1.00 Ct. Greenish Blue Sapphire from Nigeria

This transparent 1.00 carat asscher octagon shape greenish blue sapphire is presented by The Natural Sapphire Company. The asscher cut emphasizes geometric faceting, producing a disciplined array of step facets that form a precise octagonal silhouette. Broad, square facets on the crown and pavilion create layered planes that interact with incident light, producing crisp reflections and a focused internal luminosity. The dark color intensity gives the stone a deep, saturated tone, and the transparent body allows the faceting architecture to govern the light performance rather than masking it with opacity.

Measured at 5.57 x 4.61 x 3.90 mm, this sapphire carries an eye clean clarity grade evaluated at eye level, which ensures that the faceting patterns are visible without obstruction. The asscher cut, with its concentric step facets and a restrained, high table, channels light in controlled flashes rather than dispersed scintillation, which results in pronounced clarity of facet edges and a chiseled visual structure. Polish is excellent, preserving sharp facet junctions and allowing strong mirror like reflections from each plane. There is no enhancement, and the natural origin is Nigeria, which contributes to the gemological interest of the stone and affirms its untreated status.

For settings that benefit from architectural form, this asscher octagon sapphire performs well in designs that emphasize symmetry and precision, such as bezel and four prong mounts that reveal the octagonal outline and crown geometry. The combination of a one carat weight, step faceting, and eye clean clarity makes the gem well suited to styles that value clarity of form and depth of color. Technical documentation is available upon request, and The Natural Sapphire Company can provide additional images and viewing angles to demonstrate how the geometric faceting maximizes light play in situ.
