2.52 Ct. Pink Sapphire from Ceylon (Sri Lanka)

This transparent pink sapphire weighs 2.52 carats, and is presented in a round shape with dimensions measuring 8.51 by 8.44 by 4.41 millimeters. The gem has been fashioned with a mixed brilliant cut, and it carries a clarity grade described as very very slightly included evaluated at eye level. Color intensity is very light, and the surface finish is recorded as excellent polish. The stone has undergone routine heat treatment to enhance its optical characteristics, and its geological origin is Ceylon Sri Lanka. The Natural Sapphire Company documents these particulars to provide a clear and precise account of the gem, including the approximate depth proportion which calculates to roughly 52 percent. These attributes form the basis for understanding how the cut interacts with the material properties of corundum to determine the visual performance of the sapphire.

The mixed brilliant cut applied to this round sapphire is deliberately designed to reconcile two complementary objectives, brightness and color presentation, by combining a brilliant facet arrangement on the crown with a controlled pavilion geometry. Crown facets optimized for light entry and refraction allow incident light to be distributed across the crown surface, creating an overall field of brightness. The pavilion facets are proportioned to return that light through the crown in a manner that maximizes internal reflection and controlled contrast. In practical terms, the cut directs light into the gem, permits multiple internal reflections within the high refractive index medium of corundum, and then guides a large proportion of that light back to the observer. Given corundum s refractive index, which is substantially lower than diamond but sufficient to produce attractive brilliance, facet orientation and angles take on primary importance. The mixed brilliant approach emphasizes a balanced crown height and a pavilion depth that together reduce light leakage, and thereby sustain both scintillation and an even return of light across the face of the stone.

The interaction between cut and the sapphire s inherent color and clarity is central to its visual character. This example has a very light pink hue typical of many Ceylon sapphires, and the mixed brilliant proportions are selected to prevent undue darkening while still allowing for lively brightness. With a depth in the region of 52 percent, the pavilion is neither so shallow as to permit excessive light escape nor so deep as to overly concentrate light and mute the delicate tone. The very very slightly included clarity grade evaluated at eye level indicates that inclusions are minimal and located such that they do not materially interrupt the principal light paths. As a result, internal reflections remain coherent and the cut can produce consistent flashes of light rather than blotchy areas of deadness. The heat treatment applied to this sapphire is a standard and stable enhancement that improves both color uniformity and transparency, thereby complementing the cut by supplying a clearer medium for the controlled passage and return of light.

Surface finish and symmetry complete the optical equation for this stone. An excellent polish ensures that specular reflection at the facet surfaces is sharp and undulled, which maintains crisp facet junctions and enhances the apparent contrast between light and dark facets that underpins scintillation. Consistent symmetry across the round form fosters uniform distribution of light and coherent sparkle as the gem or the viewing angle changes. The dimensions of 8.51 by 8.44 by 4.41 millimeters make this gem suitable for a variety of mounting styles, and the cut s balance of brightness and color allows for versatility in settings, with prong mounts permitting maximum light exposure and bezel treatments providing protection while diminishing some light entry. This Ceylon origin sapphire, with its mixed brilliant cut, very light pink tone, very very slightly included clarity, excellent polish, and heat treatment, is presented with full disclosure by The Natural Sapphire Company to enable an informed assessment of how the cut amplifies the stone s inherent optical strengths.
