3.08 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This GIA certified cushion shape blue sapphire weighs 3.08 carats, and measures 8.62 millimeters by 7.41 millimeters by 5.40 millimeters, translating to a depth percent of approximately 67.4 percent, a geometry that preserves body color while promoting lively return of light. The cutting style is a mixed brilliant cut, combining a brilliant facet arrangement on the crown with modified step faceting on the pavilion, a deliberate design choice to balance scintillation and color saturation. The stone exhibits vivid color intensity in the deep blue spectrum, and a clarity grade described as very slightly included when evaluated at eye level, meaning that the internal characteristics are minor, do not impede overall transparency, and contribute to the gemological signature without distracting from visual performance. The polish is graded excellent, the stone is transparent, and standard industry enhancement by heat treatment has been applied and documented on the GIA report, confirming the treatment stability under normal wearing conditions. Chemical and physical properties inherent to corundum, including a refractive index in the range of 1.762 to 1.770, a specific gravity near 3.99 to 4.00, and a low dispersion value, govern the way this sapphire renders deep tone and blue flashes, while pleochroic behavior is controlled by the cutter to present a consistent, uniform face up color.

From a lapidary standpoint the cutter has executed a precise pavilion architecture to avoid windowing and to maximize the interaction between the stone internal color zones and incident light. The mixed brilliant crown uses small to medium sized star and kite facets to generate controlled scintillation, while the pavilion steps are tuned to increase color depth and optical saturation, a technique often employed when the source material shows strong chroma but requires facet engineering to avoid dead zones. The result is a stone that retains depth of hue even under varied lighting, and that distributes flashes evenly across the table and crown facets. The very slightly included clarity grade indicates inclusions that are persistent on close inspection at eye level, but the cutter has oriented the face up position to minimize their visibility, and the excellent polish further masks minor facet junction irregularities, producing crisp facet edges and high surface luster. Heat treatment, the most common and accepted enhancement for sapphire, has been applied to relieve color zoning and to homogenize chromophores, and because the treatment is permanent under normal conditions, the gem is suitable for everyday set pieces when mounted with appropriate protective settings.

When compared to famous sapphires in history this piece presents a compelling and distinct proposition rather than a mere imitation, it shares chromatic qualities associated with historically celebrated stones such as the Logan Sapphire and certain royal stones in the British collection, in that it exhibits a deep saturated blue with cool undertones that read as stately and intense. It does not attempt to replicate the specific provenance or scale of a museum piece, instead it occupies a unique place by combining vivid saturation with a wearable 3.08 carat weight that makes it far more practical for contemporary jewelry. Whereas Kashmir sapphires are often prized for a velvety cornflower blue and diffuse silk like phenomena, and Burmese sapphires are noted for intense but warmer blue tones, this Ceylon origin sapphire presents a lively, high chroma blue that benefits from Sri Lankan crystallography, yielding clarity and brightness not always present in stones of equal saturation. The Natural Sapphire Company offers this gem with full GIA documentation and origin attribution, making it an attractive choice for collectors who seek a historically resonant color profile combined with modern lapidary optimization. For connoisseurs who value technical refinement, color fidelity, and documented provenance this deep blue cushion sapphire represents a rare convergence of classical hue, precise faceting technique, and practical scale, an ideal candidate for a centerpiece engagement ring or a museum quality pendant that will perform well in both display and daily wear.
