2.48 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing presents a beautiful translucent 2.48 carat marquise shape blue flash moonstone, measuring 15.15 by 5.82 by 3.89 millimeters, cut en cabochon to maximize its adularescence. Clarity has been graded as very very slightly included at eye level, indicating that inclusions are minimal and do not materially affect the gem's visual appeal or structural integrity, and polish has been evaluated as excellent. The body color is described as light in intensity, which is the most desirable canvas for a strong blue flash, and this stone shows a vivid, well-centered blue sheen when oriented to the light. No enhancements have been applied, the origin is Ceylon, Sri Lanka, and for cataloging and descriptive purposes the opal type is noted as White Opal to indicate its light, opalescent body color and comparable visual character within opalescent gem groupings. The cabochon marquise shape is a deliberate choice to display the adularescence over a larger surface, providing a visually striking elongated silhouette that is flattering in a variety of jewelry designs. As presented by The Natural Gemstone Company, this piece combines precise cutting, thoughtful proportions, and natural optical phenomena to appeal to collectors and connoisseurs who value authentic, unenhanced gemstones.

From a durability and daily wear perspective this moonstone performs well when set with appropriate design considerations, and several key material properties inform those recommendations. Moonstone is a variety of feldspar with a Mohs hardness typically around 6 to 6.5, which places it below harder gemstones like sapphires and diamonds but certainly within the range suitable for many types of wearable jewelry when care is applied. The crystal structure displays perfect cleavage in two directions, meaning that impact along certain planes can cause splitting, so protective mounting is important. The cabochon cut used here reduces the exposure of edges and corners that are more vulnerable to knocks, and the marquise outline, when set in a bezel or a protective prong and halo design, distributes stress and shields the stone. Because this particular gem is unenhanced and carries very minimal inclusions, there are fewer internal stress concentrators that could compromise toughness, but the inherent cleavage requires users to avoid hard impacts and abrasive contact. Routine care should include removing jewelry during vigorous physical activity, avoiding ultrasonic and steam cleaners, and using warm soapy water and a soft brush for cleaning, followed by gentle drying. For everyday wear, we recommend bezel or partial bezel settings for rings, secure settings for bracelets, and more open settings such as drops or studs for earrings and pendants where accidental knocks are less likely.

For an educated buyer, the value proposition of this moonstone is multifaceted, combining visual quality, provenance, physical characteristics, and responsible offering. The blue flash, accentuated by the skillful cabochon polish and the light body color, is the primary visual attribute that commands interest, and this specimen displays that effect clearly and attractively. Sri Lankan or Ceylon moonstones are well regarded for their clean material and pronounced adularescence, resulting from the fine lamellar intergrowths of orthoclase and albite that scatter light into the characteristic blue sheen, and origin can be an important factor for collectors who track provenance and regional gemology. The 2.48 carat weight and the generous 15.15 by 5.82 millimeter face size make this stone an excellent candidate for a statement ring, a distinctive pendant, or a bespoke pair of earrings, and the marquise outline lends itself to elegant settings that emphasize length and symmetry. Because no treatment has been applied, and because polish and clarity are high, the stone will present consistently under normal wear and will not require special disclosure regarding enhancements. The Natural Gemstone Company stands behind the natural origin, the quality grading, and the accurate description of this gem, and we encourage clients to request any additional documentation or gemological verification they require, to discuss ideal mounting options for daily wear, or to commission a custom setting that balances protection and aesthetic impact.
