3.62 Ct. Bluish Green Sapphire from Madagascar

This transparent C.Dunaigre certified bluish green sapphire weighs 3.62 carat, and presents an elegant fancy shape with dimensions of 7.98 x 10.91 x 5.70 mm. The cutting style is faceted with a precision step cut, executed to emphasize broad planar facets across the crown and pavilion. The cutter prioritized parallel facet lines and crisp facet junctions, resulting in a gem that displays controlled light return rather than the dispersed scintillation of mixed cuts. The stone exhibits intense color intensity, excellent polish, and a clarity grade assessed as very slightly included at eye level, all attributes confirmed by the C.Dunaigre certification. Heat treated to stabilize and intensify hue, this sapphire originates from Madagascar, a provenance that contributes to its crystalline structure and trace element profile.

The bluish green hue of this sapphire is both complex and durable, the result of trace element balances that favor iron and titanium contributions over chromium, giving the gem a cooler green with distinct blue tonality. The intense color grade indicates strong saturation across the stone, and the step cut enhances this saturation by presenting large, contiguous color planes that allow observers to perceive depth and consistency of tone from multiple viewing angles. Pleochroic tendencies are subtly present, producing slightly different impressions of blue and green when the stone is rotated, a characteristic that lends visual dynamism without compromising overall color stability. Heat treatment has been applied in a controlled manner to relieve internal strain and to enhance color uniformity, a conventional and permanent enhancement that improves long term wearer confidence.

Clarity and cutting precision are central to the gemological quality of this sapphire. Evaluated as very slightly included at eye level, the stone reads as clean to moderate scrutiny, with minute internal features that do not detract from transparency or brilliance. The step cut demands high clarity because its planar facets act as windows into the crystal, therefore the cutter selected an orientation that minimizes the visual impact of inclusions and maximizes optical symmetry. The excellent polish ensures sharp facet edges and smooth planes, which in turn support crisp reflections and a stable visual field. Dimensionally the stone balances weight and face up presence, offering a generous table and well measured depth that preserve optical performance while maintaining an elegant silhouette suited to a variety of mounting styles.

From a wearability and longevity perspective this sapphire is exceptionally well suited to fine jewelry, thanks to corundum hardness that registers at nine on the Mohs scale, and the structural integrity preserved by professional heat treatment and expert cutting. The step cut favors settings that allow light to enter parallel to the facet planes, making prong settings that expose the pavilion or open bezel designs desirable for maximizing color depth and lustre. For rings intended for everyday wear, a secure four or six prong mount or a partially inset bezel will protect the girdle and sustain visual impact. Routine maintenance consists of gentle ultrasonic cleaning when set in stable metals, and periodic inspection of the setting to ensure the facets and polish remain pristine. Origin from Madagascar provides traceability and a known geological context, while the C.Dunaigre certification documents the stone provenance and treatment history.

The Natural Sapphire Company presents this bluish green sapphire as an object of enduring natural beauty and technical excellence, a gem whose intense hue, precise step cutting, and excellent polish will continue to captivate over the years. Its optical character will age gracefully, with heat treatment providing stable color enhancement and the inherent toughness of corundum ensuring resilience under normal wear. Minimal internal characteristics serve as testament to natural formation rather than detractors, and the combination of craftsmanship and gem quality ensures the stone will retain its visual appeal as it becomes part of your curated collection. For connoisseurs and designers seeking a technically refined, certified Madagascar sapphire with lasting presence, this gem is a distinguished choice from The Natural Sapphire Company, and we welcome inquiries regarding certification documentation, mounting recommendations, and bespoke settings to showcase its long term beauty.
