0.78 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.78 carat round blue sapphire is a technically refined example of Ceylon gem cutting, with precise dimensions measuring 5.38 by 5.33 by 3.54 millimeters, yielding a depth of approximately 66.1 percent based on the provided proportions. The mixed brilliant cut combines a traditional brilliant crown with a faceted pavilion that incorporates both brilliant and modified facets to optimize light return and color saturation. The cutter has executed tight symmetry and an excellent polish, resulting in crisp facet junctions and minimal surface abrasion, which supports the gem being transparent and evaluated as eye clean at typical viewing distances. The piece has been heat treated to enhance color uniformity, a stable and widely accepted enhancement for sapphire, and it originates from Ceylon Sri Lanka, a region renowned for producing stones with lively, saturated blues.

Color performance is a defining attribute of this sapphire, described as vivid in intensity with strong, even saturation across the body of the stone. The mixed brilliant faceting strategy produces both concentrated flashes of white brilliance and broad zones of blue color, creating dynamic contrast as the stone moves under light. The relatively deep pavilion depth enhances color depth without sacrificing proportional brilliance, delivering scintillation from the crown and pleasing color return through the table. The excellent polish amplifies optical clarity, allowing the observer to appreciate the stone s internal transparency and the crisp geometry of its facets. Overall the balance between tone and saturation is consistent with high quality Ceylon material, offering a visually compelling blue that reads as vivid rather than dark or overly gray.

As a gift the combination of technical quality and visual impact makes this sapphire especially striking for a special occasion, whether as a solitaire engagement center, a refined three stone accent, or a bespoke piece designed to highlight the rounded mixed brilliant profile. Its near one carat weight and robust optical performance allow it to perform well in both open prong settings that maximize light intake and in lower bezel settings that emphasize color and durability.
