0.96 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One transparent 0.96 carat oval blue sapphire, dimensions 6.42 by 4.68 by 3.66 mm, mixed brilliant cut, clarity graded as slightly included at eye level, intense color intensity, excellent polish. The cut combines a faceted crown and pavilion that maximize return of light for its size while preserving depth of color, and the oval outline provides a classic balance between face up presence and wearability. Heat treatment has been applied, a common and stable enhancement used to optimize tone and saturation, and the gem is identified as originating in Ceylon Sri Lanka. In hand the stone displays clean facet junctions and even polish, and the slightly included clarity is consistent with natural features visible only with careful examination at eye level, offering a transparent appearance and reliable durability for use in fine jewelry.

Under varied lighting this sapphire presents distinct but predictable behavior that reflects its cut, clarity, and intense color. In bright natural daylight the stone shows its truest blue, with a deep, saturated body color and lively internal reflections that emphasize the mixed brilliant facets. Direct sunlight will accentuate contrast and scintillation, producing crisp flashes from the crown facets, while diffused daylight softens contrast and highlights the evenness of tone across the table. Warm incandescent or candlelight shifts perception slightly toward a richer, more velvety blue, reducing harsh contrast and emphasizing depth. Cool white LED or fluorescent illumination can increase apparent brilliance and reveal more of the pavilion reflections, producing a vibrant, slightly cooler blue appearance. Because of the excellent polish and thoughtful cut proportions, the stone resists windowing at common viewing distances, maintaining visual saturation while offering attractive scintillation during movement. When set in a well proportioned mount that allows light entry through the pavilion, the sapphire will balance brilliance and depth effectively, and subtle differences between metal colors can modestly influence perceived intensity. The Natural Sapphire Company provides this gem with full technical description and imaging to assist in selection and setting, and to ensure that the presentation of optical behavior under different lighting scenarios matches client expectations.
