1.09 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes a single, natural Ceylon sapphire, weighing 1.09 carats, presented in a pear shape with dimensions of 8.83 by 5.19 by 3.18 millimeters, offered by The Natural Sapphire Company. The gem is transparent, with a clarity grade reported as very slightly included when examined at eye level, a medium color intensity, and an excellent polish. The cutting style is a mixed brilliant cut, and the stone has received no enhancement, preserving its natural color and internal characteristics. The origin from Ceylon Sri Lanka contributes to the color profile and optical character, and the combination of those attributes results in a stone that balances lively saturation with good clarity and surface finish.

The mixed brilliant cut, executed in a pear outline, is a central factor in how this sapphire interacts with light, and the faceting layout has been chosen to emphasize both brilliance and scintillation. The pear silhouette creates a variable spread of light across the table and crown, while the mixed brilliant arrangement places smaller, angular facets on the crown and a complementary pavilion faceting scheme that directs light back through the crown. This geometry promotes efficient internal reflection, enabling incident light to be captured by the pavilion facets and returned as bright white reflections and dispersed flashes. The tapered point of the pear shape acts as a focal area that concentrates light and provides directional sparkle, and the rounded shoulder and balanced length to width ratio help maintain even light distribution across the surface. The facet junctions and transitions have been finished to an excellent polish, improving the sharpness of reflected highlights, and the careful alignment of facets minimizes leakage, allowing more light to be returned to the viewer, which enhances perceived brilliance and liveliness.

The sapphire’s clarity and color work in tandem with the cut to define its visual presence. Very slight inclusions are not readily apparent at normal viewing distance, they do not interrupt the overall light path significantly, and they can even serve to subtly diffuse light, adding character without diminishing brightness. The medium color intensity provides enough saturation to convey a clear blue identity while remaining open enough for the mixed brilliant faceting to show both intense flashes and broad field reflections. The natural Ceylon hue often leans toward a cool, vivid blue, and because this specimen is unenhanced, the color is intrinsic to the stone’s formation. Excellent polish is evident in the crispness of the highlights and in the even way light returns from each facet, and that finish supports the cut geometry by reducing surface scattering. For practical considerations, the proportions and durable corundum hardness make this pear shaped mixed brilliant sapphire well suited to settings where directional light is beneficial, including rings and pendants, and the pointed end should be securely protected by a prong or bezel to maintain the stone’s symmetry and maximize its optical return. This detailed combination of cut, clarity, color, and polish is representative of the standards upheld by The Natural Sapphire Company.
