The $500 Million Secret: 7 Shocking Facts About The 'Heart Of The Ocean' Necklace From Titanic
The "Heart of the Ocean" necklace remains one of the most recognizable and coveted pieces of jewelry in cinematic history, a deep blue symbol of tragic romance and immense wealth from James Cameron’s 1997 blockbuster, Titanic. As of December 2025, the fascination with this fictional jewel continues, driven by questions about its real-life inspiration, its staggering estimated value, and the fate of the authentic, multi-million dollar replica.
This iconic jewel—known in the film's lore as the legendary blue diamond owned by Louis XVI and cut into a heart shape—is not merely a prop; it is a cultural phenomenon that has spawned countless replicas and a genuine, high-value masterpiece that was once worn on the Academy Awards red carpet. The true story of the necklace involves a world-famous jeweler, a charity auction, and a connection to the world’s most infamous blue diamond, the Hope Diamond.
The Heart of the Ocean: Essential Specifications and Facts
While the necklace is a fictional creation, its various forms—the film prop and the real-life jewel—have distinct and fascinating specifications. This detailed profile separates the movie’s lore from the actual jewelry created by the prestigious London jeweler, Asprey & Garrard.
- Name (Film): The Heart of the Ocean (French: Le Cœur de la Mer).
- Inspiration: The legendary 45.52-carat Hope Diamond, a deep blue gem with a rumored curse.
- Fictional Carat Weight: 56 carats (a heart-shaped blue diamond).
- Jeweler (Prop & Real): Asprey & Garrard (now known as Garrard).
- Prop Composition: Cubic Zirconia set in White Gold (Edwardian-style setting).
- Prop Designer: Commissioned by Titanic Production Designer Peter Lamont.
- Real-Life Auctioned Jewel Composition: A 171-carat heart-shaped Ceylon Sapphire surrounded by 103 diamonds.
- Real-Life Auction Price (1998): $2.2 million (sold to an anonymous bidder).
- Estimated Fictional Value: If the jewel were real, its value would be an estimated $350 million to over $500 million, placing it among the most expensive fictional jewels ever conceived.
- Famous Wearer: Celine Dion wore the real Asprey & Garrard necklace to the 1998 Academy Awards.
- Current Location: At least one of the film props is currently exhibited in a museum in Cornwall.
The Shocking True Value: Prop vs. Real-Life Masterpiece
The confusion surrounding the "Heart of the Ocean" often centers on its value. There are three main versions of the necklace, each with a vastly different price tag: the movie prop, the real high-jewelry piece, and the authorized replicas.
The Movie Prop: Cubic Zirconia and White Gold
Director James Cameron confirmed that the necklace was a plot device, not based on a single real item. For the close-up shots of Rose DeWitt Bukater (played by Kate Winslet) wearing the jewel, the necklace was crafted by Asprey & Garrard using inexpensive materials. The main pendant was a large, heart-shaped cubic zirconia, a synthetic stone, set in white gold to achieve the Edwardian-style look required for the 1912 setting. This prop, while priceless to film history, has a material value of only a few thousand dollars.
The $2.2 Million Asprey & Garrard Jewel
The most famous, high-value version of the necklace was created by Asprey & Garrard for the 1998 Academy Awards. This was a genuine, stunning piece of high jewelry, not a prop. It featured a colossal 171-carat heart-shaped Ceylon Sapphire, renowned for its deep blue hue, surrounded by 103 flawless diamonds, weighing over 30 carats in total. This magnificent piece was worn by singer Celine Dion, who performed "My Heart Will Go On." It was later auctioned at a star-studded gala in Beverly Hills, fetching $2.2 million, with all proceeds donated to charity.
The Multi-Million Dollar Fictional Value
If the fictional 56-carat blue diamond from the film were a real, flawless gem of that size and color, its value today would be staggering. Experts estimate the hypothetical value of the "Heart of the Ocean" to be between $350 million and $500 million, making it one of the most expensive pieces of jewelry imaginable, comparable only to the world’s most famous historical diamonds.
Where to Find the Heart of the Ocean Today: Replicas and Collectibles
The enduring popularity of the film and its central love story between Jack Dawson and Rose has ensured a massive market for replicas, allowing fans to own a piece of the Titanic legacy. These items range from affordable costume jewelry to highly sought-after collectibles.
The J. Peterman Company Replicas
Following the film's release, the J. Peterman Company sold authorized replicas of the "Heart of the Ocean" necklace. These pieces are highly prized by collectors today and often come with a Certificate of Authenticity. These replicas, which typically feature a large Austrian Crystal or simulated blue Sapphire pendant, occasionally appear on auction sites like eBay and Propstore, sometimes selling for hundreds of dollars, demonstrating their collectible value.
Modern Replicas and Jewelry Design
The design continues to inspire modern jewelers. Today, countless replicas are available, often featuring a large blue crystal pendant, sometimes with rhodium-plated chains or set in sterling silver. The typical pendant size for a replica is around 4.2 cm to 5.5 cm in height, hanging from a 49 cm (18-20 inch) Box Chain, closely mimicking the proportions worn by Rose in the film.
The Real-Life Historical Connection
While the "Heart of the Ocean" is fictional, there is a historical link to a real jewel on board the RMS Titanic. Research suggests that a diamond and sapphire necklace may have been on the ship, hinting at a small seed of truth that inspired the fictional masterpiece. This detail only adds to the mystery and allure of the jewel, ensuring its place not just in movie history, but in the lore of famous, cursed, and iconic gems like the Hope Diamond and other famous movie jewelry such as the Isadora Diamond or The Toussaint.
