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

This translucent 2.62 carat white moonstone, presented by The Natural Gemstone Company, is an oval cabochon with precise dimensions of 12.12 x 7.07 x 4.06 mm, a near colorless body tone, and a clarity grade of very very slightly included evaluated at eye level. The stone displays classic adularescence, a soft white sheen that travels beneath the surface as the viewing angle changes, and its translucency allows for an evocative inner glow while retaining enough body for dependable mounting. The cutter has preserved natural lamellar structure to maximize the internal light scattering that produces the sheen, and the piece has undergone no enhancement, ensuring that the optical effects, color intensity, and internal character are entirely natural and stable. The polish meets an excellent rating, yielding a smooth surface finish that allows the adularescence to resolve cleanly against the near colorless body, and the origin is Ceylon Sri Lanka, a provenance known for producing moonstones with well defined schiller and clean surfaces.

From a lapidary perspective this cabochon is a study in intentional form and proportion, the oval outline selected to centralize the adularescent band and to create a balanced visual axis when set in jewelry. The dome height of 4.06 mm relative to the 12.12 length and 7.07 width provides a medium to medium high dome, a geometry that favors a broad, diffuse sheen rather than a narrow pinpoint flash, and this proportioning is ideal for wearable applications where the optical effect should remain visible at varied angles of incidence. During cutting, the stone was oriented to exploit the feldspar layering typical of moonstone, aligning the lamellae parallel to the dome surface so that incident light can be scattered coherently. The cabochon finish was produced through staged abrasives and a final polish that eliminates microabrasions, the result being an undisturbed surface that transmits the internal schiller without surface scattering, and the symmetrical oval outline contributes to uniform light play across the table.

Optical and structural characteristics bear directly on both aesthetic and performance considerations, the adularescence arising from microscopic lamellar intergrowths of orthoclase and albite which produce coherent scattering in the visible spectrum. The near colorless intensity of this specimen means that the sheen reads as pure white rather than colored, an attribute prized for classic white moonstone aesthetics and for compatibility with a broad range of metal choices. Clarity assessed as very very slightly included at eye level indicates that inclusions are minimal and are not intrusive to the adularescent effect, and the stone maintains pleasing translucency without clouding. Measured properties for potassium feldspar group moonstones typically include refractive indices in the range of approximately 1.518 to 1.526 and a specific gravity around 2.56 to 2.62, values consistent with the material of this cabochon, and because this piece has received no enhancement its optical and physical parameters are unaltered by heating, dyeing, or oiling.

For daily wear the structural and mechanical factors must be considered, moonstone registers 6 to 6.5 on the Mohs scale of hardness which places it below many of the traditional jewelry gem materials but sufficient for everyday use when set thoughtfully. The crystal habit includes cleavage in two directions which can produce weakness if the stone receives a sharp impact at the cleavage plane, therefore we recommend bezel settings or protective rubover mounts that shield the girdle and edges while dispersing mechanical stress. Ring applications are practical when the moonstone is seated low and surrounded by a bezel or protective side gallery, and pendants, earrings, and bracelets are inherently lower risk placements for open profile settings. Routine care should avoid ultrasonic cleaners and steam, and cleaners containing acids or strong alkalis, warm soapy water and a soft brush are the safest cleaning method. Avoid knocking the stone against hard surfaces and store it separately from harder gems to prevent abrasion, and periodic inspection by a qualified jeweler will ensure bezel integrity and that the mount continues to protect the stone during daily wear. This white moonstone from The Natural Gemstone Company combines considered lapidary technique, natural optical phenomena, and a stable, polished surface, making it an excellent choice for designers and collectors seeking a wearable gem with refined adularescence and natural provenance.
