1.08 Ct. Pinkish Purple Sapphire from Tanzania

This transparent 1.08 carat pear shape pinkish purple sapphire measures 7.30 x 5.49 x 3.74 mm, and is presented by The Natural Sapphire Company. The cutting style is faceted, executed as a mixed brilliant cut that combines a faceted crown with a precision pavilion to optimize internal light return. The cutter has maintained a balanced table and crown angle relationship, producing strong facet junctions and uniform facet girdle alignment, and the polish is graded excellent. Clarity is slightly included when evaluated at eye level, with sparse pinpoint and minor crystal inclusions located toward the pavilion that do not materially disrupt overall light performance. This sapphire is natural and untreated, no enhancement, and originates from Tanzania, which contributes to its distinct pinkish purple hue and structural clarity.

Optically the stone exhibits intense color intensity with a dominant pink violet saturation that reads vivid in both daylight and artificial light sources. Corundum pleochroism is evident under directional illumination, revealing subtle shifts between pink and a cooler purple, and the mixed brilliant cutting strategy enhances this effect by enabling alternating light and dark facet contrast. The crown facets disperse light into broad flashes of color rather than high dispersion fire, while the pavilion facets act to return light efficiently to the viewer, producing strong scintillation and a lively pattern appropriate to the pear silhouette. The combination of crown height and pavilion depth was optimized to reduce windowing and maintain color saturation across the girdle, resulting in consistent brilliance and an even face up appearance.

When compared to other gemstones in its category, this Tanzanian pinkish purple sapphire shows optical behavior consistent with corundum, characterized by a refractive index around 1.76 to 1.77 and low dispersion relative to gemstones such as diamond. Compared to spinel and pink tourmaline, this sapphire displays superior luster and light return due to corundum density and facet reflection, while dispersion or fire is more restrained than in high dispersion gems, which yields a cleaner, more saturated color presentation rather than spectral flashes. Against typical blue sapphires, this stone places greater emphasis on hue and pleochroic shifts because of its pink violet chroma, and its mixed brilliant cut maximizes both face up brilliance and color saturation. For collectors and designers seeking a durable, vividly colored, untreated corundum with precise cutting and excellent polish, this piece offers technical refinement and reliable optical performance.
