However, for Camilla, there has been some controversy because she was not Charles's first wife. She was granted the title the Queen Consort by the late Queen Elizabeth II in February last year during the Platinum Jubilee.
The monarch, 74, has granted a new coat of arms to Camilla, 75, as revealed by The College of Arms in its April newsletter. Seen for the first time, the arms have been updated with the Crown of the Monarch, along with King Charles's updated shield on the left.
Camilla Parker-Bowles was born into an aristocratic family and has long been linked to the royal family – way before she even met King Charles.
In addition, this royal connection means that Diana and her husband Prince Charles were very distant cousins, via several lines. In particular, they each descend from a daughter of Henry VII: Margaret, who married James IV of Scotland, and Mary, who married Charles Brandon.
Camilla Is Related to Both Diana and King Charles
Strangely, they are also both related to the late Princess Diana through shared ancestry dating back to King Charles II. Also note that Camilla's great-grandmother was a mistress to King Edward VII, the great-great-grandfather of King Charles.
It turns out there has been no flight of fantasy in the penmanship of the show, as not only did the real Charles gift Camilla the exact same piece of jewellery with their pet names for each other, but he fobbed off Diana by telling her that it was a farewell gift for an ex-lover.
Camilla has continued to wear the tiara since marrying into the Royal Family.
According to tradition, King Charles III's wife Camilla would be the next to wear the jewel at this weekend's coronation ceremony. But she will wear a different crown, one with 2,200 smaller diamonds.
Camilla Wore Queen Victoria's Diamond Brooch at Elizabeth's Funeral.
Dubbed the "Coronation Necklace," the dazzling neckwear was originally made by British Crown Jeweler Garrard in 1858 for Queen Victoria and has been worn at every coronation since. The necklace features 26 cushion-cut diamonds, including the head-turning 22.48-carat dangling pendant called the "Lahore" diamond.
Why didn't Camilla wear a tiara when she got married? As she was not married in a church, Camilla did not wear a tiara for her wedding, as most royal brides do. Instead she donned a white hat designed by Philip Treacy for the ceremony, and a gold, feathered headpiece for the blessing.
Camilla doesn't have pierced ears, so she didn't wear the coordinating Coronation Earrings. Instead, she wore a pair of diamond drop earrings from her own collection.
Imperial State Crown
It was last at the state funeral of Queen Elizabeth II in September last year. Weighing 1.06 kg and measuring 31.5 centimetres in height, it is set with 2,868 diamonds, 17 sapphires, 11 emeralds, 269 pearls and four rubies.
The tradition is said to date back to the late 1800s, during Queen Victoria's reign. Following the death of her husband, Prince Albert, in 1861, the monarch famously wore black for 40 years in tribute and only accessorised with black or colourless jewellery – and pearls were her jewellery item of choice.
"Camilla stepped right back even before the engagement, she totally understood that her relationship with Charles was over," says Junor. "Therefore, Charles wouldn't have needed to tell her face-to-face. And I think it is absolutely untrue that she and Charles slept together just before the wedding.
In Spencer, Diana is horrified (though seemingly unsurprised) to discover her husband gave her the same pearl necklace he gave to his then-mistress, Camilla Parker-Bowles. There's no evidence to suggest this gift-giving snafu ever happened (or that she ate them at the dinner table).
Before King Charles III (then Prince Charles) married Princess Diana (then Diana Spencer) in 1981, he was apparently already smitten with his former girlfriend, Camilla Parker Bowles (then Camilla Shand, now Camilla, Queen Consort). After an extensive courtship, Charles and Camilla married each other in April 2005.
Her large jewellery collection, including the Crown Jewels, tiaras, brooches, diadems, and more, will continue to be maintained in a trust rather than in the monarch's personal collection. However, the Queen's private jewellery collection will be handed down via the Windsor family.
Prince William and Prince Harry's step-siblings Laura Lopes and Tom Parker Bowles made a rare appearance with the rest of the royal family during the state funeral of Queen Elizabeth on Monday, September 19. Laura and Tom are Queen Consort Camilla's children, and don't attend too many royal events.
The crown atop Queen Elizabeth II's coffin is the U.K.'s Imperial State Crown. It is the crown monarchs use for state occasions and after they leave their coronation at Westminster Abbey. During the moment of coronation, however, they use the bigger and heavier St. Edwards Crown.
The Princess of Wales wore a pair of pearl and diamond earrings that had once belonged to Prince William's mother. The Collingwood jewellery were gifted to then-Lady Diana ahead of her wedding to Charles and then handed to Kate after her marriage to William.
The royal paid homage to Her Majesty by wearing pearl drop earrings, a four-row Japanese pearl choker necklace with a curved diamond clasp, which once belonged to the Queen herself, and a matching multi-strand pearl bracelet.
One of Queen Camilla's closest aides is ruffling feathers in Buckingham Palace, as she takes on what might be the toughest job for royal aides. Jacqui Meakin is Dresser to the Queen, putting her in charge of choosing outfits for the most senior woman in the royal family.
Camilla did attend Charles and Diana's wedding in 1981. However, Princess Diana said that Camilla did not wear white, noting instead that the future queen consort donned a light gray for the occasion.
When Camilla married Prince Charles (now King Charles III) at the Guildhall in Windsor on April 9, 2005, she brought some French blood to the British royal family. The Queen was previously married to Brigadier Andrew Parker Bowles and the marriage was dissolved in 1995.
