0.89 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.89 carat radiant shape blue sapphire measures 5.55 x 5.28 x 3.02 mm, with a measured depth of approximately 3.02 mm, yielding a moderate depth ratio of about 56 percent, which supports balanced light return in a square radiant pavilion. The radiant cut combines trimmed corners and a mixed facet scheme, with brilliant crown faceting that maximizes scintillation and a pavilion that integrates small step facets to preserve color uniformity, and the excellent polish enhances facet crispness for clean windowing and lively flashes. The stone is transparent with an included clarity grade evaluated at eye level, indicating visible internal features that are stable and consistent with natural Ceylon material, and the gem has been heat treated, a stable enhancement that has improved color saturation and clarity without altering the fundamental crystal structure. Face up the sapphire exhibits a light color intensity, a cool to slightly violet biased blue hue, and a lively surface reflection that allows the gem to read as delicate cornflower to icy blue under standard daylight, making it particularly well suited to settings that allow light access to the pavilion.

Comparatively this Sri Lankan, or Ceylon, example shows a lighter, airier blue and a more pastel tone than classic Kashmir sapphires, which are typically known for a rich, velvety cornflower blue with deeper tone and higher saturation. Against Burmese sapphires this stone reads less saturated and more transparent, Burmese material tending toward a vivid royal blue with stronger medium to dark tone. Madagascar sapphires may show a similar brightness, but often with higher saturation pockets, whereas Montana sapphires commonly present more steely or teal leaning blues that are darker and less vivid than this light Ceylon example. Australian sapphires generally appear much deeper and inky, providing a strong contrast to the luminous, light blue face up of this gem. At The Natural Sapphire Company we present this sapphire as a technical and aesthetic specimen that highlights the signature Ceylon lightness and brilliance, ideal for clients who prefer delicate, well polished blue sapphires with a crystalline transparency and a refined, cool blue hue.
