Kate Middleton and Prince William, both 38, tied the knot on April 29, 2011. She has a stunning sapphire engagement ring that once belonged to Princess Diana. This is why she was given another ring from her husband.
In line with royal tradition, this was made from a special nugget of Welsh gold.
However, it was a few years later that the Duchess of Cambridge caught attention with another ring.
Shortly after the birth of her first child Prince George in 2013, royal fans spotted a third ring on her wedding finger.
This is thought to be an eternity ring with an adorable meaning, according to 77Diamonds.com managing director Tobias Kormind.
Analysing pictures for Express.co.uk, he said: “The gift of an eternity ring is an enormously romantic gesture that every woman dreams of.
“It represents undying, everlasting love – this is why it usually features identically-cut diamonds set all around the band to symbolise an eternal bond.
“Eternity rings usually celebrate wedding anniversaries or other special occasions. They are a profound promise of life-long companionship.”
As the ring was first noticed after the birth of Prince George, the Duke of Cambridge may have given it to Kate as a sign of commitment to his family.
“It has a continuing line of round brilliant diamonds thread and grain set into the band, to enhance the brilliance of the stones.
“A thread and grain setting is where the gold metal border is visible around the diamonds and there are small precious metal claws holding each individual diamond.
“I estimate a ring like this would be priced at around £1,500 to £2,000 on the high street.”
How did Kate Middleton become a royal?
Kate Middleton, or Catherine, Duchess of Cambridge, was born on 9 January 1982 at the Royal Berkshire Hospital, Reading, England.
She was born to Michael and Carole Middleton, a former flight dispatcher and air hostess. The couple founded a party supplies company, Party Pieces, in 1987 – now estimated to be worth £30 million.
Kate has a younger sister Pippa Matthews, 34, and a younger brother James Middleton, 31.
Kate and her family moved to Amman, Jordan, in 1984, where the future Duchess was educated at an English-speaking nursery school.
After moving back to Berkshire the family sent Kate to private school, St Andrews School. She went on to briefly study at Downe House before moving onto Marlborough College where she boarded.
For university the young Kate attended the University of St Andrews in Fife, Scotland. Here she was awarded an undergraduate MA (2:1 Hons) in history of art.
Relationship with Prince William
Kate met Prince William when they were both studying at St Andrews, and both living in St Salvator’s Hall. Famously, William reportedly took a fancy to Kate after she wore a see-through dress during a fashion show.
In 2003 the couple began dating and lived together during their second year of university.
The couple split in April 2007, however, in October they were back together.
Prince William proposed to Kate Middleton with his late mother Princess Diana’s engagement ring in October 2010. The couple were holidaying in Kenya at the time.
On 29 April 2011 they married at Westminster Abbey with a whopping 26 million watching the event live.
Kate wore an Alexander McQueen dress worth a reported £250,000 on the big day.
Kate assumed the title “Her Royal Highness The Duchess of Cambridge” and also became the Duchess of Cambridge on the day.
