Introduction: The Woman Behind the Jewels π
When we think of Princess Diana, many images come to mind: her compassionate humanitarian work, her revolutionary approach to royal parenting, her fashion-forward style. Yet among the most enduring symbols of her legacy remains her extraordinary jewelry collection β pieces that not only adorned a princess but told the story of a woman who transformed the British monarchy forever.
Diana's jewels were more than mere accessories; they were historical artifacts, diplomatic tools, and deeply personal expressions of her evolving identity. From her famous sapphire engagement ring to the Spencer family tiara, each piece carries its own fascinating story and continues to captivate royal watchers worldwide decades after her untimely passing.
In this comprehensive exploration, we'll journey through the most significant pieces in Diana's collection, unveil their origins and histories, analyze their astronomical values, and trace their journeys since her death β including which treasures now adorn the Duchesses of Cambridge and Sussex. We'll also reveal lesser-known facts about these iconic pieces that even dedicated royal fans might not know.
The Formation of a Royal Collection
Early Jewelry: The Spencer Family Heirlooms
Before she became a princess, Lady Diana Spencer already had access to some remarkable jewels through her aristocratic family heritage. The Spencer family, with its centuries-old lineage dating back to the Tudor period, possessed several notable pieces that would later become signature items in Diana's collection.
Most iconic among these was the Spencer Tiara, a family heirloom assembled in the 1930s from various pieces of jewelry owned by the Spencer family. The garland-style diadem, featuring diamonds set in silver and gold in various floral and scrolling designs, became one of Diana's most frequently worn tiaras for formal occasions. Unlike many items she wore, the Spencer Tiara never belonged to the royal collection β it remained Spencer family property throughout her life.
Diana also inherited several other pieces from her family, including diamond stud earrings that she would later have reset into different designs as her style evolved. These family pieces represented Diana's aristocratic heritage and provided her with meaningful connections to her ancestry as she entered the unfamiliar world of royal life.
Engagement and Wedding Jewelry: The Beginning of a Royal Collection
When Prince Charles proposed to Lady Diana in February 1981, he presented her with a choice of several rings. The one she selected β a 12-carat oval blue Ceylon sapphire surrounded by 14 round diamonds set in 18-karat white gold β would become perhaps the most famous engagement ring in history. Created by royal jeweler Garrard, the ring cost approximately Β£28,000 at the time (equivalent to about Β£120,000 or $150,000 today).
Interestingly, Diana's choice proved somewhat controversial among royal circles. Unlike most royal engagement rings, which were typically custom-made, Diana's ring was from Garrard's regular collection, meaning that anyone with sufficient funds could theoretically purchase the same design. This democratic choice perfectly foreshadowed Diana's approach to royalty β bringing accessibility and relatability to a traditionally exclusive institution.
For her wedding day on July 29, 1981, Diana complemented her David and Elizabeth Emanuel gown with the Spencer family tiara. She also wore diamond earrings borrowed from her mother, Frances Shand Kydd, and received a stunning diamond and pearl necklace as a wedding gift from the Emir of Qatar.
Official Royal Jewelry: Gifts from the Queen
Upon marrying into the royal family, Diana gained access to the vast royal collection through loans from Queen Elizabeth II. The Queen traditionally lends jewelry to female family members for their use during their time as working royals.
Among the most significant pieces Diana received was the Cambridge Lover's Knot Tiara, a pearl-dropped tiara originally commissioned by Queen Mary in 1914. The neoclassical design features 19 pearl pendants hanging from diamond lover's knots and became strongly associated with Diana despite her reportedly finding it quite heavy to wear.
The Queen also loaned Diana the Queen Mary's Art Deco Emerald Choker, which Diana famously wore as a headband during a visit to Australia in 1985, and the King Faisal of Saudi Arabia Necklace, a spectacular diamond and sapphire set that perfectly matched her engagement ring.
Diplomatic Gifts: Jewelry as International Relations
As Princess of Wales, Diana received numerous jewelry gifts during state visits and from international dignitaries. These pieces often reflected diplomatic relationships between nations and showcased the craftsmanship of their countries of origin.
The Saudi Arabian Suite stands as perhaps the most extravagant diplomatic gift. Given to Diana by Crown Prince Fahd of Saudi Arabia for her wedding, the set included a sapphire and diamond watch, earrings, bracelet, ring, and necklace, collectively valued in the millions. Diana wore these pieces frequently during the early years of her marriage.
During a state visit to Japan, Emperor Hirohito presented Diana with a magnificent pearl and diamond necklace featuring matching earrings. From the Sultan of Oman, she received an ornate diamond and sapphire necklace that she later had redesigned into a more contemporary choker style.
These diplomatic gifts represented not just personal adornments but international relationships and soft power. Diana's choices about when and how to wear these pieces often conveyed subtle diplomatic messages.
