One eternity ring, a newer addition to the Princess’s jewellery box since 2025, is adorned with diamonds and sapphires, and is thought to be the Étincelle de Cartier wedding band. Many have speculated that the ring may have been a present from Prince William to mark the end of Kate’s course of preventative chemotherapy – and of course, it coordinates perfectly with her engagement ring.
A second ring, set with smaller diamonds for a pavé effect, is another relatively recent addition to Catherine’s jewellery collection, and goes well with her other pieces, given its subtle sparkle. The Princess’ third eternity ring is an older piece: a sparkling, diamond-encrusted style, it hails from Annoushka – one of Kate’s favourite jewellers – and is thought to have been a present from William following the birth of Prince George in 2013. The fourth and final thin band adorning the Princess’ finger is always, of course, her wedding ring, crafted from the same nugget of Welsh gold used for Queen Elizabeth’s own wedding band.
It was a return to The Treehouse for the Princess of Wales, who opened the hospice in March 2012, one of her earliest engagements as a newly married royal. Catherine was given a tour of the new expansion, seeing firsthand the construction of a new hydrotherapy pool, wellbeing and therapy suites, a dedicated space for teenagers, a larger care area, and additional bedroom space.
Her Royal Highness then met with some of the service users at The Treehouse, learning from the children and families receiving care and support about how the hospice offers creative therapies using music and holistic care to nurture each child’s emotional, social and developmental wellbeing – a cause that the Princess of Wales has long championed.
