PRINCESS DIANA VS. QUEEN CAMILLA: THE ENGAGEMENT RINGS FROM KING CHARLES THAT MAY HIDE A ROYAL STORY FEW PEOPLE TALK ABOUT At first glance, they are simply two beautiful engagement rings — dazzling jewels that once marked two of the most talked-about moments in modern royal history. But royal watchers have long noticed that the rings King Charles gave to Princess Diana and later to Queen Camilla seem to tell a deeper story, one that quietly reflects two very different chapters inside the palace walls. When Diana stepped into the spotlight in 1981, her sapphire engagement ring instantly became one of the most recognizable pieces of jewelry in the world. Cameras flashed, crowds cheered, and the ring quickly became a symbol of the royal fairy tale that captivated millions. Years later, when Charles proposed again, the ring chosen for Camilla carried an entirely different kind of history — a vintage royal heirloom linked to a previous generation of the monarchy. The choice surprised many at the time, and some royal observers believe it revealed more about the palace’s thinking than the public ever realized. On the surface, it’s a simple comparison of two rings. But behind the sparkle, there may be a quiet detail — something subtle in the story of how and why each ring was chosen — that few people noticed when those moments first unfolded.

The Gist

  • Prince Charles (now King Charles III) married Lady Diana Spencer in 1981. 24 years later, he wed Camilla Parker Bowles.
  • The rings Charles proposed with are a study in contrasts, differing in terms of color, cut, carat size, and price.
  • One of the engagement rings is worth double the value of the other—for good reason.

King Charles has been engaged and married twice. His first trip down the aisle was for his ‘wedding of the century’ with Lady Diana Spencer on July 29, 1981. The former couple divorced in August 1996. Nearly 10 years later, he wed again, marrying partner Camilla Parker Bowles in a quiet 2005 ceremony.

The palace announced the future king’s engagement to Diana on February 24, 1981, five months before they married at St. Paul’s Cathedral in a highly publicized ceremony. (Camilla, now Queen Consort, was in the audience the day of the announcement, having dated Charles before marrying first husband Andrew Parker Bowles in 1973.)

Many moons later, Charles and Camilla’s engagement was announced on February 10, 2005; the longtime couple (whose relationship overlapped with Charles’s marriage to Diana) would marry two months later at Windsor Castle.

Just as the two relationships are marked by different trajectories, Diana and Camilla’s engagement rings couldn’t be more different. Here’s how Princess Diana and Queen Camilla’s engagement rings compare, from their designs and histories to who got the more expensive sparkler.

It’s perhaps the most famous royal engagement ring of all time. Ahead of Charles’s proposal to Diana, he had his girlfriend select a ring from a collection of options at Windsor Castle, per People. Diana reportedly chose a striking 12-carat Ceylon sapphire bauble from Garrard because it matched her blue eyes. The central stone is surrounded by a halo of 14 accent diamonds set in white gold.

Since the ring came from Garrard’s catalog, anyone could buy it—making it an unusual choice for a royal bride-to-be. Per Vogue, Charles’s relatives didn’t approve of the proposal piece because anyone could have access to it and it wasn’t bespoke like previous princess’s rings. Diana nevertheless loved the sparkler, and continued to wear it after her divorce.

Today, the late Princess of Wales’s ring belongs to her daughter-in-law, Kate Middleton. When Diana’s son Prince William proposed to Middleton in 2010, he gifted her the iconic bauble. “I thought it was quite nice [to use Diana’s engagement ring] because obviously she’s not really around to share any of the fun and excitement of it all. This is my way of keeping her sort of close to it all,” William told ITV in his and Middleton’s engagement interview.

Two months before their intimate wedding, Charles and Camilla announced their engagement on February 10, 2005. He popped the question with a platinum engagement ring with a 5-carat emerald-cut diamond with three baguettes along either side—what Town & Country described as “an Art Deco design.”

The outlet added that “the piece is believed to have come from the Queen Mother’s collection—she was seen wearing the ring in the 1980s—though its origins prior to that are unclear.” Brides reported, however, that the ring was given to the Queen Mother by her husband, King George VI, on the occasion of Queen Elizabeth’s birth in 1926.

Diana’s engagement ring is worth nearly double the value of Camilla’s today.

In 1981, Princess Diana’s ring cost between $37,500 and $60,000; in today’s dollars, it’s worth approximately $520,000. But, as Brides put it, “several factors contribute to the high price tag of the sparkler, including inflation, the rarity of the jewels, and the fact that it’s now Kate Middleton’s engagement ring.”

Contrast that with Camilla’s heirloom jewel, which is estimated to be worth $288,000, according to Brides—significantly less money than Diana’s (and now Kate’s) memorable sparkler.

Charles and Camilla celebrated their 20th wedding anniversary in 2025. When asked what their secret to a happy marriage is, Camilla pointed to “laughing at the same things” as what has kept them together for so long.

Not only were their engagement rings polar opposites, but the manner in which each proposal went down reflected the differences between Diana and Camilla’s relationships with Charles.

In Andrew Morton’s 1992 biography of Princess Diana, Charles and Diana’s proposal is “described as brief,” according to Town & Country. Apparently Charles and Diana were in the nursery at Windsor Castle when Charles “asked her simply to marry him.” Diana’s response? A giggle, thinking it might be a joke.

“The prince was deadly serious, emphasizing the earnestness of his proposal by reminding her that one day she would be Queen,” Morton wrote. But Diana had a “small voice inside her head [that] told her that she would never become Queen but would have a tough life.” Regardless, Diana said yes, and told him repeatedly how much she loved him. “Whatever love means,” Charles replied—a line he would infamously repeat in their engagement interview.

When Charles proposed to Camilla, he’d known her for 35 years, and unlike with Diana, got down on bended knee for their proposal, as Camilla told The Telegraph. “Of course,” she said when asked if Charles got down on one knee. “What else?”
