2.12 Ct. Cabochon Moonstone from Madagascar

This listing describes a single, translucent blue flash moonstone, weighing 2.12 carats, presented in a round shape with precise dimensions of 9.13 by 9.17 by 3.55 millimeters. The stone has been fashioned as a cabochon, a cut selected to maximize adularescence and surface luster, and it exhibits a medium light color intensity with a pronounced blue flash visible under directional light. Clarity has been graded as very slightly included when evaluated at eye level, a condition that produces minimal internal features which do not detract from the overall visual impact, and the surface has been finished to an excellent polish. There has been no enhancement of any kind, the origin is Madagascar, and the specimen is provided and verified by The Natural Gemstone Company.

The combination of size, clarity, and cut makes this moonstone particularly well suited to serve as the focal element of a statement piece. At just over 9 millimeters in diameter and 2.12 carats, the gem occupies a scale that is immediately noticeable when set for wear, while remaining comfortable for ring and pendant applications, or as a prominent single stone in bespoke jewelry designs. The cabochon profile, together with the modest thickness of 3.55 millimeters, creates a balanced dome that presents a broad surface area for the blue adularescence to move and shift, producing a clear, lunar sheen across the face of the stone as the viewing angle changes. Because the clarity is described as very slightly included at eye level, the internal characteristics are sufficiently minor that they do not interrupt the primary optical display, allowing the blue flash to read cleanly across the dome and to remain the dominant visual attribute from typical viewing distances.

From a design and setting perspective, the stone’s nearly symmetrical round outline and consistent dimensions simplify translation into classic statement formats, including a solitary cocktail ring, a pendant with a minimal surround to emphasize the dome, or a single stone brooch intended to command attention. The excellent polish on the cabochon enhances light return and gives the surface a glasslike finish that complements both high polish metalwork and more textured mounting approaches, while the stone’s natural translucency contributes depth and an inner glow that is difficult to reproduce through treatment. In practice, settings that allow controlled access to light, such as a subtle open back or a low bezel that secures the girdle without obscuring the lower portion, will make the most of the adularescent effect, while secure prong placement can be used when protection of the rounded dome is a higher priority. The 3.55 millimeter depth offers adequate material for firm seatings and professional jeweler manipulation without significantly increasing weight or bulk, making the gem versatile for both contemporary and traditional statement concepts.

As a natural, untreated moonstone from Madagascar, this gem represents the characteristics buyers seek in an unenhanced specimen, including authentic adularescence, inherent translucency, and a clarity profile that supports a refined appearance rather than a commercialized, highly modified look. The Natural Gemstone Company confirms that no enhancements have been applied, ensuring the optical behavior you observe is intrinsic to the material. For customers commissioning a piece that prioritizes presence and refined optical performance, this stone provides a reliable focal point around which proportionally scaled metalwork can be designed to emphasize scale, light, and finish. Care for a moonstone of this type should focus on avoiding abrasive impacts and harsh chemicals, preserving the polish and the stone’s surface integrity, and routine inspections of the mounting once set will maintain both the presentation and the protective security of the piece over time.
