1.14 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 1.14 carat and is presented in an emerald cut shape, with dimensions of 6.28 by 5.16 by 3.59 mm. Originating from Ceylon Sri Lanka, the stone displays an intense color intensity that is characteristic of high quality Ceylon material, with a lively blue that combines depth and clarity. Evaluated at eye level the sapphire is graded as eye clean, indicating that inclusions if present are not visible without magnification, and the surface exhibits an excellent polish that contributes to a smooth, reflective finish. The Natural Sapphire Company has documented the stone as heat treated, a standard and stable enhancement in sapphire trade, applied to optimize hue and saturation while preserving structural integrity. The overall presentation is restrained and precise, focusing on empirical attributes such as weight, dimensions, provenance, clarity, and finish, rather than speculative descriptions of value or suitability.

The emerald cut plays a decisive role in defining the optical behavior of this sapphire, with its linear step facets and broad rectangular table shaping the interaction of light within the crystal. Step cutting emphasizes large facet planes arranged in parallel, producing controlled reflections and an internal play of light often described as a clarity driven luster. For this sapphire the emerald cut enhances the apparent depth of color by allowing light to travel laterally across the pavilion planes before returning through the table, which reinforces saturation and reduces dispersion that would otherwise break the color into spectral flashes. The effect is not one of scintillation as seen in brilliant cuts, but of measured flashes and a mirror like flash along the facet junctions, which brings clarity and color into focus. The broad table allows a clear view into the stone, affirming the eye clean assessment, while the stepped crown and pavilion create a sequence of reflective planes that deliver an elegant, architectural appearance. Excellent polish ensures these planes act as efficient reflectors, minimizing surface scattering and maintaining crisp facet junctions, which is essential for maximizing the emerald cut’s intended optical character.

From a proportion and face up performance perspective the measurements of 6.28 by 5.16 by 3.59 mm correspond to balanced spread and depth, producing a pleasing table to depth relationship that supports even light return and visual weight. The relatively shallow to moderate depth typical of well executed emerald cuts enables the 1.14 carat weight to present with a generous face up area, making the color read strongly without appearing overly dark. In practical terms the cut distributes the mass so that the blue appears consistent across the table, reducing the risk of color zoning or windowing that can occur with less controlled faceting. The applied heat treatment is a common, recognized practice for sapphires, employed to intensify blue tones and to improve uniformity of color, without altering the crystal lattice in a way that compromises the stone’s durability. When combined with the stone’s Ceylon origin the result is a sapphire that retains the geological signature of Sri Lankan material, namely a bright, clear blue with lively undertones, while the emerald cut accentuates those regional attributes through its planar reflection pattern.

Suitability for mounting and care considerations stem directly from the sapphire’s cut and finish. The emerald cut’s straight edges and step facets tend to concentrate polish wear along facet junctions over time, therefore a setting that offers protective bezel or secure prong placement is advisable to preserve the facet edges. The stone’s eye clean clarity and excellent polish make it well suited for settings where the table is visible and unobstructed, including solitaire or three stone arrangements, where the controlled reflection pattern can be appreciated. The Natural Sapphire Company maintains detailed records and quality control for each sapphire we offer, documenting the origin identification, treatment history, and visual grading at eye level, which supports transparent decision making for purchasers and setters. In summary this 1.14 carat Ceylon blue sapphire in an emerald cut is characterized by intense color, excellent polish, and an optical presentation that favors clarity and color saturation over brilliance, with the step cut creating a refined, mirror like interplay of light that highlights the inherent qualities of the material.
