Kate Middleton debuts new necklace dedicated to her three children

How charming!

On Tuesday, Kate Middleton visited with parents and children in London’s Battersea Park wearing a new gold necklace adorned with “G,” “C” and “L,” the initials of her three children with Prince William: Prince George, Princess Charlotte and Prince Louis.

The Duchess of Cambridge, 38, layered the sweet and sentimental piece with a second double-strand necklace from Spells of Love ($108). She dressed casually for the occasion, choosing a white puff-sleeve Ralph Lauren top ($79.50), rose-colored cropped trousers from Marks & Spencer and comfy Superga sneakers ($65).

Middleton’s sister-in-law Meghan Markle has similarly used jewelry to pay tribute to Archie, her son with Prince Harry. Last year, she attended Wimbledon wearing a gold necklace with a letter “A” pendant from Verse ($509), and her diamond eternity ring features her birthstone along with Harry’s and Archie’s.