The Iconic Pieces: Stories Behind Diana's Most Famous Jewels
The Spencer Tiara: Family Heritage
The Spencer Tiara remains one of the most recognizable pieces associated with Diana. The diamond tiara, which had been in the Spencer family for generations, became Diana's signature headpiece for formal occasions. Unlike many royal tiaras, which featured floral motifs, the Spencer tiara showcased a more geometric pattern with scrolling designs and star-shaped flowers.
Diana chose to wear this family heirloom for her wedding instead of borrowing a tiara from the royal collection β a decision that symbolized her intention to maintain her identity even as she joined the House of Windsor. Throughout her royal career, she would choose this tiara for many major state occasions, including state banquets and diplomatic receptions.
After Diana's death, the Spencer Tiara returned to her family. It has been displayed in various exhibitions commemorating Diana's life and style but has not been worn publicly since her passing. The tiara reportedly belongs to Diana's brother, Charles Spencer, the 9th Earl Spencer, and remains at the family's ancestral home of Althorp.
The Sapphire Engagement Ring: A Royal Legacy Continues
Diana's sapphire engagement ring has perhaps the most fascinating journey of any piece in her collection. The 12-carat Ceylon sapphire surrounded by diamonds became instantly iconic when Diana wore it during the couple's engagement announcement in 1981.
What many don't know is that after Diana's divorce from Prince Charles in 1996, she continued to wear the ring, transforming it from a symbol of royal marriage to a token of her independent identity. Following her tragic death in 1997, the ring passed to her sons, with Prince Harry initially selecting it from her personal collection.
In a touching gesture of brotherly love, Harry later gave the ring to Prince William when he decided to propose to Catherine Middleton. William has said he wanted his mother to be part of his engagement in some way, and passing the ring to Catherine allowed Diana's legacy to continue into the next generation of royals.
Today, the ring β now valued at over $400,000 β remains on Catherine's finger, having gained even more historical significance as a symbol of continuity between two women who never had the chance to meet.
The Cambridge Lover's Knot Tiara: From Mary to Diana to Catherine
The Cambridge Lover's Knot Tiara represents one of the most significant pieces Diana borrowed from the royal collection. Commissioned by Queen Mary in 1914 from the House of Garrard, the tiara was modeled after one owned by Mary's grandmother, Princess Augusta of Hesse-Kassel, the Duchess of Cambridge.
The stunning piece features 19 baroque pearl pendants suspended from diamond lover's knots. Despite its beauty, Diana reportedly found it quite heavy and uncomfortable, even getting headaches from wearing it for extended periods. Nevertheless, she paired it with numerous formal gowns throughout the 1980s, making it one of her most photographed pieces.
After Diana's divorce, the tiara returned to the royal collection. It wasn't seen publicly for many years until 2015, when Catherine, Duchess of Cambridge, wore it to a diplomatic reception at Buckingham Palace. Since then, Catherine has worn the tiara several times, creating a poignant visual connection to her late mother-in-law.
The Pearl Choker with Sapphire Clasp: Royal Reimagination
Among Diana's most distinctive pieces was her seven-strand pearl choker with a massive sapphire and diamond clasp. The centerpiece of this necklace β the large oval sapphire surrounded by diamonds β was originally a brooch given to Diana as a wedding present from Queen Elizabeth The Queen Mother.
In a move that demonstrated her innovative style, Diana had the brooch converted into a clasp for a multi-strand pearl choker in the early 1980s. The transformation perfectly showcased Diana's approach to royal jewelry β respecting tradition while reimagining pieces to suit her contemporary taste.
Diana frequently paired this choker with sapphire earrings, creating cohesive looks that became her signature. The piece was particularly prominent during her visit to the White House in 1985, where she famously danced with John Travolta while wearing the choker with her "Travolta dress" β a midnight blue velvet gown by Victor Edelstein.
The Saudi Sapphire Suite: Diplomatic Treasures
Among the most valuable jewelry gifts Diana received was the Saudi Sapphire Suite, presented by Crown Prince Fahd of Saudi Arabia as a wedding present. The extensive set included a sapphire and diamond pendant with matching earrings, ring, bracelet, and watch, all designed to complement her engagement ring.
Diana frequently wore pieces from this collection during the early years of her marriage, often mixing and matching components to create different looks. The versatility of these pieces allowed her to create various combinations for different occasions.
Perhaps most famously, Diana wore the sapphire pendant on a simple chain during her dance with John Travolta at the White House. Later, in one of her style evolutions, she had the sapphire pendant reset as the centerpiece of a choker strung with seven strands of pearls.
The Emerald Choker: From Royal Loan to Iconic Headband
The Art Deco emerald and diamond choker that Diana famously wore as an impromptu headband during a gala in Melbourne in 1985 was actually a loan from Queen Elizabeth II. The piece, made from an emerald and diamond necklace that was a wedding gift to Queen Mary in 1911, had been reset as a choker for Queen Elizabeth.
