3.10 Ct. Bluish Green Sapphire from Madagascar

This cushion shaped bluish green sapphire weighs 3.10 carats, and measures 8.91 by 6.66 by 5.30 millimeters, presenting classical cushion proportions with rounded corners and a substantial pavilion depth that enhances color saturation. The gem is fashioned in a mixed brilliant cut, combining a brilliant style crown with precisely faceted pavilion steps, a configuration that maximizes both scintillation and depth of color. Cut proportions result in a depth that is approximately sixty eight percent relative to the average of the length and width, a depth range that favors intense face up color while maintaining strong light return when mounted in an open backed setting. Facet junctions are crisp and the symmetry is precise, supporting a well balanced return of white light and spectral flashes, and the polish is excellent across crown and pavilion, yielding clean facet reflections and a high degree of finish uniformity.

Color is intensely saturated bluish green, exhibiting a deep teal character that remains lively under both daylight and indoor illumination. The mixed brilliant faceting scheme has been executed to present broad color zones on the table and controlled windowing towards the pavilion, which produces a dynamic interplay between deep saturation and internal light play. Optical behavior is consistent with trace iron content contributing to blue green hues, and the stone displays distinct pleochroic response, with blue green and greener tones visible from different orientations. Clarity is graded as very very slightly included, evaluated at eye level, and the stone appears eye clean in practical wear, with the minute inclusions confined to internal crystal features that do not disrupt facet reflections or brilliance. No enhancement has been applied, this is a natural unheated sapphire, which preserves the original growth features and natural color distribution, and which is increasingly prized by connoisseurs for its purity and potential for long term rarity.

Origin from Madagascar contributes materially to this sapphire's desirability and market value, because Madagascar produces a wide spectrum of natural sapphire hues and is recognized for stones that combine strong saturation with transparent crystal quality. Malagasy sapphires are formed in high temperature metamorphic and igneous environments, often yielding well defined crystals that cut to excellent clarity and color, and the provenance signals a modern supply chain that is well documented and subject to current ethical sourcing practices. Within the collector and bespoke jewelry communities, Madagascar origin is associated with distinct color profiles and geological provenance that appeal to informed buyers, and the presence of an unheated stone from this island nation enhances both aesthetic and investment attributes. At The Natural Sapphire Company we document origin and treatment status, and we present this sapphire as a high quality natural example that benefits from both the geological character of Madagascar and the meticulous lapidary work that produced the mixed brilliant cushion.

This gem is well suited for a centerpiece ring or a bespoke pendant, where the combination of intense bluish green color, generous three carat weight, and refined mixed cut will read as both bold and refined. For secure and optimal face up presentation we recommend an open backed prong or low bezel setting to allow light to enter the pavilion, which maximizes the stone s scintillation and preserves its natural depth and color. Given its excellent polish, consistent symmetry, and eye level clarity, the stone will perform with abundant brilliance and controlled color saturation when set in white or warm metals, depending on the desired visual temperature. The Natural Sapphire Company stands behind the gem s origin and natural, untreated status, and we can provide detailed imagery and certification upon request to support appraisal, bespoke design, or investment grading.
