0.81 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This heart shape blue sapphire weighs 0.81 carat, and measures 5.86 x 6.08 x 3.24 mm, and presents a clear, transparent body with no enhancement. The stone is from Ceylon, Sri Lanka, and it carries an intense color intensity that is characteristic of fine Sri Lankan material. The cutting style is faceted, executed as a mixed brilliant cut, and the gem has been evaluated as eye clean at eye level, with an excellent polish. These objective specifications describe a natural, untreated sapphire in a precise, measurable way, and they form the basis for assessing its visual performance and suitability for a variety of fine jewelry settings.

The faceting geometry of this mixed brilliant heart has been planned and executed to maximize light return and internal reflection. The mixed brilliant approach pairs a modified brilliant crown with a pavilion that balances depth and facet orientation, creating a dynamic interplay of light as the stone moves. The crown facets catch incident light and refract it into the body of the gem, while the pavilion facets redirect that light back through the crown, producing sustained brilliance and scintillation. The heart outline is proportioned to preserve symmetry between the lobes and the point, ensuring that the geometric faceting patterns align across the stone. The result is a lively, even display of light, with flashes that emphasize the rich blue tone and reveal subtle variations in saturation across the gem planes.

Clarity and polish further enhance the optical performance of this sapphire. Being eye clean at standard viewing distances means there are no inclusions visible to the unaided eye that could interrupt light passage or create dark windows. The excellent polish on each facet yields crisp facet junctions and smooth planes, which allow for clean internal reflections and a high degree of contrast between light and dark areas as the gem is tilted. Combined with the intense color intensity, the gem presents a strong and consistent blue that reads as vivid under neutral lighting and displays attractive depth in daylight. The absence of enhancement preserves the stone in its natural state, and this integrity contributes to both its visual appeal and its long term stability in jewelry.

From a practical perspective the dimensions and heart shape make this sapphire versatile for a range of settings, with the 5.86 x 6.08 mm table offering a pleasing face up size for a delicate ring, a pendant, or as part of a three stone composition. The modest depth of 3.24 mm is balanced against the mixed brilliant pavilion to maintain optimum light return while allowing secure bezel or prong settings without excessive metal coverage of the crown. The heart outline is best supported by a precision setting that follows the lobes and point, preserving the silhouette and allowing light to interact with the faceting geometry unobstructed. Given the inherent durability of corundum, this natural sapphire is appropriate for day to day wear with standard care, and proper mounting will protect the point and lobes from impact while showcasing the gem to best effect.

The Natural Sapphire Company presents this sapphire with a focus on documented quality, provenance, and the gemological attributes that determine visual performance. The combination of a mixed brilliant faceting plan, eye clean clarity, excellent polish, intense Ceylon blue color, and the absence of enhancement results in a sapphire that demonstrates technical refinement and natural character. For clients and designers seeking a refined heart shape blue sapphire that emphasizes geometric faceting and maximum light play, this stone offers a clear specification set to guide mounting decisions and design direction, and it is available through The Natural Sapphire Company for examination and incorporation into bespoke or ready to wear pieces.
