Royal Ascot is in full swing, and even just two days in, it’s already delivered some truly standout style moments.
Travelling in the first carriage alongside King Charles, Prince William, and Prince Saud bin Khalid Al-Saud, Queen Camilla stood out in an elegant green ensemble with a coordinating hat. As is tradition, she selected a brooch of deep personal and historical significance to complete her look.
Today, she wore the Cambridge Cluster Emerald and Diamond Brooch with its striking emerald pendant – a piece passed down to Queen Elizabeth II from her grandmother, Queen Mary, in 1953. The late monarch notably wore it for her golden wedding anniversary.
Fine jewellery experts at UK retailer Steven Stone have taken a closer look at the brooch, uncovering its fascinating history and value.


“Queen Camilla’s brooch originally belonged to Queen Mary, the grandmother of Queen Elizabeth II, and was passed down to the late monarch in 1953 – the year of her coronation. Crafted in silver and gold, the brooch features a striking central cabochon emerald surrounded by a cluster of brilliant-cut diamonds, reflecting the expert craftsmanship of the late Victorian and Edwardian eras. Enhancing its elegance and versatility, it has a detachable emerald pendant.
A deeply symbolic choice, emeralds represent rebirth, renewal, and enduring love. Queen Elizabeth II wore the brooch on several significant occasions, most notably for her Golden Wedding Anniversary in 1997, marking 50 years of marriage to Prince Philip.
A treasured and valuable piece within the royal jewellery collection, I’d estimate its worth to be around $50,000.”
