0.61 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This transparent 0.61 carat round bi color sapphire represents a balanced meeting of measured proportions and natural character. The gem measures 5.29 millimeters by 5.28 millimeters by 3.05 millimeters, and it is cut in a mixed brilliant style that combines faceting approaches to optimize light return and color distribution. The clarity grade is very slightly included evaluated at eye level, and the gem displays an excellent polish that communicates the cutter's attention to facet symmetry and surface finish. The stone has medium light color intensity, and it is free of enhancement, indicating that no heat treatment or other modification has been applied. The origin is Ceylon Sri Lanka, a provenance noted for producing sapphires with fine color nuance and stable crystalline structure. These objective details define the gem for precise comparison and for integration into bespoke designs.

The most distinctive visual attribute of this sapphire is its bi color character, presented as two complementary hues that subtly shift when the stone is rotated or when viewing conditions change. Under direct light the stone reveals a soft interplay between a warm yellow tone and a cooler bluish gray field, creating a delicate contrast that is both restrained and expressive. With a medium light overall intensity, the colors remain readable without overpowering, allowing the stone to function well in settings that favor understated elegance. The mixed brilliant cut contributes to the gem's optical performance by balancing scintillation with broader flashes of light, and the excellent polish enhances surface luster so that the bi color effect remains crisp and pleasing to the eye. For settings, this stone performs well as a solitaire or as a focal accent in a halo design, where the interaction between metal color and the stone's two tones can be evaluated and selected to emphasize either the warmer or the cooler face of the gem.

The internal features of the sapphire are consistent with a very slightly included clarity grade evaluated at eye level, and these inclusions should be understood as natural identifiers rather than defects. Minute internal characteristics are common in natural corundum, and in this specimen they provide a set of unique markers that can be used to match the stone to documentation or to identify it under magnification. When examined closely the inclusions act as an internal fingerprint, helping gemologists and experienced jewelers confirm natural origin and continuity of condition over time. These internal features can influence the way light is transmitted and scattered within the stone, and in some orientations they contribute to the gem's overall character by adding subtle texture to the visual field. The presence of such features does not compromise the structural integrity of corundum, which is one of the hardest and most durable gem materials, yet they do contribute to the individual personality of the stone in a way that treated or laboratory produced material typically does not.

For practical considerations the stone's dimensions and mixed brilliant proportions offer reliable guidance for mounting and setting, and the relatively shallow girdle profile combined with the measured depth suggests compatibility with standard bezel or prong styles while preserving the gem's optical performance. The lack of enhancement confirms that the color and internal characteristics are wholly natural, and the Ceylon Sri Lanka origin contributes to the gemological story and to predictable performance under daily wear. Routine care involves standard practices for sapphire jewelry including gentle cleaning with warm soapy water and soft brushes, and secure mounting to minimize risk of edge or girdle chipping during handling. The Natural Sapphire Company provides full documentation for this gem, and we encourage clients to review the provided details and images to confirm suitability for their intended design. This bi color sapphire offers a measured combination of verifiable specifications, subtle color play, and natural internal character, making it an appropriate choice for those seeking a natural, unenhanced sapphire with distinctive visual personality.
