1.33 Ct. Moonstone from Madagascar

This rainbow moonstone weighs 1.33 carats, it is semi transparent, and it has an emerald cut shape that measures 7.59 by 5.59 by 4.35 millimeters. The cut is precise and proportional, with well defined step facets that emphasize linear symmetry and directional light return. The specimen is graded very slightly included at eye level, it presents a medium light body color, and it has an excellent polish that enhances its surface luster. There are no enhancements, and the material is natural, sourced from Madagascar. The Natural Gemstone Company presents this stone with clear documentation of origin and treatment status, and the unenhanced state ensures that the optical effects are intrinsic to the material and the cutting work.

The emerald cut has been executed to maximize the play of light typical of high grade rainbow moonstone, the step facets and broad table channel internal light in a controlled fashion, producing a focused adularescence that shifts with movement and lighting. The stone exhibits a luminous banding that interacts with the semi transparent body, producing flashes and a subtle iridescent spectrum. The measured proportions, with a balanced length to width ratio and a moderate depth, preserve weight while allowing effective light interaction. The excellent polish reduces surface diffusion and preserves crisp facet junctions, which improves contrast between the internal sheen and the surrounding body, resulting in a clarity of effect that makes the stone visually striking rather than diffuse.

Clarity is described as very slightly included at eye level, which in practical terms means that inclusions are minimal and do not interrupt the overall optical performance when the stone is viewed in standard conditions. These minor natural characteristics are consistent with natural moonstone and can add to the gemological authenticity of the material, without detracting from aesthetic appeal. The medium light color intensity provides a neutral base that complements the internal adularescence, allowing the rainbow tones to become the focal point. From a setting perspective, the combination of semi transparency, precise emerald cut, and excellent polish makes this stone particularly suited to use as a central element in rings, pendants, and collector specimens, where controlled light exposure will best display the internal sheen.

Care and handling recommendations reflect the material properties of moonstone, which has a moderate hardness and benefits from protective mounting if used in rings or bracelets. Avoid exposure to abrasive cleaners and hard impacts, and use a soft cloth and mild soapy water for routine cleaning, with care to avoid prolonged immersion in harsh solutions. The provenance from Madagascar is noted for producing material with strong adularescent qualities, and the lack of enhancement confirms that the visual effects are inherent to the crystal structure and the cutting. The Natural Gemstone Company provides this emerald cut rainbow moonstone as a documented, unenhanced specimen, highlighting its exceptional cut and brilliance, making it a centerpiece in any collection.
