A Diamond is Forever - De Beers and Assouline Chronicle 100 Years of Cultural Brilliance

A Collector’s Tome for the One Percent

At the intersection of storytelling, elegance, and enduring legacy, Assouline and De Beers Group unveil one of 2026’s most collectible luxury books: A Diamond is Forever: The Making of a Cultural Icon 1926–2026.

Celebrating a century of cultural influence, this 240-page volume is more than a retrospective—it’s a powerful tribute to the role diamonds continue to play in the identity, love stories, and investment portfolios of the global elite.

Launching globally in Assouline boutiques and online on January 30, the publication reintroduces the legendary De Beers tagline—“A Diamond is Forever”—to a new generation of UHNW readers who view luxury jewelry not just as adornment, but as a vessel of value, symbolism, and permanence.

The Iconography of Desire

From Picasso to Marilyn Monroe, from the mid-century golden age of Hollywood to today’s digital collectors of rare high jewelry, the book captures the cultural evolution of the world’s most coveted gemstone. With advertising archives, commissioned artworks, and essays spanning 100 years, A Diamond is Forever transports the reader into the universe of De Beers: a brand that has shaped how the world sees commitment, wealth, and timeless beauty.

Among its highlights is a journey through the “Shadows” campaign of the 1990s, an avant-garde fusion of black-and-white cinematography and neoclassical music, presenting diamonds not just as luxury goods but as living symbols of eternal emotion.

Why Diamonds Still Matter in 2026

For UHNW individuals—the top 1% whose ranks have grown to over 392,000 worldwide, with collective wealth exceeding $42.4 trillion—the meaning of luxury jewelry has expanded. No longer confined to red carpet appearances or private safes, fine diamonds now represent a growing category of tangible alternative assets, prized for their portability, scarcity, and emotional resonance.

The global luxury jewelry market is projected to reach $68.3 billion by 2028, driven in part by the demand for high-craftsmanship pieces with provenance, storytelling, and artistic relevance. Books like this one, born from a partnership between Assouline and De Beers, are also physical manifestations of that market—designed not just for reading but for display, collection, and legacy building.

The Book as Investment and Testament

Priced at $195, A Diamond is Forever: The Making of a Cultural Icon is a rare cultural artifact in its own right—accessible yet elevated, modern yet historical. For UHNW collectors, this isn’t just a coffee table book. It’s a declaration of values: permanence over flash, symbolism over noise, and heritage over hype.

As family offices and private collectors expand their interest in curating not only assets but aesthetic identity, this publication enters the scene as a collectible time capsule—one that fits neatly between a Cartier Panthère, a Vacheron Constantin perpetual calendar, and a Fabergé Winter Egg.

Closing Reflection

De Beers and Assouline’s collaboration is not merely a book launch—it’s a cultural crescendo. For the 1%, it affirms that true luxury is measured not by price alone, but by narrative, permanence, and beauty that transcends generations.

The only question left is: will your library—or your legacy—be complete without it?
