10.89 Ct. Greenish Blue Aquamarine from Ceylon (Sri Lanka)

Aquamarine carries a lineage that reaches back to ancient seafaring cultures and classical civilizations, its name deriving from the Latin for seawater, evocative of calm horizons and vessels guided by starlight. In every era, from Roman signet rings to Georgian pendants, aquamarine has been prized for its tranquil, ocean-like hue that suggests both clarity of spirit and steadfast endurance. The greenish blue tone of this particular stone connects it to the storied mines of Ceylon, where gem cutting traditions have been passed down through generations, and where artisans shaped light with the same measured respect for form and proportion that has defined classical jewelry for centuries. At The Natural Gemstone Company, we honor that history by selecting stones that not only speak to technical excellence, but also to the timeless narratives they carry, making each gem a living link between past and present.

This remarkable, certified blue aquamarine is a 10.89 carat oval, a size that asserts presence without sacrificing elegance, with well-balanced dimensions of 16.68 by 14.17 by 7.99 millimeters. Cut in a mixed brilliant style, the pavilion faceting complements the oval silhouette, marrying the scintillation of modern cutting with the enduring grace of a classic shape. Its transparency is notable, and the clarity is graded as very slightly included when evaluated at eye level, a detail that affirms its natural origin and enhances its depth without distracting from the overall visual purity. The light color intensity bathes the stone in a soft, sea-glass radiance, a tone that feels simultaneously delicate and immediately compelling. With an excellent polish and no enhancements, this aquamarine is presented in its most honest state, allowing the natural chemistry of the crystal to perform without alteration, and ensuring the wearer experiences an authentic expression of Ceylon’s geological artistry.

In any jewelry setting, the vibrant greenish blue of this aquamarine will command attention while blending seamlessly with elegant design languages that span centuries. Set as a solitaire, its oval profile will elongate the finger and radiate a serene authority that is both modern and classically refined. Surrounded by a halo of brilliant diamonds, the stone will appear to float within a halo of fire, the mixed brilliant cut throwing playful flashes while the light color remains calm, a study in contrast that honors traditional design principles. For those who prefer heritage silhouettes, a three-stone ring or an intricately filigreed pendant will allow the gem to read as an heirloom, a piece meant to be worn and passed down. The stone’s substantial face-up size and excellent polish also lend themselves to cufflinks, brooches, and bespoke pieces where the gem becomes the centerpiece of a carefully considered composition. Its durability and stability ensure that it endures daily wear, while its color retains a unique presence whether set in cool white metals to enhance its blue notes, or in warm gold to draw out the green undertones.
