10.24 Ct. Bluish Green Sapphire from Madagascar

This C. Dunaigre certified, transparent bluish green sapphire weighs 10.24 carats and is fashioned in an emerald cut with precise dimensions of 13.19 x 10.41 x 7.60 mm. The stone presents a step cut geometry, which emphasizes clean lines and broad facet planes. Clarity has been evaluated as eye clean, evaluated at eye level, which indicates the absence of inclusions visible to the unaided eye and contributes to a calm, open appearance through the table. Color intensity is described as vivid, with an even saturation of bluish green across the pavilion and crown, and the piece exhibits an excellent polish that enhances surface luster and tactile smoothness. No enhancement has been applied, so the material is in its natural state and the reported characteristics describe what is inherent to this rough and to the cutter's decisions.

The emerald cut, or step cut, is particularly effective in presenting the sapphire's color and clarity in an elegant, restrained way, favoring broad flashes and subtle light planes rather than scintillation. In this example, the cutting proportions and excellent polish allow the vivid bluish green to present uniformly when viewed face up, and the long rectangular outline accentuates the stone's size and color distribution. Because the step cut relies on larger facets, it highlights the stone's internal clarity, so the eye clean grading is especially advantageous for both visual purity and classical optical appeal. The dimensions of 13.19 x 10.41 x 7.60 mm yield substantial surface area, providing a presence that reads larger on the finger or in a central setting, while maintaining balanced depth for secure mounting.

Origin and treatment status are fundamental components of a sapphire's identity, and this specimen is sourced from Madagascar, a region known for producing sapphires with attractive saturation and character. The C. Dunaigre certification documents the stone's measured attributes and its untreated status, adding an independent record of provenance and quality. No enhancement. Being untreated means the color and clarity are natural and stable under normal wear conditions, and there is no risk of color instability due to surface filling or heat related modifications that could alter appearance over time. With this documented background, the sapphire carries both descriptive and scientific confirmation of its material qualities, which is important for long term conservation and for collectors who prioritize natural, verifiable gemstones.

The intrinsic properties of corundum, combined with the gemological characteristics of this piece, explain how its natural beauty will continue to captivate over the years. Sapphires rate nine on the Mohs hardness scale, affording strong resistance to abrasion and preserving polish through regular wear, and the excellent polish on this stone will therefore remain reflective with basic, periodic maintenance. The vivid bluish green color in an untreated material is stable to light and temperature under normal conditions, and the step cut minimizes the appearance of small internal features while creating broad, elegant light returns that age gracefully rather than competing visually with trend driven sparkle. With appropriate setting design to protect the girdle and proper care such as gentle cleaning with warm water and a soft brush, occasional professional inspection, and mindful avoidance of hard impacts, the stone will retain its visual impact and structural integrity for generations. The Natural Sapphire Company documents and supports the gem's attributes, and the combination of verified origin, untreated status, excellent polish, and classical emerald cut ensures this sapphire will remain a distinct and enduring expression of natural beauty over time.
