Kate Middleton pays sweet tribute to Prince George, Princess Charlotte and Prince Louis during recent appearance

After months spent in lockdown in the UK, Kate Middleton ventured out this week to London's Battersea Park to speak to families about parent-to-parent support programs.

But for royal watchers, the real star of the show wasn't the Duchess of Cambridge herself, but her new gold necklace.

A lover of sentimental jewellery, the mother-of-three debuted a dainty gold necklace featuring three individual discs.

Upon closer inspection, the circular charms are each engraved with a tiny 'G', 'C' and 'L' - a sweet nod to her three children Prince George, seven, Princess Charlotte, five, and Prince Louis, two.

The 38-year-old layered the meaningful piece with another necklace by Welsh designer Hayley Jones.

The accessories complemented her square-neck top with puff sleeves, white sneakers and rose-hued trousers.
