The Queen was known for having a spectacular jewellery collection, including a range of tiaras, crowns, brooches, necklaces, rings and more.
And despite owning a jewellery portfolio worth millions of pounds, the late monarch was reportedly buried in just two precious pieces of jewellery - her wedding band and pearl earrings.
Now, it's been revealed one of the last pieces of jewellery worn by the Queen in public - a Platinum Jubilee Brooch - has been replicated and will be available for the public to view.
The diamond-encrusted pin is ready for display at the Goldsmiths' Fair in London, which opens to the public on Tuesday for a two-week exhibit.
It's a duplicate of the design Her Majesty wore to the Principal Platinum Jubilee Beacon at Windsor Castle in June, for the first night of the four-day Platinum Jubilee to mark her 70-year reign.
Goldsmiths released a statement explaining the platinum pin was personally picked as a gift from The Goldsmiths' Company for her Jubilee celebrations.
Designed by fine jeweller David Marshall and his team, it 'represents the four nations and includes lily of the valley, which featured in The Queen's Coronation bouquet', according to the statement.
It was 'handpicked by The Queen from a shortlist invited from highly acclaimed U.K. jewellery makers' and then commissioned into production.
The glittering circular pin is stamped with a number on the back to distinguish it from the brooch the Queen wore to light the beacon in June.
While wearing the special piece, the Queen touched a globe symbolising the Commonwealth nations and a chain of lights being sent from Windsor Castle to Buckingham Palace.
More than 3,500 beacons were lit up globally to mark her Jubilee.
At the time, beacon pageant master Bruno Peek told People of the Queen: 'She's our country, our nation, and our Commonwealth, and I believe she's the person that everybody really looks up to.'
'She's got such continuity.'
At the Queen's state funeral on Monday, September 19, her great-granddaughter Princess Charlotte wore a diamond brooch that paid tribute to her.
The diamond design offsetting the seven-year-old's black mourning clothes came in the shape of a horseshoe, nodding to Her Majesty's passion for horses and horse riding. (When she was young, the Queen famously said: 'I should like to be a horse' when she grows up.)
Princess Charlotte's mother Kate Middleton paid similar tribute to Her Majesty when wearing a rarely seen pearl leaf brooch in the procession of the Queen's coffin to Westminster Hall on Wednesday, September 14.
Her Majesty was believed to have worn the stunning design during her visit to South Korea in 1999, per HELLO!.
