Queen Camilla keeps her grandchildren close to her heart with touching ruby necklace at St James’s Palace

And while she was surrounded by the royal family, Queen Camilla found a way to keep her grandchildren close to her heart. Behind her elegant string of pearls was a hidden second necklace. Perhaps the Queen’s most personal piece of jewellery, this simple pendant features a ruby on one side (Queen Camilla’s birthstone) and on the other side is engraved with the initials of her five grandchildren from her first marriage to Brigadier Andrew Parker Bowles.
