2.51 Ct. Bluish Green Sapphire from Madagascar

This transparent 2.51 carat emerald cut bluish green sapphire measures 7.69 x 7.08 x 4.55 mm, and presents the architectural clarity and controlled light return typical of a classic step cut. The emerald cut, composed of parallel rows of broad, rectangular facets on the crown and pavilion, produces large reflective planes that emphasize hue and tone rather than scintillation, and this piece displays vivid color intensity with a balanced bluish green saturation that remains consistent through the depth of the stone. The cutting proportions preserve optical depth, the table offers a clean window into the gem, and the excellent polish ensures that facet junctions are crisp and reflective, producing unbroken planes of color. Heat treatment has been applied to optimize the color, a standard enhancement that stabilizes the vivid saturation, and this sapphire is of Madagascar origin, a source known for gemstones that combine lively color with fine crystalline structure. The clarity grade is very slightly included, evaluated at eye level, indicating minimal internal features that do not compromise the gem full transparency or its suitability for high end jewelry.

The internal inclusions present in this sapphire act as natural identifiers, each inclusion serving as a microscopic fingerprint that links the stone to its geological history. Minute silk like needles and isolated pinpoint crystals are visible only under careful examination, and these inclusions create subtle silk veiling and delicate internal reflections that enrich the visual texture of the gem without clouding its color. In addition to silk and pinpoints, there may be faint growth zoning and tiny feather like features, all of which are typical of natural sapphires and useful for gemological provenance when combined with origin data. Because the inclusions are very slight at eye level, they add character and individuality, they assist in distinguishing this natural sapphire from synthetic or heavily treated material, and they provide points of reference for future identification and appraisal.

From a craftsmanship perspective, this sapphire demonstrates precise facet alignment and thoughtful facet sizing to suit the emerald cut geometry, maximizing color delivery while maintaining strong structural integrity. The durable corundum matrix, combined with the shallow pavilion depth relative to width and the robust corner truncations of the emerald cut, yields a stone well suited for rings and pendants that require both secure setting and visual presence. For discerning buyers who value technical refinement and traceable origin, The Natural Sapphire Company offers this Madagascar sapphire with full disclosure of treatment and grading, and we invite serious collectors and jewelers to request detailed photographic and gemological documentation to accompany the purchase.
