“The sapphire and diamonds are set in a slim 18 carat white gold band, which accentuates the central piece and draws the eye into those incredible stones.
“A family heirloom, Kate’s ring once belonged to Prince William’s mother, Princess Diana, and has incredible sentimental value to the Prince.
“William explained that by Kate wearing his mother’s engagement ring, he felt that Diana was with them on their wedding day.”
The royal has also used important pieces of jewellery to mark other special events in her life, the expert continued.
She may have done this when wearing a pair of drop diamond and pearl earrings after the birth of Prince George.
Lorna continued: “I think everyone remembers the photos from the hospital after Kate gave birth to the lovely Prince George – a new generation of the Royal Family had arrived.
“Kate’s signature style just shines through in their first photoshoot as a new family – her trademark pearl earrings are so classic and really convey her sophisticated motherly image.”
The timeless earrings featured a pearl hanging from a thin diamond chain.
“It’s such a sweet image of the family together and Kate looks radiant in a lovely lemon dress and fascinator.”
Lorna added Kate has worn the subtle necklace several times and it was thought to be given to her when she was a child.
“She’s wearing another favourite piece of hers which we see popping up time and time again,” she concluded.
“It is a diamond-encrusted cross pendant reported to have been gifted to her as a child.”
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.
