The Queen has an extensive collection of jewellery, with an array of brooches included.
She sometimes lends her brooches to daughter-in-law Kate Middleton, and has many that only come out on special occasions.
Most are merely to accessorise her ensembles, but one of which is a piece she has held dear to her heart since she was a teenager.
Her Majesty has badges to symbolise her role in the Grenadier Guards, where she is the Colonel-in-Chief.
The Grenadier Guards is an infantry regiment of the British Army, and Queen Elizabeth II was given the title of Colonel-in-Chief in 1942.
The 91-year-old Monarch was handed badges to symbolise her position in the military, and has been pictured wearing three of them in public.

She is thought to have more in her collection at Buckingham Palace.
One of the badges shows the crown over the Royal Cypher, with “Evil be to him who evil thinks” as an inscription.
Elizabeth II also has a Cap Badge of The Grenadier Guards, rendered in the form of a fired grenade, which is usually worn on headgear, but she opts to wear it pinned to her front.
The third badge is is the Brigade of Guards brooch which combines all the regiments of the guards; Grenadier, Coldstream, Scots, Irish, and Welsh Guards.
It bears the inscription: “quinque juncta in uno”, which means “five joined as one”.
It’s not just brooches the Queen treasures, she has a special collection of pearl necklaces and tiaras.
