2.53 Ct. Bluish Green Sapphire from Tanzania

This transparent bluish green sapphire weighs 2.53 carat and is cut in a classic emerald shape, with precise dimensions of 7.94 x 6.14 x 5.14 mm. The stone is of Tanzanian origin and shows intense color intensity, evaluated as very slightly included at eye level, with an excellent polish. No enhancement has been applied, preserving the natural character of the material. The emerald cut and the stone dimensions deliver a measured, elegant profile, emphasizing broad, even color planes and a depth of tone that suits both solitaire and halo settings.

The emerald cut is a step cut that favors color and clarity over scintillation, so this sapphire will present broad flashes of deep bluish green rather than lively pinpoint sparkle. In bright daylight the stone reads a cooler, cleaner blue green, with the blue component becoming more apparent under neutral to cool natural light. Under LED or cool fluorescent sources the sapphire also leans toward the bluer side of its spectrum, appearing crisp and richly saturated. Under warmer incandescent or candle light the stone shifts toward a greener, teal aspect, the depth of tone becoming more enveloping and velvety. Spot lighting, such as a focused gallery lamp or a well placed table lamp, will create strong contrast between the step facets, producing defined flashes along the pavilion and crown that accentuate the cut lines and the excellent polish. Because the gem is transparent and only very slightly included, light passes well through the stone, so the color remains consistent across viewing angles while showing subtle pleochroic tendencies depending on the light source.

For secure presentation The Natural Sapphire Company recommends settings that allow light to enter the pavilion, such as prong or open bezel galleries, to maximize the appearance of its intense color and step facet reflections. The natural, untreated origin combined with the emerald cut makes this sapphire a refined choice for those who value color integrity and a sophisticated optical presence. Routine cleaning in warm soapy water and careful handling will preserve the excellent polish and maintain the gem s performance in varied lighting conditions.
