1.06 Ct. Bluish Green Sapphire from Tanzania

This cushion shape bluish green sapphire weighs 1.06 carats and measures 6.73 by 5.42 by 3.28 millimeters. It is a transparent, mixed brilliant cut stone with a well-balanced pavilion depth of approximately 54 percent, which contributes to effective light return and a pleasing face-up appearance. The color presents a vivid intensity across the table, and the clarity is graded very slightly included when evaluated at eye level, indicating only minor internal characteristics that do not materially affect visual performance. The polish is excellent, producing clean facet junctions and crisp reflections. This sapphire is untreated, reported with no enhancement, and originates from Tanzania. The Natural Sapphire Company provides this gem with full disclosure of these attributes, offering a naturally formed example of Tanzanian coloration and cutting style.

Under natural daylight, particularly indirect northern light, the stone displays its truer bluish green hue with even saturation and lively internal brilliance, the mixed brilliant faceting creating dynamic scintillation as the gem is moved. In direct sunlight the stone reads slightly deeper and more teal, with intense contrast between the larger crown facets and the smaller brilliant facets producing bright flashes and visible depth. Under cool white fluorescent or cool LED lighting the blue component is emphasized, producing a crisp, more vivid blue-green appearance and sharper facet contrast. In warm incandescent or warm LED illumination the stone trends subtly toward the greener end of its spectrum, appearing richer and more velvety while maintaining internal sparkle due to the precise polish and facet geometry. In low or ambient indoor light overall brilliance is reduced, but the sapphire retains a strong body color and delivers a soft internal glow, particularly when set to allow light to enter through the pavilion. Because the cut balances step and brilliant elements, the stone offers both strong scintillation on movement and pleasing depth when viewed face-up, making it well suited to ring or pendant settings that expose the crown to varied light sources.
