0.91 Ct. Yellowish Green Sapphire from Madagascar

This 0.91 carat oval yellowish green sapphire from Madagascar is presented by The Natural Sapphire Company with precise gemological detail. The stone measures 6.73 x 5.04 x 3.10 millimeters and has been cut in a mixed brilliant style to balance table brilliance with pavilion return. Clarity is graded as very slightly included when evaluated at eye level, and the gem is transparent with no enhancements. Color intensity is described as intense, and the gem has an excellent polish that contributes to clean facet junctions and consistent light return. At just under one carat the proportions and pavilion depth support a lively face up appearance while retaining a depth that secures color saturation, making the piece well suited to a variety of fine jewelry settings that benefit from both color and sparkle.

Optical performance of this sapphire is driven by the material properties of corundum and by the cutter s choices. Corundum s refractive index produces good brilliance and a strong contrast between bright facets and dark facet windows, and the mixed brilliant cut here enhances scintillation across small movements. The excellent polish maximizes facet reflectivity so that light is returned efficiently to the observer, producing crisp flashes of yellow and green rather than diffuse glow. Pleochroism in sapphires can cause subtle shifts in hue when the gem is rotated or viewed under different lighting, and this yellowish green example displays a controlled, attractive shift that adds depth without disrupting overall clarity. The very slight inclusions are not disruptive to light transmission at typical viewing distances, so the stone presents a clean, lively appearance under day to day wear.

When compared to other gemstones commonly used for green or yellow green stones, this sapphire s reflective qualities are distinct in several ways. Relative to other sapphires, such as blue or classic green variants, this gem benefits from corundum s high refractive index which yields stronger facet contrast and more assertive brightness than beryls and some tourmalines. Against peridot, which typically shows higher birefringence and can exhibit doubling and a more oil like internal sheen, the sapphire provides sharper facet reflections and a steadier color presentation. Compared with emeralds, which often have significant inclusions that disrupt light flow and reduce brilliance, the Madagascar sapphire returns light more uniformly and displays greater surface luster. Spinel in comparable tones can appear very clean and lively because of its lack of pleochroism, however spinel s slightly lower refractive index produces a softer brilliance than corundum in equivalent cuts. Finally, gemstones with notably high dispersion such as zircon or diamond display more fire than sapphire, but those materials can appear more fiery at the expense of the pure, saturated body color that characterizes this yellowish green sapphire. The result is a gem that occupies a balance between strong color saturation and dependable, focused brilliance, making it a refined choice for settings that require both color intensity and optical precision.

In summary, this transparent 0.91 carat oval yellowish green sapphire from Madagascar offers intense color, very slight eye visible inclusions, and an excellent polish in a mixed brilliant cut, characteristics that together produce measured, high quality light performance. The Natural Sapphire Company presents this stone as an example of corundum s ability to fuse vivid color with effective light return, providing a polished aesthetic that compares favorably with other green gemstones in scenarios where both color stability and reflective clarity are important. The gem s hardness and polish make it a practical option for everyday jewelry, while its optical balance ensures a lively presence without excessive fire or color instability.
