Product specifications for this single translucent blue flash moonstone, offered by The Natural Gemstone Company, are precise and fully documented, weight 3.04 carat, shape oval, dimensions 9.72 by 7.58 by 5.67 mm, cut cabochon, clarity grade very slightly included as evaluated at eye level, color intensity medium light, polish excellent, enhancement none, origin Madagascar, opal type White Opal for reference to body tone and visual comparison. The piece exhibits classic blue adularescence commonly described as a blue flash, the phenomenon produced by oriented lamellar intergrowths of albite within the orthoclase host, the microstructure responsible for the scattering and interference of light that creates the floating sheen. Translucency is preserved across the body of the stone, allowing the adularescent band to appear distinct against a soft, milky body color that aligns with the White Opal designation in terms of body tone, while remaining materially a moonstone of the feldspar group.
Optical and material remarks address the interaction between cut and internal structure, adularescence being directional and strongest when the cabochon dome is oriented perpendicular to the schiller planes, the present cabochon height of 5.67 mm supporting a well developed blue flash when viewed along the table. The medium light body color moderates internal scattering, permitting a sharper, more saturated blue sheen without overwhelming translucency, this balance is a desirable quality for collectors seeking a distinct blue flash in a moderately sized stone. Inclusions are minor and confined, described as very slightly included at 10X equivalent observation and deemed negligible at normal viewing distances, these slight internal features do not disrupt the continuity of the adularescent band, rather they can act as internal markers of natural origin and contribute to the stone provenance narrative.
Cutting and finishing commentary focuses on lapidary technique and suitability for secure settings, the oval cabochon is proportionally balanced with a length to width ratio near 1.28, a ratio that facilitates elegant finger ergonomics in rings and a pleasing silhouette in pendants. The dome has been executed to maximize the adularescent effect, the curvature is even and the transition to the girdle is smooth, polish quality is excellent producing minimal surface diffusion and high specular reflectance, this allows the blue flash to remain vivid even under lower ambient lighting. No enhancements have been applied, the surface shows no indication of coating, dye, impregnation, or heat treatment, this natural state is consistent with responsible sourcing practices for Madagascar feldspar material and aligns with expectations from discerning buyers who prioritize authenticity and untreated specimens.
Application and styling guidance addresses versatility across casual and formal contexts, the moderate 3.04 carat weight and restrained oval profile make this moonstone adaptable for everyday wear in bezel set rings or pendant pieces that require unobtrusive comfort, conversely the pronounced blue adularescence and excellent polish provide sufficient visual impact for evening wear and formal jewellery assemblies. In cool metal palettes such as sterling silver or white gold, the blue flash is visually reinforced creating a serene, lunar aesthetic, while warmer settings in yellow or rose gold produce a high contrast presentation that emphasizes body color and internal depth, both treatment paths are valid depending on the design intent. The Natural Gemstone Company stands behind the documented specifications including origin Madagascar and no enhancement, and recommends routine care that avoids prolonged exposure to harsh chemicals and extreme heat, cleaning with mild soap and a soft brush is effective, ultrasonic and steam cleaners should be avoided to preserve lamellar integrity and the natural adularescent phenomenon.
