1.79 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent, Other certified yellow sapphire from Ceylon is presented by The Natural Sapphire Company with careful attention to its measured qualities. The stone weighs 1.79 carats and is cut in a classic emerald shape, with dimensions of 7.58 by 5.62 by 4.06 millimeters. Its color is described as medium intense yellow, a hue that remains lively across different lighting conditions while maintaining clarity of tone. The clarity grade is slightly included when evaluated at eye level, and the gem has been given an excellent polish, yielding crisp facet junctions and a clean table face. There has been no enhancement applied, a factor that preserves the stone as a natural, untreated example of Sri Lankan sapphire material, and that context informs how its internal features are interpreted and appreciated.

The emerald cut, with its broad step facets and open pavilion, presents the internal structure of this sapphire in a way that is both revealing and architecturally elegant. Instead of dispersing light into small scintillation, the step cutting produces broad flashes and linear reflections, which serve to emphasize the stone s internal inclusions and growth features. Within the pavilion and near the culet, delicate needle like lines are visible, forming soft, parallel arrays that interact with the step facets to produce a subtle silk like sheen. Scattered among these linear features are minute reflective crystals and pinpoint inclusions that catch the light and create tiny stars of brilliance against the pale golden bodycolor. In places where growth zoning is present, faint banding and slight shifts in saturation run parallel to the step lines, adding a topographic quality to the interior that reads as a distinct signature when the stone is examined face up or in profile.

The particular suite of inclusions observed in this sapphire contributes to an unmistakable internal character, one that aligns with expectations for Ceylon origin and for an untreated specimen. The needle like silk and the presence of tiny isolated crystals produce a textural interplay that is difficult to replicate through heat treatment without altering the overall appearance of the stone. Two phase inclusions and small negative crystal cavities, where present, add depth to the interior vistas and refract light differently from the adjacent crystal fabric, creating localized flashes and subtle color shifts. Very fine healing fissures and fingerprint like clouds, when observed under magnification, demonstrate natural crystal growth and subsequent minor stress events, rather than features introduced by man made processes. Taken together these elements form an internal landscape that functions as the sapphire s natural fingerprint, a reliable visual record of its growth history in the metamorphic environment of Sri Lanka.

From a practical perspective, the visible inclusions and the open step cut invite design choices that showcase the stone s natural beauty while acknowledging its personality. The emerald cut s broad table allows the internal features to be appreciated directly, making the gem particularly suitable for settings that present the table unobstructed, such as solitaire rings or minimalist pendants with an open gallery. The slightly included clarity grade does not compromise durability, and the excellent polish ensures that light flows across the facets smoothly, accentuating both the gem s warm yellow tone and the structural character of its inclusions. As with all natural gems offered by The Natural Sapphire Company, this sapphire comes with documentation of its attributes and origin, allowing a purchaser to value not only its color and cut, but the unique natural signature that defines its provenance and individuality.
