They stated: “Kate’s engagement ring is incredibly famous, known for sparking a huge increase in sales of sapphire engagement rings back in 2010.
“It features a 12-carat oval sapphire set in 18k white gold, surrounded by 14 solitaire diamonds. Created by Garrard & Co. (the former Crown Jeweller), it is now valued at around £300,000.
“However, much of its value is sentimental: this engagement ring was passed down from Princess Diana, William’s mother.”
As well as wearing the family jewel, Kate has two other rings she will often wear on her wedding finger.
When Kate and Prince William married, she was given a Welsh gold wedding band in line with royal tradition.
The ring was made from the material used to create rings for royals including the Queen, Sophie, Countess of Wessex and Meghan Markle.
Before it was Kate’s, the jewel was given to Prince William by the Queen.
“Kate’s simple gold wedding ring is crafted from a special nugget of Welsh gold (a tradition dating back to 1923) by Wartski, a jewellers based in London,” the experts added.
The mother-of-three started to wear a white gold band believed to be an eternity ring gifted from Prince William.
The experts continued: “The third ring she wears is an eternity ring. Eternity rings are often used to mark special milestones in a relationship – in this case, it was a gift from her husband to mark the birth of their first child, Prince George. Made from 18ct white gold, it features 0.23ct of white diamonds. Kate’s eternity band comes from London-based designer Annoushka, and is valued at £1,200.
“In terms of why she wears three rings on one finger, many women choose to wear all three rings (wedding, engagement and eternity) on their wedding finger following marriage.
“The order in which these are worn actually has a great significance: wearing your wedding ring first means it is closest to your heart, followed by the engagement and then eternity ring. It looks like Kate Middleton follows this tradition.”
The royal line of succession – who outranks who?
The line of succession to the British throne dictates the order in which each member of the Royal Family would ascend to the throne.
It is also seen as a ranking of importance with the head of the line, the Queen, taking the place of ruler.
Older children come before younger children. Traditionally boys came before girls, but this law was changed on 26 March 2015 before the birth of Prince William’s first child.
Incredibly, Catholics are still excluded from the line of succession, as are children born outside of wedlock.
The royals, who usually stick to a strict protocol when appearing in public, often arrive at events in ascending order of importance, with the most important royal arriving last.
Prince Charles, 72, is currently first-in-line to the British throne, followed by Prince William, 38, his oldest son.
Then comes Prince William’s children, George, seven, Charlotte, five, and Louis, two, and they are followed by Prince Harry, 36. Prince Harry is succeeded by his son Archie Harrison, born in May 2019.
