Kate Middleton, 39, has worn many lavish pieces of jewellery including tiaras, necklaces and rings. She will often wear rings from her private collection as well as ones she has been gifted by Prince William, 38.
Prince William proposed to his wife in 2010 and gave her a sapphire and diamond engagement ring.
The lavish jewel, thought to be worth £300,000, previously belonged to Princess Diana.
Since the couple wed in April 2011, Kate has rarely been seen without the iconic jewel.
The mother-of-three will usually wear it with her Welsh gold wedding band and an eternity ring believed to have been given to her by the Duke of Cambridge when Prince George was born.

As working royals, Kate and Prince William have switched to virtual engagements due to the coronavirus crisis.
Whether stepping out or appearing virtually, the Duchess will attract attention with what she is wearing.
The royal has an enviable wardrobe to match her extensive jewellery collection.
Aside from royal jewels, Kate has also worn some pieces that could have more sentimental meanings.
Kate has worn an eye-catching citrine ring several times while in the Royal Family.
The piece of jewellery has a large citrine jewel and is yellow in colour.
She first wore the jewel before her wedding and it could be worth a small fortune, Ben Johnson, Managing Director at Miltons Diamonds, explained.
“The ring looks like a very large citrine stone to me and judging by the size of it could be worth anything from £5,000 up to £20,000,” he told Express.co.uk.
“Reports have suggested that this ring is a new addition to the Duchess of Cambridge’s collection, but there is proof she owned it already, as she was photographed wearing it on a night out with Pippa in 2008.”
Kate is a senior member of the Royal Family and has taken on increasing responsibilities over the years.
The expert suggested the citrine jewel has connotation which could align with her growing royal role.
He continued: “The citrine rock could also be making a reappearance because of what the stone is said to represent.
“It is widely claimed that the citrine crystal emanates optimism and can be used to direct personal will and decisiveness.”
The Duchess of Cambridge could have conveyed this message by wearing the piece on solo engagements, Ben added.
He said: “This would explain the motivation behind Kate’s decision to wear it on occasions when she is not accompanied by the Duke of Cambridge, attending events on her own terms.
“She is an experienced royal now, capable and independent.”
