3.93 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 3.93 carat oval blue sapphire from Ceylon Sri Lanka is precisely presented with dimensions of 11.16 x 7.64 x 5.82 mm, a mixed brilliant cut, and an excellent polish. The mixed brilliant faceting combines a faceted brilliant crown with a modified pavilion faceting strategy, producing lively crown scintillation while preserving robust face up color saturation. Clarity grade very very slightly included evaluated at eye level indicates only minor internal features that do not disrupt light flow or visual appeal under typical viewing conditions. The medium color intensity is balanced across the table and crown facets, with heat treated enhancement applied to optimize hue uniformity without obscuring the stone s natural characteristics. The Natural Sapphire Company provides this gem with full disclosure of origin and enhancement, and the stone exhibits the classic optical parameters of corundum, including a high refractive index that contributes to strong light return, and a distinctive pleochroic character that allows subtle shifts between blue and violet tones as the viewing angle changes.

From a craftsmanship perspective the cutter s choices are evident in the pavilion depth and facet geometry, which are calibrated to the stone s proportions to maximize brilliance and control windowing, while the excellent polish preserves crisp facet junctions and sharp facet reflections. The mixed brilliant approach yields an appealing balance of sparkle and color, ideal for settings that showcase the table and crown, such as solitaire rings or halo mounted pendants. Over the years this sapphire will continue to captivate due to sapphire s exceptional hardness of nine on the Mohs scale, its resistance to wear, and the stability of heat treatment when performed to standard gemological practice. The very very slightly included clarity means routine cleaning and occasional professional inspection will maintain surface luster, and the underlying corundum structure resists chemical and environmental degradation, ensuring that the deep yet medium saturated blue will remain pleasing to the eye. As presented by The Natural Sapphire Company this 3.93 carat Ceylon sapphire is a technically refined and enduring stone, engineered through thoughtful faceting and finishing to deliver lasting brilliance, color integrity, and visual appeal for generations.