The story goes that Diana was getting ready for the event when she tried to put the choker over her head instead of around her neck. When it got stuck, rather than removing it, she decided to wear it as a headband β an impulsive choice that became one of her most memorable jewelry moments.
This creative repurposing perfectly captured Diana's playful approach to royal tradition. What began as a potential wardrobe malfunction transformed into a fashion statement that only enhanced her reputation as a style innovator.
The Aquamarine Ring: Symbol of New Beginnings
Following her divorce from Prince Charles in 1996, Diana commissioned a stunning aquamarine cocktail ring that would become symbolic of her new independence. The enormous emerald-cut aquamarine, flanked by small solitaire diamonds and set in 24-carat yellow gold, was created by Asprey London.
Diana wore this ring to several high-profile events during the last year of her life, including a visit to Sydney in 1996 and to the Christie's auction of her dresses in 1997. The vibrant blue-green stone represented a fresh start and new chapter in her life.
After Diana's death, the ring was inherited by Prince Harry, who gave it to Meghan Markle to wear as her "something blue" on their wedding day in 2018. Meghan wore the ring to their evening reception, creating another touching connection between past and present royal generations.
The Value: Beyond Price Tags
Financial Worth: The Multimillion-Dollar Collection
Estimating the total value of Diana's jewelry collection presents challenges, as many pieces have both significant material value and immeasurable historical importance. However, experts have attempted to value several key pieces:
- The Spencer Tiara: Estimated at Β£400,000 to Β£600,000 ($500,000 to $750,000)
- Sapphire Engagement Ring: Originally Β£28,000 in 1981, now valued at upwards of Β£300,000 ($400,000)
- Cambridge Lover's Knot Tiara: Estimated at Β£1-2 million ($1.25-2.5 million)
- Saudi Sapphire Suite: Collective value estimated at over Β£1.5 million ($2 million)
- Pearl and Sapphire Choker: Approximately Β£800,000 ($1 million)
- Emerald Choker: Estimated at Β£10-15 million ($12-18 million)
- Aquamarine Ring: Valued at approximately Β£75,000 ($100,000)
Collectively, Diana's personal jewelry collection has been estimated to be worth between Β£20-30 million ($25-37 million) at current market values. However, the historical significance and provenance of these pieces would likely command significant premiums at auction, potentially doubling or tripling these estimates.
Historical Significance: Jewels as Historical Artifacts
Beyond their monetary value, Diana's jewelry pieces represent significant historical artifacts that document changing royal traditions and Diana's own evolution as a public figure. Each piece tells a story about a particular moment in recent British history and global cultural shifts.
For instance, Diana's preference for wearing the Spencer family tiara rather than exclusively royal pieces reflected her desire to maintain connections to her own heritage even as she embraced her royal role. Her later choices to redesign and reimagine traditional pieces demonstrated her increasingly confident personal style and willingness to break from convention.
The journey of her engagement ring β from controversial off-the-shelf selection to beloved family heirloom now worn by Catherine β encapsulates the changing nature of the monarchy itself, becoming more relatable while maintaining traditions.
Emotional Value: Personal Significance to the Royal Family
For Princes William and Harry, their mother's jewelry collection represents one of their most tangible connections to her memory. The decision about how to divide these pieces and when to incorporate them into their own family milestones clearly carries deep emotional significance.
Prince William's choice to propose to Catherine with Diana's sapphire ring was his way of including his mother in this pivotal life moment. As he explained during their engagement interview, "It's my mother's engagement ring, so I thought it was quite nice because obviously she's not going to be around to share any of the fun and excitement of it all β this was my way of keeping her sort of close to it all."
Similarly, Prince Harry incorporated Diana's aquamarine ring and diamonds from her collection into Meghan's engagement ring. These choices reflect the princes' desire to honor their mother's memory and create continuity between past and present generations of the royal family.
The Legacy: Where Are Diana's Jewels Now?
Division Between William and Harry: Personal Inheritance
Following Diana's death in 1997, her jewelry collection was inherited by her sons according to her will. While the exact division hasn't been publicly disclosed, both princes received meaningful pieces to eventually give to their future wives.
According to reports, Prince Harry initially chose the sapphire engagement ring from his mother's collection, while William selected her gold Cartier Tank watch. However, when William decided to propose to Catherine, Harry generously offered to exchange items so his brother could give Diana's ring to his future bride.
The brothers' willingness to share these precious mementos demonstrates the deep emotional connection they feel to their mother's memory and their desire to honor her legacy through their own marriages.
Catherine, Duchess of Cambridge: Wearing Diana's Legacy
Catherine, Duchess of Cambridge, has been entrusted with several significant pieces from Diana's collection. Most notably, she wears the sapphire engagement ring daily β a constant visible link between the current and previous generations.
On formal occasions, Catherine has worn the Cambridge Lover's Knot Tiara multiple times, beginning with a diplomatic reception in 2015. She has also been seen wearing Diana's triple-strand pearl bracelet, sapphire and diamond earrings, and three-strand pearl choker on various official engagements.
