Today we’ll wrap up our All That Glitters series examining the borrowed jewelry the Duchess of Cambridge has worn. Our final topic: tiaras. (If some of this sounds familiar, it was covered in a March post when I was desperately casting about for a topic to distract us from the early days of the pandemic, and I put together a tiara poll.)
We begin with the very first tiara we saw the Duchess wear, the Cartier Halo. 
UPDATE WEDNESDAY MARCH 25: There is news today that Prince Charles has tested positive for coronavirus. Clarence House released a statement with the news, saying he has mild symptoms but is otherwise in good health. More from the BBC:
Prince Charles, 71, is displaying mild symptoms “but otherwise remains in good health”, a spokesman said, adding that the Duchess of Cornwall, 72, has been tested but does not have the virus.
Charles and Camilla are now self-isolating at Balmoral.
Buckingham Palace says The Queen is in good health and last saw the Prince on March 12th. BP also says HM is following “appropriate advice with regard to her welfare.” The Clarence House statement adds “It is not possible to ascertain from whom the prince caught the virus owing to the high number of engagements he carried out in his public role during recent weeks.”
William and Kate are believed to be at Anmer Hall with George, Charlotte, and Louis. I will update with any new information or do a separate post should circumstances warrant.

We are back with a look at a favorite topic for many a royal fashion follower, Kate’s tiara appearances!
I thought we would go chronologically and start with the Cartier Halo tiara worn for Kate’s wedding in April 2011. Below, two shots of the Duchess: on the left, she is seen on the way to the Abbey, perhaps doing a little deep breathing; on the right, after the service. 
We are back with several engagements added to Kate’s Calendar, as well as that much-dicussed jewelry poll.
We begin with the new engagements:

They will then travel to Kensington Palace where they will drop in on a screening of a documentary about Jonny’s experience… Jonny regularly attends screenings with young people as a way to encourage open discussion of mental health issues.
Around 20 young people from a South London school will be invited to watch the screening at Kensington Palace and then take part in a discussion, led by Jonny, Neil and Rethink Mental Illness. The children taking part in the session are from a school where Jonny has previously delivered his ThinkWell project.

Kate wore the Cambridge Lover’s Knot Tiara for this evening’s diplomatic reception at Buckingham Palace. It is a glittering white tie affair, the largest function of the year at the Palace. Below you see Kate and William arriving for the event.
