This includes one brooch, an image of which was posted on the Queen’s Instagram account. The Royal Family Instagram account paid tribute to emergency service workers in the UK.
Not only has the Queen worn the piece to carry out duties, but she has worn it for very important sentimental events too.
The piece, which is made of gold, is large and round and features over 60 diamonds, was a gift from President of Singapore.
Given to the Queen in 2012 for the Diamond Jubilee, it has an interesting history.
The Peranakan Chinese people are descended from immigrants to the Peninsular Malaysia and Singapore.
This style of jewellery is synonymous with Peranakan Chinese people.
Elizabeth II wore the piece for her great-granddaughter Princess Charlotte christening.
The Queen last wore the piece this year for Church at Sandringham on January 26. The fact Her Majesty takes the brooch to her country home with her shows it is quite the favourite.
As well as to church, the Queen often wears this brooch to another favourite type of a event of hers, the horse races.
She wore the piece to the Royal Windsor Cup in 2018, and has worn it to the first day of Ascot and the Epsom Derby.
The Queen gave another important piece of jewellery to Kate Middleton.
Kate has worn the Diamond Quatrefoil Bracelet on a number of occasions.
The huge glittering diamond bracelet has emotional significance for Her Majesty as it belonged to the Queen Mother.
The Queen Mother wore the piece as of 1958, although it is not known if the bracelet was a gift to her or a piece she bought or commissioned for herself.
