The Dazzling Heart: A 10.47 Carat Fancy Vivid Blue Diamond

Unveiling a Gemological Masterpiece

The star of the Le Collier Bleu de Rêve is an utterly spectacular 10.47 carat blue diamond. This remarkable gemstone embodies the pinnacle of rarity and beauty, classified as Fancy Vivid Blue—the most intense and sought-after color grade for blue diamonds.

Its purity reaches an Internally Flawless (IF) level, signifying an almost absolute absence of inclusions, even under 10x magnification. Such a combination of size, color, and clarity positions this diamond among the world’s most exceptional treasures.

  • Carat Weight: 10.47 carats
  • Color Grade: Fancy Vivid Blue
  • Clarity: Internally Flawless (IF)
  • Shape: Pear-shaped

The Artistry of the “Briolette” Drop-Shaped Cut

To fully unleash the diamond’s inherent brilliance and fire, Graff meticulously chose the “Briolette” drop-shaped cut. This historic cutting method, evolving from the 17th-century rose cut, is renowned for its numerous facets that completely envelop the gemstone, allowing light to refract and reflect from every angle.

The Briolette cut is particularly suited for pendants and dangling elements, as it maximizes scintillation and visual impact as the gem moves. It ensures that the blue diamond’s captivating allure is presented with unparalleled radiance.

Exquisite Craftsmanship and Surrounding Embellishments

The Vibrant Colombian Emerald Focal Point

Complementing the magnificent blue diamond at the pendant’s center is a striking 4.22 carat Colombian emerald. This emerald boasts a vivid, bright green hue, a testament to its natural beauty and quality.

Crucially, this emerald remains entirely untreated, a highly valued characteristic that underscores its authentic and pristine nature within the world of high jewelry. Its presence adds a sublime contrast and depth to the piece.

  • Carat Weight: 4.22 carats
  • Origin: Colombia
  • Treatment: Untreated (No Heat)
  • Setting: Star-shaped central inlay

Diamond Accents and the Unique Collar Style

The intricate pendant design showcases a unique “Collar style,” providing a sophisticated framework for the central gems. This captivating setting is adorned with an array of meticulously selected white diamonds.

These accent diamonds feature a combination of pear, marquise, and brilliant cuts, each chosen to enhance the overall sparkle and elaborate artistry of the piece. Together, these elements form a harmonious composition that perfectly frames the majestic blue diamond and rich green emerald.
