Princess Kate wowed in a vintage-inspired dress at a reception for Cancer Research UK on June 2, and along with her bright red Rodarte midi, she wore an old favorite pair of ruby earrings and a matching necklace. Along with being a perfect match for her dress, the jewelry set holds a deeper meaning, according to Justin Daughters, Managing Director at antique jewelry specialists Berganza.
The Princess of Wales’s ruby necklace, which she debuted during a 2017 tour of Poland, looks nearly identical to her sapphire engagement ring, featuring a large ruby surrounded by diamonds. The princess paired the necklace with a pair of coordinating ruby and diamond drop earrings she debuted in May 2025.
