3.58 Ct. Orangish Yellow Sapphire from Ceylon (Sri Lanka)

This 3.58 carat oval shape orangish yellow sapphire measures 10.52 by 8.41 by 5.00 millimeters, and is presented with a faceted, mixed brilliant cutting style. The gem displays an intense color intensity that reads uniformly face up, complemented by a very very slightly included clarity grade when evaluated at eye level, and an excellent polish across all facets. Origin is Ceylon, Sri Lanka, and the stone has been heat treated in a conventional and stable manner to optimize color and transparency. The combination of weight, dimensions, color saturation, and finish yields a significant face up presence, and the precise proportions maximize visual impact while retaining the natural character associated with Ceylon sapphires as represented by The Natural Sapphire Company.

The mixed brilliant cut employed for this sapphire is central to how the gem interacts with light. This cutting approach integrates brilliant style facets with carefully proportioned pavilion geometry to produce strong light return, balanced scintillation, and an even distribution of color. The cutter oriented the pavilion and crown axes to take advantage of sapphire s optical properties, using facet angles that favor total internal reflection within the stone s refractive index range, while avoiding excessive light leakage through shallow or steep zones. The length to width ratio of approximately 1.25 and an overall depth of approximately fifty three percent create a lively face up spread that promotes both bright, concentrated flashes of light and soft, uniform color. The oval outline also helps distribute brilliance across the table, and thoughtful facet placement minimizes the typical central darkening sometimes seen as a bow tie in elongated shapes, resulting in a clean, consistent visual field that accentuates the orangish yellow hue without sacrificing brightness.

Fine polish and high clarity work in concert with the cut to enhance optical performance. With clarity assessed as very very slightly included at eye level, the stone transmits light with minimal scattering from internal features, allowing facet-to-facet reflection to remain crisp and lively. The excellent polish reduces surface scattering and enhances mirror like facet junctions, so each facet plane contributes to coherent light return rather than diffuse glare. Heat treatment has been applied to stabilize and intensify color, a commonly accepted enhancement for sapphire, and this treatment, together with the precision mixed brilliant cutting, results in vivid color saturation while preserving transparency. In practical terms, the gem s cutting and finish produce noticeable brilliance and scintillation when viewed in varied lighting environments, and the measured proportions yield a pleasing balance between color depth and table light. The Natural Sapphire Company documents origin and treatment status as part of our quality standards, and this sapphire exemplifies a considered balance of natural material qualities and cutting precision, intended to perform well in a variety of settings while remaining true to the stone s inherent optical potential.
