The Enigmatic Tiffany & Co. Blue Book Jellyfish Brooch

Unveiled as part of the esteemed 1998 Tiffany Blue Book Fine Jewelry Collection, this exquisite Jellyfish Brooch is a masterful replica that captures the ethereal beauty and fluid motion of a “Man-of-war Jellyfish” (Portuguese man-of-war). This exceptional piece combines the mystical glow of moonstones with the vibrant allure of purple sapphires, creating a truly mesmerizing work of art.

Each element of this brooch is meticulously chosen and crafted, reflecting Tiffany & Co.’s unwavering commitment to unparalleled quality and design. It stands as a testament to haute joaillerie, bringing a piece of the ocean’s wonder to life for the discerning collector.

Distinguished Materials and Specifications:

  • Precious Metals: Crafted from luxurious gold and platinum, ensuring both durability and a timeless aesthetic.
  • Cabochon-Cut Moonstones: A total weight of 22.61 carats, chosen for their captivating adularescence that perfectly mimics the jellyfish’s translucent body.
  • Baguette-Cut Sapphires: Featuring 19.33 carats of baguette-cut sapphires, adding a striking contrast and depth to the intricate design.
  • Round Brilliant-Cut Diamonds: Embellished with 2.97 carats of dazzling round brilliant-cut diamonds, providing exceptional sparkle and undeniable luxury.

A Storied Origin: The Inspiration Behind the Design

The genesis of this iconic Jellyfish Brooch traces back to a unique commission by the renowned American horticulturist and connoisseur, Mrs. Rachel “Bunny” Mellon. Following an unexpected encounter with a Portuguese man-of-war jellyfish during a serene beach stroll with her dog, Mrs. Mellon was captivated and inspired to commemorate the experience.

She promptly approached Jean Schlumberger, one of Tiffany’s most celebrated designers, with a request for a brooch that would capture the distinctive form of the creature. This fascinating personal anecdote imbues the design with a rich narrative, transforming a momentary sting into an enduring piece of jewelry history and a symbol of Schlumberger’s creative genius.

Masterful Craftsmanship: Gemstone Artistry

The Luminous Moonstone Canopy

Jean Schlumberger’s ingenious design utilizes an impressive cabochon-cut moonstone to form the jellyfish’s distinctive umbrella-shaped bell. The moonstone’s characteristic hazy luster beautifully emulates the transparent, gelatinous body of a living jellyfish, while its subtle light blue iridescence evokes the vast, mysterious depths of the ocean.

This careful selection of gemstones creates a captivating visual effect, giving the brooch a lifelike quality and an otherworldly glow that harmonizes with its natural inspiration.

Dynamic Tentacles and Striking Sapphires

Flowing gracefully beneath the moonstone canopy are the jellyfish’s delicate tentacles, meticulously rendered from slender gold tubes. These individual segments are intricately connected, allowing for a captivating, free-swinging motion that mirrors the natural sway of a jellyfish in water. This dynamic element brings a profound sense of fluidity and organic movement to the piece.

To further enhance the design and reference the creature’s notable “stingers”—a key part of Mrs. Mellon’s original inspiration—Schlumberger adorned the edges of these tentacles. While the original design featured classic baguette-cut sapphires, this exceptional replica brilliantly incorporates vivid purple sapphires. These gems provide a stunning visual contrast, their bright tones complementing the moonstone’s serene glow and adding a distinctive royal flourish to this iconic brooch.
