1.16 Ct. Yellowish Green Sapphire from Ceylon (Sri Lanka)

This 1.16 carat trillion shape yellowish green sapphire presents a disciplined marriage of geometry and optical performance. The trillion cut is executed as a triangular brilliant style, with a carefully proportioned crown and pavilion relationship that maximizes light return while preserving hue. At dimensions of 5.29 x 7.09 x 4.21 mm the stone sits within the ideal depth plane for a trillion, producing strong scintillation from both crown facets and pavilion mirrors. The clarity grade is very slightly included, evaluated at eye level, which in practice yields a clean face up appearance with inclusions that do not interrupt the gemature light pattern. The polish is excellent, creating uninterrupted facet junctions that allow sharp facet reflections and crisp windowing where light exits the stone. Because this sapphire is not enhanced, its surface and internal characteristics are natural, and the interplay between facet architecture and intrinsic crystal color is entirely original.

Coloration is medium light in intensity with a yellowish green tone that is characteristic of well formed corundum from Ceylon, Sri Lanka. The medium light saturation affords versatility in mounting and styling, responding differently to metal temperatures and illumination. In warmer yellow gold settings the yellow component becomes more pronounced, while in cooler platinum or white gold the green undertone reads more dominant, offering sophisticated variability that collectors value. Optical properties inherent to corundum, including a refractive index around 1.76 to 1.77 and notable birefringence, contribute to a lively appearance even at this modest carat weight. The stone exhibits balanced symmetry and consistent pavilion angling which together reduce light leakage and enhance perceived brightness. The Ceylon origin contributes to its market desirability, as Sri Lankan sapphires are historically prized for their combination of clarity and lively color, and this specimen is accompanied by certification attesting to its natural, unenhanced state and geographic provenance.

When crafted into jewelry this yellowish green trillion sapphire becomes an heirloom by design and by material. As corundum it has a Mohs hardness of 9, providing exceptional resistance to abrasion and surface wear and making it suitable for daily wear in rings, pendants, and cufflinks without compromising long term integrity. The untreated nature of the stone ensures stability in color and value over generations, while the excellent polish and well executed facet geometry mean future reconditioning requires only routine care or professional repolishing rather than corrective treatment. Provenance documentation and certification that accompany the piece increase traceability and provenance, critical qualities that collectors and family estates look for when selecting a gem to pass down. Bespoke settings that protect the three apex points, such as slightly raised prongs with reinforced shoulders or a partial bezel to shield the corners, will preserve the edge integrity while allowing light to animate the triangular table.

At The Natural Sapphire Company we recommend thoughtful mounting choices that emphasize both aesthetics and longevity, for example a low profile three prong solitaire for minimal obstruction of light or a halo setting that adds protective metal and visual weight for a central heirloom piece. The modest dimensions and 1.16 carat weight make this trillion sapphire ideally suited as a distinctive center stone for a signature ring, an accent for a classic three stone design, or a luxurious pendant intended to be worn and remembered. Coupled with the stones unenhanced origin, excellent polish, precise cut proportions, and Sri Lankan provenance, this yellowish green trillion sapphire is not only a technically accomplished gemstone but a durable and traceable centerpiece that can be entrusted to future generations.
