0.99 Ct. Bluish Green Sapphire from Madagascar

This 0.99 carat radiant shape bluish green sapphire is an exemplary specimen for the informed buyer, presenting a clear case for both aesthetic appeal and gemological quality. The stone measures 6.16 by 5.45 by 3.08 millimeters, a dimension set that preserves face up presence while maintaining ideal proportions for light return. Its radiant cut is executed with geometric precision, combining trimmed corners and an array of step and brilliant style facets to yield a lively and controlled display of brightness. The hue reads as a balanced bluish green with an intense color intensity, and the material is transparent, allowing internal light paths to contribute to depth and saturation. Origin is Madagascar, a locale known for producing a spectrum of high quality corundum, and importantly, this sapphire has no enhancement, confirming that color and clarity are entirely natural, which is a premium attribute in the marketplace.

The faceting of this radiant sapphire is designed to maximize light play, and the gemological details explain why the effect is so successful. Radiant cuts employ a hybrid facet structure that marries the scintillation of brilliant facets with the depth and contrast of step facets, producing a combination of lively flashes and broad color zones. In this gem the pavilion and crown have been proportioned to optimize internal reflection for corundum, whose refractive index encourages strong return of light when angles are correct. The excellent polish contributes to crisp facet junctions and uninterrupted light flow, enhancing both brilliance and luster. Clarity is graded as very slightly included at eye level, which in practical terms means inclusions are minor, do not significantly impede light movement, and are typical of natural sapphire formation. For the user, this clarity grade preserves the gem's visual performance while confirming natural origin and character, as completely inclusion free sapphires are extraordinarily rare. The combination of the radiant geometry, excellent polish, and the stone being untreated creates a gem that is both visually compelling and scientifically sound.

For a buyer with an eye for long term value and wearable beauty, this Madagascar sapphire offers several compelling points. Untreated material commands a market premium because it represents unaltered geological color, and Madagascar has become an increasingly respected source for such material, providing both desirable color and responsible sourcing opportunities. The near one carat weight is versatile for settings ranging from classic solitaires to three stone arrangements, and the radiant shape offers durable corners that are practical for everyday wear. Corundum hardness of nine on the Mohs scale assures that the gem will resist scratches and maintain polish under normal use, and the excellent polish improves resistance to surface wear. From a design perspective, the bluish green tone works well with both white and yellow metals, and the intense color intensity allows the gem to read as saturated at a modest table size, which is important for visual presence in modern jewelry designs.

At The Natural Sapphire Company we assess and present gemstones with transparency and technical clarity, and this sapphire is offered with its measured specifications to assist in informed decision making. We recommend professional settings that protect the corners and exhibit the pavilion to maximize light return, and we can advise on mounting options that enhance the stone without obscuring its natural characteristics. For the collector or the client seeking a centerpiece that is both rare and wearable, the lack of enhancement, the precise radiant faceting, the very slightly included clarity at eye level, and the Madagascan origin together constitute a gem that is both scientifically verifiable and aesthetically distinctive. If you would like a formal appraisal, lab documentation, or assistance in selecting a mounting that emphasizes the geometry and light play of this sapphire, The Natural Sapphire Company can provide that support and ensure the gem is presented to its full potential.
