Considering she has spent a crazy amount of money on clothes this year (the Duchess refuses to let designers dress her for free), Kate's jewellery collection must be pretty damn impressive.
But what we didn't know was that for years the mother-of-two has silently been paying homage to the mother-in-law she never knew, Princess Diana.
According to The Mirror, When Kate gave birth to Prince George in 2013, her sister, Pippa Middleton, gifted her a simple Merci Maman gold pendant with her firstborn son's name engraved.
The thoughtful gift echoes a Merci Maman necklace that Princess Diana was given by husband Prince Charles after the birth of their son Prince William in 1982.
The jewellery brand confirmed the purchase in a blog post to their website, saying: "Family was one of the closest things to Diana’s heart so it’s no surprise that this shone through in her jewellery, featuring personalised pieces and meaningful charms."
"The young Lady Spencer owned a simple gold chain bearing her initial ‘D’, keeping her early jewellery minimal and personal."
"Upon the birth of Prince William in 1982, Prince Charles gave Diana the gift of a gold pendant engraved their new son’s name, which she always wore close to her heart."
"In 2013, Pippa Middleton continued this family tradition by giving her sister Kate, The Duchess of Cambridge, our Personalised Duchess Necklace to celebrate the birth of Prince George."
"Featuring a hand-engraved disc with the Prince’s full name, a small boy charm and a heart engraved with a ‘W’ to represent Prince William."
