The dazzling piece features a set of round brilliant-cut diamonds in 18K blackened white gold and yellow gold.

Meghan first wore the necklace in October 2018, during a reception in New Zealand as part of her and Prince Harry's royal tour.

And according to a jewellery expert, Meghan's accessory holds a hidden message, which she could have been aiming at the Royal Family amid the ongoing rift.

Nilesh Rakholia, a jewellery expert and founder of Abelini, said Meghan's necklace has symbolic and monetary value.

She told Hello! magazine: "In jewellery, the spiral is a powerful symbol of eternity, growth, and the journey of life.

"It's a subtle but deeply meaningful choice for a public figure like Meghan, perhaps hinting at her own evolving story and journey."

Meghan paired her treasured piece of jewellery with a £219 black and white sundress by Veronica Beard, a brand favoured by both Princess Kate and Zara Tindall.
