0.28 Ct. Blue Sapphire from Thailand

This transparent 0.28 carat oval blue sapphire measures 4.40 by 3.30 by 2.21 millimeters and exhibits a mixed brilliant cut that marries a faceted brilliant crown with complementary pavilion cutting. The crown facets have been arranged to maximize scintillation and return through the table, while the pavilion design moderates light leakage to reinforce body color. The gem is graded included at eye level, with natural internal features that contribute to character without overwhelming light performance. Color intensity is described as intense, a saturated blue that remains vivid despite the gem small size, and polish has been evaluated as excellent, producing crisp facet junctions and lively surface reflections. Enhancement by controlled heat treatment has been applied to stabilize and intensify hue, a standard practice that enhances saturation and clarity, and the sapphire is of Thai origin, a source known for a wide range of attractive blue tones. The oval outline and careful cutting proportions allow the pavilion depth to preserve color while the relatively modest table retains concentrated flashes of lighter blue, making the stone versatile for both open back and slightly closed settings.

In jewelry this sapphire will read as distinctly vibrant due to the combination of intense tone and mixed brilliant facet architecture, it will stand out when set in white metals that emphasize contrast, or in yellow metals that warm the apparent hue, and the oval shape offers a pleasing directional presence on a finger or pendant. A four prong head or minimal bezel will expose the crown for maximum light interaction, while a halo or pavillon of white diamonds will accentuate perceived saturation by creating high contrast around the gem. For designers who favor clean, technical aesthetics, the excellent polish and precise facet mapping ensure predictable light return and consistent face up color across viewing angles, and for bespoke work the piece responds well to micro setting or simple solitaire mounting that allows light to enter through the pavilion. The Natural Sapphire Company stands behind the gemological evaluation and offers guidance on mounting choices that preserve the sapphire integrity and showcase its intense blue, ensuring the gem achieves maximum visual impact in any refined jewelry setting.
