2.49 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.49 carat oval transparent blue sapphire presents exacting proportions, measuring 8.54 by 7.58 by 4.99 millimeters, a format that favors both strong face up color and optimal light return. Origin Ceylon Sri Lanka imbues this stone with the classical Ceylon blue character, a balance of medium tone and intense saturation described here as intense color intensity, which reads as a vivid, evenly distributed blue across the table and facets. The cutting style is faceted, executed in a mixed brilliant cut that combines brilliant facet geometry on the crown with a modified step and brilliant arrangement on the pavilion, a combination selected to maximize brilliance and return while preserving color depth. Enhancement has been carried out by heat treatment, the industry standard for sapphires from this origin, applied to stabilize and intensify the stone’s intrinsic blue, a treatment that is permanent and compatible with mounting and wear.

The mixed brilliant faceting on this oval is engineered to balance scintillation and color concentration, with a well proportioned crown height and pavilion depth that control the critical angles for total internal reflection specific to corundum optics. The crown presents a well centered table, with star facets and bezel facets cut to consistent angles to produce a steady pattern of flashes, while the pavilion mains and lower girdle facets are aligned to deliver even light return and minimize dark areas or windowing. The facet junctions exhibit symmetry within fine tolerances, and the excellent polish contributes to high surface lustre and uninterrupted light transmission, the result being crisp facet delineation and crisp contrast between bright and dark areas that animate the stone as it moves. From the girdle to the culet the execution preserves a refined outline and balanced bow tie effect typical of ovals, ensuring that the intense blue remains saturated without appearing overly dark in the corners.

Clarity is graded very slightly included evaluated at eye level, an assessment that denotes inclusions are minute and not readily noticeable without magnification, and that they do not interfere with transparency or the quality of light return. In practice this means the gem reads clean to the unaided eye across a range of viewing distances, while under loupe examination one can observe small, localized features characteristic of corundum, distributed in a way that does not distract from the stone’s overall visual performance. Those micro inclusions can in fact contribute to the gem’s character, diffusing light subtly and enhancing depth without compromising brilliance. The excellent polish and precise facet alignment minimize any scattering that could reduce sparkle, so the stone exhibits strong brilliance and lively scintillation from every viewing angle, and the mixed brilliant design enhances both the vibrant face up color and the internal play of light. At The Natural Sapphire Company we present this sapphire as an example of considered cutting and careful sourcing, a gem that combines technical precision with natural material quality, an ideal candidate for settings that benefit from pronounced color and controlled light behavior, such as four prong semi bezel or halo designs, where the craftsmanship of cutting and polish will be visible and appreciated.
