Notably, the bracelet also appeared to be personalised by Camilla, managing director of jeweller William May Nick Withington stated.
He told Express.co.uk: “Camilla is thought to have presented the bracelet to Kate as a wedding gift.
“She was first pictured wearing the bracelet in June 2011, two months after her wedding to Prince William.”
On closer inspection of the jewel, the charm appears to show the personalisation.
It is engraved with an illustration of a crown and two ‘C’s, which seem to relate to the names of the royals.
“The bracelet is a classic chunky curved link with an engraved disc charm,” Nick continued.
“Double sided, the disc is engraved with a ‘C’ for Catherine and a coronet and the reverse side a ‘C’ for Camilla and a crown.”
Kate has worn the timeless bracelet a number of times since her wedding.
Kate was given a range of jewellery on her big day.
She walked down the aisle wearing a pair of drop diamond earrings believed to be a gift from her parents.
The mother-of-three also borrowed a tiara from the Queen, as many royal brides will do.
She chose the Cartier Halo tiara which has now become synonymous with her royal wedding.
