. it was one of a series of pieces presented to Diana by jewellers Garrard.
Speaking of choosing the ring for Kate, William said: “It is very special to me. It was my way to make sure my mother did not miss out on today and the excitement that we are going to spend the rest of our lives together.”
Cartier halo tiara
The tiara Kate wore at her 2011 wedding to William had done the Royal rounds before being chosen to sit atop the most photographed head of the year.
Made by Cartier in 1936, the Halo tiara was an anniversary present from King George VI to the Queen Mother. She was photographed in the diamond headpiece, before giving it to the Queen as an 18th birthday present.
But Her Majesty didn't wear it much, and lent it to her younger sister Princess Margaret instead. She wore it often before her marriage to Anton Armstrong-Jones, but after that it went unseen until Kate did it justice on her wedding day.
Lotus flower tiara
In December 213, Kate was seen in a the lotus flower tiara at the Queen's annual diplomatic reception – the first time she had worn a tiara since her wedding.
The tiara was a reincarnation of a necklace made by Garrard jewellers and made into a tiara after the Queen Mum, then the Duchess of York, asked for the diamond and peal creation to be made into headwear instead in the 1920s.
Garrard was tasked with changing the piece that was then seen on the Queen Mum, Princess Margaret and later Kate.
Cambridge lover's knot tiara
This is one of the most famous tiaras in the royal collection and was made by Garrard commissioned by Queen Mary, in 1914. After she died in 1953, the tiara was passed to the Queen, who wore it regularly after coronation.
Of course, its most famous wearer is Princess Diana , who was given the headpiece as a wedding present from Her Majesty in 1981.
It had not been seen in public until 2015, when Kate wore it for the Diplomatic Reception at Buckingham Palace.
Prince William gave Kate his late mother's engagement ring, when he proposed to her and the loaning of her favourite crown to the Duchess of Cambridge was seen as another touching tribute.
Kate has since worn the tiara for 2016 and 2017's Diplomatic reception, and earlier in the year for the Spain state banquet.
Diamond and sapphire earrings
During Wimbledon 2011, Kate was seen sporting a pair of diamond and sapphire earrings while watching Andy Murray play .
The heavy studs – that match Princess Diana's cluster engagement ring – were among her most treasured jewels and were seen on her at numerous events during the 1980s and 90s. They were remodelled for Kate into drop earrings.
A courtier said: “Now they’re married, William wanted her to have some of his mother’s favourite pieces.”
The Queen Mother's Sapphire and Diamond Fringe Earrings
Kate has worn these striking earrings once so far, for the V&A 100 Women in Hedge Funds Gala in 2015.
They once belonged to Queen Mary, who paired them with the Russian Sapphire Cluster Brooch. They also match the Duchess' engagement ring.
Their history is relatively unknown, but the Queen has most likely inherited them from her mother's collection of jewels, although she has never worn them in public.
The Queen's diamond chandelier earrings
The Duchess has worn these show-stopping earrings for numerous black-tie and formal occasions, the first being at the BAFTA event in Los Angeles, in 2011, and most recently for the Royal Variety Performance.
The delicate jewellery contains diamonds in a chandelier design, surrounding a larger pear-shaped gem in the middle. They are a loan from the Queen, but Her Majesty doesn't appear to have ever worn them in public.
Silver jubilee diamond and pearl earrings
Kate has worn the pearl drop earrings several times, but most notably during her 2016 royal tour of Canada.
They belong to the Queen and they used to be her go-to earrings for daytime engagements, but she now regularly loans them out to other family members.
Diamond pendant earrings
Similar to Her Majesty's chandelier earrings, these contain a pendant of separate stones hanging within a diamond frame.
According to the Queen's Jewel Vault, they first appeared at the State Opening of Parliament in 2012, but Kate has worn them more times in public, most recently for the Anna Freud National Centre gala dinner.
Bahrain pearl drop earrings
The pearl and diamond earrings were a wedding gift to the Queen from the Sheikh of Bahrain, in 1947.
They each consist of one large, three-pendant sized and four smaller diamonds, and a pearl.
Her Majesty wore them during the early years of her reign, but she has since loaned them to Kate for the Remembrance Sunday service in 2016.
The Collingwood pearl and diamond earrings
Kate wore Princess Diana's pearl and diamond earrings for the first time this year, at the Spain state banquet, along with her tiara.
