1.12 Ct. Bluish Green Sapphire from Madagascar

This transparent 1.12 carat oval bluish green sapphire measures 6.70 by 5.35 by 3.60 millimeters, it is faceted with a mixed brilliant cut, and it displays an intense color intensity with excellent polish, enhancement by heat treatment, and origin Madagascar. The mixed brilliant design pairs a brilliant style crown with a proportioned pavilion treatment to maximize light return while conserving weight in an oval outline, the measured depth of 3.60 millimeters yields a depth approximately 60 percent relative to the average diameter which sits well within the range that promotes balanced return of light through the crown, the clarity grade is very slightly included evaluated at eye level which indicates minor internal features that do not materially disrupt pavilion to table light paths, the excellent polish ensures minimal surface diffusion and crisp facet junctions so that specular reflections remain sharp under loupe and naked eye inspection. The gemstone exhibits tight facet symmetry and controlled table proportions that enhance scintillation without sacrificing the gem's saturated bluish green tone, the heat treatment stabilizes and intensifies the hue by resolving color zoning and reducing silk inclusions which in turn increases transparency and effective brilliance.

When compared to more common gemstones this sapphire offers a distinct optical profile, it differs from diamond which exhibits higher refractive index and dispersion, diamonds deliver stronger white brilliance and play of spectral fire, this sapphire with corundum refractive index approximately 1.76 to 1.77 produces less spectral fire but offers stronger colored light return and more saturated color flashes, compared to aquamarine and topaz which have lower refractive indices and generally paler tones, this sapphire stands out by combining intense color saturation with durable hardness and lively scintillation, compared to emerald which may show richer green but often at the expense of clarity, this Madagascar sapphire offers a superior balance of color, clarity, and toughness. The natural pleochroism of bluish green sapphires is optimized by the mixed brilliant facet architecture, different viewing angles reveal green and blue dominant flashes which creates a dynamic visual experience that is rare among more common gemstones, The Natural Sapphire Company presents this stone as an example of how precise cutting, controlled heat enhancement, and high polish can produce remarkable brilliance that complements and accentuates its uncommon bluish green color.
