In March, the 42-year-old announced she was beginning a course of preventative chemotherapy.
Oncology pharmacist Dazhi Liu claimed this could explain why Kate removed her wedding ring.

"Chemotherapy can cause fluid retention in the hands, which might make rings tight and difficult."
She continued to tell Hello!: "Metal rings could interfere with the radiation therapy and cause issues such as burns on the skin around the ring."
Liu added: "Since patients are at high risk of getting infections during chemotherapy, removing rings can help prevent skin infections.
"Overall, taking off rings during cancer treatment can help avoid these potential problems."

Given that Kate is still wearing her sapphire engagement ring and her new special ring, the most likely reason for the princess removing her wedding ring is due to it becoming tighter.
The special ring looks very similar to the promise ring gifted from Prince William to Kate during their university days.
Jeweller Steven Stone said: "During their university days, William gave Kate a promise ring, and though it’s hard to be certain, recent footage of the royal couple suggests she may be wearing this sentimental piece again.
"The ring is set on a rose gold Victorian band, featuring two garnets - Kate’s birthstone - and pearls to represent William’s June birthstone."
