Prince William and Kate Middleton at Charing Cross Hospital on Jan. 8, 2026.

The move marked a departure from her recent jewelry style, as the Princess of Wales started wearing a stack of rings in 2024 and continued layering the bling in 2025.

However, there was likely a practical reason behind why she wore just one ring for the hospital stop on Thursday. The royal may have been respecting common hospital policy to keep jewelry to a minimum to reduce the spread of germs.

Princess Kate has similarly skipped her 18-carat sapphire engagement ring that previously belonged to Princess Diana and a white gold and diamond Annoushka ring for previous hospital stops, and she wore only her gold wedding band for hospital visits in 2018 and 2020.

The jewelry rule isn’t ironclad, though, as she wore a sparkly stack of rings while touring The Royal Marsden Hospital in London in January 2025.

That appearance came with the announcement that the Princess of Wales received treatment from the Royal Marsden during her cancer journey, and she shared later that day that she was in remission.

Princess Kate also had rings on, including her sapphire engagement ring, when she visited the RHS’s Wellbeing Garden at Colchester Hospital in July.

The Princess of Wales made that engagement to highlight the healing power of nature, a force she has said uplifted her own recovery, and even got her hands dirty planting “Catherine’s Rose” plants, a new bloom named in her honor by the Royal Horticultural Society.
