9.55 Ct. Green Sapphire from Madagascar

This transparent 9.55 carat asscher cut green sapphire presents a refined balance of size and symmetry, with dimensions 11.84 by 11.74 by 7.39 mm. The stone is fashioned in an asscher cut octagon shape that emphasizes large, concentric step facets, producing a restrained hall of mirrors effect rather than a brilliant scatter of light. Clarity is eye clean when examined at eye level, and the polish has been graded excellent, resulting in crisp facet junctions and clean reflective planes. Color intensity is vivid, and the gem has been heat treated, a common and stable enhancement that improves saturation and clarity. The material originates from Madagascar, a source known for producing a broad range of green sapphire hues. This sapphire is suitable for a substantial solitaire ring or a statement pendant where the asscher geometry can be appreciated from multiple viewing angles.

Under natural daylight the sapphire displays its most accurate hue, with cool daylight tending to reveal slightly fresher and more bluish green undertones while maintaining vivid saturation. In direct sunlight the step facets create distinct, layered flashes and strong contrast between light and dark areas, giving the gem a lively, architectural appearance. Under warm incandescent lighting the overall tone deepens, and the green reads richer and more velvety, with internal reflections taking on a warmer leaning that enhances perceived depth. Modern white LED lighting highlights facet clarity and edge definition, producing crisp flashes and an impression of higher contrast, while lower ambient lighting emphasizes the stone core, presenting a deep forest green with subtle internal movement. The asscher cut concentrates color, so the viewing angle will influence whether the eye perceives more intense color or more pronounced internal reflections, and slight pleochroic effects are possible as the stone is rotated. The Natural Sapphire Company offers this gem with full disclosure of treatment and origin, and the combination of asscher cut geometry, excellent polish, eye clean clarity, and 9.55 carat presence yields a versatile, durable piece, benefiting from sapphire hardness for everyday wear while retaining the visual depth and refined light behavior that collectors and connoisseurs value.
