0.84 Ct. Purplish Pink Sapphire from Tanzania

This 0.84 carat oval purplish pink sapphire measures 5.78 by 4.25 by 3.65 mm and is cut in a mixed brilliant pattern. It is transparent, displays vivid color intensity, and carries a clarity grade of very slightly included, evaluated at eye level. The finish is an excellent polish and the stone is without enhancement. Origin Tanzania. The Natural Sapphire Company presents this stone with straightforward documentation of its natural characteristics and cutting quality.

The sapphire’s internal structure and the choices made in cutting and finishing together create a level of sparkle that stands apart. As a corundum, the material is a dense and optically responsive aluminum oxide crystal in a trigonal lattice. That lattice, combined with the presence of chromium trace elements that provide the purplish pink hue, yields a high refractive index and strong internal reflection. Although corundum has less dispersion than diamond, its high refractive index produces bright return of white light, while the mixed brilliant cut converts that light into crisp scintillation. The mixed pattern uses a brilliant style on the pavilion to maximize light return and lively sparkle, and a faceted crown geometry that both reinforces color saturation and provides balanced flashes. The stone’s transparency and the very slightly included clarity at eye level mean that light passes through with minimal obstruction, allowing clean facet-to-facet reflection. The excellent polish minimizes surface scattering so that more light is redirected internally and returned to the viewer as concentrated flashes and scintillation.

Together, the material properties of Tanzanian corundum, the vivid purplish pink color produced by chromium, the precise mixed brilliant cutting proportions, and the high quality polish create a dynamic interplay of color and light. The oval outline concentrates color while elongating the pattern of flashes, producing a lively but controlled brilliance. Presented by The Natural Sapphire Company, this 0.84 carat oval sapphire exemplifies how natural structure and disciplined cutting combine to deliver a sparkle that is both distinctive and technically refined.
