1.15 Ct. Bluish Green Sapphire from Nigeria

This 1.15 carat bluish green sapphire from Nigeria is presented in a classical emerald cut, with dimensions 6.02 by 4.70 by 3.82 millimeters, and a length to width ratio of approximately 1.28. The emerald cut here employs broad step facets on both the crown and pavilion, producing parallel facet planes that emphasize hue and saturation rather than scintillation. The large, open table and well proportioned step facets create a controlled light return that manifests as deep, even color across the table, while the truncated corners preserve structural stability and reduce the risk of chipping at mounting. The pavilion depth yields a total depth of approximately 71 percent relative to the average of the length and width, a proportion that enhances color intensity by limiting light leakage through the base, while maintaining pleasing face up brightness for this color profile. Facet junctions are sharp, and symmetry is consistent with traditional step cut geometry, creating the hall of mirrors effect prized in high quality emerald cuts.

Optically this sapphire displays an intense color intensity, a bluish green balance that shifts subtly with viewing angle and light source, offering a teal leaning in cooler light and a richer green in warmer illumination. The clarity grade is very slightly included, evaluated at eye level, indicating fine internal features that are visible under close inspection but do not interrupt the clean, even color field or compromise durability. These minor inclusions contribute to a natural identity without detracting from the gemological integrity, and the stone remains visually strong in most wearable settings. The polish is graded excellent, with smoothly executed facet planes and minimal surface graining, resulting in crisp reflections and consistent luster. Importantly, this sapphire is reported with no enhancement, preserving its natural lattice characteristics and unaltered trace element presentation, and its Nigerian provenance speaks to a geologic environment capable of producing saturated teal to bluish green corundum due to specific iron and titanium concentrations.

From a design and wearability perspective this sapphire is highly versatile, equally suited to refined everyday jewelry and elevated formal pieces. The emerald cut silhouette lends itself to classic solitaire rings and understated pendant settings for casual elegance, where the step facets present a sophisticated, architectural look, and it can also anchor more elaborate halo or three stone arrangements for formal occasions, where the intense color will remain the focal point without excessive dispersion. For daily wear settings, a bezel or four corner prong design will protect the truncated corners while showcasing the table and step facet pattern, and for evening jewels a delicate micro prong or halo will amplify perceived size while preserving the gem as the design center. At The Natural Sapphire Company we select stones with attention to optical balance, cut precision, and natural provenance, and this Nigerian emerald cut sapphire exemplifies that approach, offering collectors and designers a gem with technical refinement, natural saturation, and practical adaptability for both casual and formal creations.
