3.15 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This transparent oval shaped purplish blue sapphire weighs 3.15 carats, and measures 10.64 by 8.71 by 3.63 millimeters. The stone is faceted with a mixed brilliant cutting style, and it originates from Ceylon, Sri Lanka. The color presents as an intense purplish blue, distributed evenly across the table and facets. The clarity grade is very slightly included, evaluated at eye level, and the surface condition is described as excellent polish. No enhancement has been applied to this sapphire, preserving its natural character and optical integrity, and this specimen is offered by The Natural Sapphire Company.

The gem cutter employed a geometric faceting strategy that combines brilliant cut elements with precise step facets to maximize light play. The mixed brilliant layout places a carefully proportioned table and crown angles that promote strong internal reflection, while the pavilion geometry uses a network of facets arranged to return light through the crown. Symmetry and facet alignment are executed to tight tolerances, which increases the uniformity of flash and scintillation across the oval face. The oval outline itself contributes to a continuous flow of light, minimizing dark areas and creating a lively balance between brilliance and color saturation. With this cutting approach the sapphire exhibits lively facet contrast, crisp flashes on movement, and sustained light return under varied viewing angles.

Optically the sapphire benefits from the high refractive properties of corundum, which enhance brilliance and fire relative to many other gem species. The intense purplish blue hue is complemented by the mixed brilliant faceting, which allows both full color saturation and distinct jewel tone highlights to emerge as light interacts with the stone. Pleochroic tendencies are moderated by the cut, so color remains appealing from multiple orientations, and the very slight inclusions do not interrupt light passage in any significant way. The excellent polish ensures minimal surface diffusion of light, so facet junctions remain sharp and specular, increasing apparent sparkle. Because the stone is untreated, the relationship between cut and natural color is direct, and the cutter s choices were made to enhance the innate chroma and tone rather than to compensate for any enhancement.

From a practical perspective this sapphire s proportions and geometric faceting make it versatile for a range of jewelry applications, including solitaire and halo ring designs or pendant settings where light can reach the pavilion. The oval format elongates the visual profile on a finger, while the mixed brilliant faceting maintains lively scintillation during movement. The measured dimensions allow experienced setters to plan secure, low profile bezels or prong settings that protect the girdle while exposing the crown to ambient light. When evaluating this stone, viewing under both diffused and direct light sources will best demonstrate the controlled interplay of facet reflection and body color, and the absence of enhancement means that its appearance will remain stable over time. The Natural Sapphire Company provides this description to assist in technical assessment and design planning, reflecting the stone s measured attributes and the intended emphasis on geometric faceting that yields maximum light play.