They were given to the late Princess of Wales as a wedding present from Collingwood jewellers, and she wore them for numerous balls and formal engagements, including during her tour of the US.
Nizam of Hyderabad diamond necklace
Featuring 38 diamonds, the Queen received the necklace as a wedding present from an Indian potentate in 1947. She wore it for one of her official Queen of Canada portraits and loaned it to Kate for the National Portrait gala in 2014.
King George VI and Queen Elizabeth Bandeau Necklace
The V shaped necklace features a diamond and ruby collar, ending in a diamond drop pendant.
It was given to the Queen as a wedding gift from her parents King George VI and Queen Elizabeth. She wore the beloved piece on numerous occasions during her younger days, but appears to have swapped it for shorter chains in recent years.
The Duchess teamed the glittering necklace with a blush pink Marchesa dress for the Spain State dinner in July 2017.
The Four Row Japanese Pearl Choker
The Duchess wore this dazzling pearl choker for the Queen and Prince Philip's platinum wedding anniversary dinner this year.
The four-strand necklace was created from cultured pearls given to the Queen by the Japanese government. She wore the necklace herself on various occasions in the 1980s and 1990s, including on a visit to Bangladesh in 1983.
Diana, Kate's late mother-in-law, borrowed the piece for a state banquet in 1982 held at Hampton Court Palace in honour of the Netherlands.
Diamond collet necklace
Kate sported one of the Queen's diamond collet necklaces for the first time at the Diplomatic reception in December 2017.
It is believed to be one of two which were left to Her Majesty from Queen Mary's collection. She loved to wear several at once, but we have only seen one at a time on the Queen.
Queen Mary’s Diamond Bar Choker Bracelet
This gem originally belonged to the Queen's grandmother, Queen Mary, who wore the diamond jewels as a choker.
The Queen's wedding gift bracelet
Kate wore the Queen's wedding gift bracelet for the second time to the BAFTAs 2017. She first wore it to the China State Banquet in 2015, with Queen Mary’s Diamond Bar Choker Bracelet on her other wrist.
Its name is self-explanatory, but it was given to the Queen as a wedding present from Prince Philip, in 1947.
The geometric bracelet is made from diamonds taken from a tiara that once belonged to the Duke's mother, Princess Andrew of Denmark and Greece.
The Diamond Quatrefoil bracelet
The Quatrefoil bracelet was originally worn by The Queen Mother, and then passed down to Queen Elizabeth II. But this another piece from the royal vault, which has rarely been seen in public.
Kate wore it for the first time to the Anna Freud National Centre gala in November 2017, and it was last seen on Her Majesty for the State Opening of Parliament in 2010, according to the Queen's Jewel Vault
In March 2012, Kate sported a shamrock-shaped brooch as she mingled with members of the Irish Guards Regiment for Armed Forces Day.
The gold Cartier three-leaf piece centred with an emerald belongs to the regiment rather than the royal family, but had also been worn by the Queen Mum who had long been affiliated with the Irish Guards, attending her first St Patrick's Day in 1937 and first presenting the shamrock to the battalion in 1964.
The regiment even carried her coffin after she died in 2002, aged 101.
The shamrock has also been seen on Princess Anne.
Maple leaf brooch
The diamond piece had been loaned to her by the Queen for the tour as it is Canada's national symbol.
It had originally been given as a present to the Queen Mum by King George VI ahead of their tour of Canada in 1939 and it was treasured.
The Queen, as Princess Elizabeth, also wore the diamond-encrusted piece for her first trip to Canada in 1951 and wore it again as recently as 2010 – again for a trip to Canada.
The Duchess has since worn the piece again, for her tour of Canada in 2016.
The New Zealand Fern brooch
The intricate diamond and silver brooch was a gift from the women of Auckland to the Queen in 1954 on her Commonwealth tour.
The Duchess wore it twice on her visit to New Zealand in 2014, with her teal pleated Emilia Wickstead dress and with her striking red Catherine Walker coat.
Pearl and diamond leaf
According to the Royal Order of Splendor, the diamond and pearl leaf brooch's "provenance is so far unknown and its appearances are scarce; The Queen most notably wore it during a State Visit to South Korea in 1999."
Kate pinned it to her blush pink Catherine Walker coat for the Passchendaele anniversary in Belgium, in July 2017.
