2.17 Ct. Green Sapphire from Ceylon (Sri Lanka)

This transparent green sapphire weighs 2.17 carats and is presented in a classic oval shape, with precise dimensions of 8.52 by 6.81 by 4.62 millimeters, proportions that yield a depth of about 60 percent, a balance that enhances both face up color and light return. The stone is cut as a mixed brilliant, combining a modified brilliant crown with a calibrated pavilion, a faceting approach that prioritizes scintillation while preserving color saturation in darker tones. The clarity is graded slightly included at eye level, indicating small natural inclusions that do not compromise durability, and the polish is excellent, producing crisp facet junctions and strong mirror like facet reflections. Color is of dark intensity, a deep forest green characteristic of fine Ceylon material, and the sapphire is unenhanced, a fully natural gem from Ceylon Sri Lanka, accompanied by the provenance and quality standards you expect from The Natural Sapphire Company. Optically this corundum exhibits the expected refractive index of approximately 1.762 to 1.770, a birefringence of about 0.008 to 0.010, and a specific gravity around 3.95 to 4.03, parameters that contribute to its lively brilliance and stable visual depth.

In terms of durability this sapphire benefits from the inherent physical properties of corundum, with a Mohs hardness of nine, exceptional resistance to abrasion, and reliable toughness that make it eminently suitable for daily wear in all jewelry types. The mixed brilliant cut and the proportional depth reduce susceptibility to edge chipping by maintaining a robust girdle and well distributed facet geometry, and the excellent polish minimizes surface wear over time. For everyday use we recommend secure settings such as a four or six prong design for rings or a bezel for high activity wearers, and routine cleaning with warm water and mild detergent plus a soft brush will preserve the stone’s luster. The combination of natural, untreated origin, precise cutting, and classic oval dimensions yields a practical and elegant gem ideal for engagement rings, daily wear pendants, or tailored bespoke pieces, a statement of enduring quality and provenance from The Natural Sapphire Company.
