The story behind the pearls in Camilla’s anniversary portrait

Yesterday marked Charles and Camilla's 14th wedding anniversary, and for the special occasion, the couple shared a new portrait on the Clarence House Instagram account.

The black and white portrait, shot by Alexi Lubomirski (the photographer behind Harry and Meghan's engagement portrait), shows the couple smiling at each other.

You can't see much of the Duchess of Cornwall's outfit, however royal fans have spotted that it's the same white floral embroidered Fiona Clare dress she wore to Prince Louis' christening.

She accessorised it with pearl earrings, and a beautiful pearl and diamond statement necklace. This particular piece is actually one of Camilla's favourite necklaces of all time, and looking back at pictures of her across the years, you'll notice she wears it a lot.

It features four strands of pearls, all joined at the centre by a circular diamond clasp. She has been wearing the piece since 2010 (that we know of), so this could well be a present from Prince Charles' for the couple's fifth anniversary, though of course this hasn't been confirmed.
