2.35 Ct. White Cabochon Moonstone from Ceylon (Sri Lanka)

This translucent white moonstone weighs 2.35 carat, and measures 12.64 by 5.82 by 4.39 mm in an elegant oval outline, presented as a traditional cabochon to maximize optical performance. The gem is near colorless in tone and carries a clarity grade of slightly included when evaluated at eye level. The polish is excellent, and there has been no enhancement applied to alter its natural appearance. Origin is Ceylon Sri Lanka, a classic source for fine feldspar material, and the combination of cut, finish, and material quality yields a refined, soft presence suitable for a range of settings that favor a gently luminous centerpiece. The Natural Gemstone Company offers this stone as a study in subtlety, with physical dimensions and optical character that allow for precise planning when setting or mounting.

The most distinctive aspect of this moonstone is the suite of internal features that create its unmistakable signature, and these inclusions are integral to its visual identity rather than detracting from it. Primary among these are thin, parallel lamellar structures aligned with the crystallographic growth of the feldspar, producing the classic adularescent sheen that appears as a bluish white band when light intersects the stone. Interspersed with these lamellae are delicate, needlelike and filamentary inclusions that register as linear streaks under oblique lighting, and as soft, oriented veils when viewed face up. A scattering of microscopic platelets and wispy cloudlike patches contribute to a layered internal landscape, breaking and diffusing transmitted light in a way that enhances the gem body and intensifies the sliding band of light that is the hallmark of moonstone.

Viewed under magnification, the inclusions present a coherent pattern of growth related features, rather than random fractures or large disruptive cavities. These growth related features are responsible for controlled light scattering, and they generate a tactile three dimensionality within the cabochon. In daylight the band of light traverses the dome smoothly, revealing subtle shifts in intensity as the stone moves, and in more directional artificial illumination the internal platelets and filaments cast fine highlights that emphasize the stone profile. Because the inclusions are modest and organized, the stone maintains a clean appearance at normal viewing distances, while offering complexity and depth to a gemologist or an attentive observer. The slightly included clarity grade reflects this balance, indicating that inclusions are present and contribute character, without overwhelming transparency or overall visual appeal.

For practical considerations when incorporating this moonstone into a finished piece, the cabochon form and consistent polish help preserve the integrity of the adularescent effect while presenting a stable mounting face. The oval proportions and the 12.64 by 5.82 by 4.39 mm dimensions are conducive to bezel, bar, or custom prong settings that support the dome and protect the perimeter from wear. The absence of enhancements ensures predictable behavior under routine cleaning and normal wear, and provenance from Ceylon Sri Lanka provides contextual information on geological formation and typical inclusion types. The Natural Gemstone Company documents these characteristics to assist designers and clients in making informed choices, and this moonstone stands as an example of how naturally occurring internal structures can define the visual signature of a gem in a way that is both identifiable and aesthetically restrained.
