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

This translucent 13.60 carat oval white moonstone is precisely proportioned at 18.25 x 9.31 x 10.38 millimeters, presenting a classic cabochon profile that maximizes adularescence through a high, evenly domed crown and a well-centered girdle, the cabochon cut is executed with attention to symmetry and dome curvature to optimize the play of light inherent in orthoclase feldspar, eye clean clarity at normal viewing distance ensures the surface field appears free of internal interruptions, near colorless body tone provides a neutral canvas that enhances the subtle sheen without introducing color distractions, excellent polish across the dome and pavilion produces crisp, mirror-like reflections that indicate careful lapidary finishing, the specimen is unenhanced and originates from Ceylon Sri Lanka, natural origin and lack of treatments are documented, the oval outline and measured thickness are ideal for ring, pendant, or earring designs where the stone can display its luminous quality while maintaining a conservative profile for secure setting.

From a durability and daily wear perspective, this moonstone is well suited to jewelry with appropriate protective design, as an orthoclase feldspar it registers approximately 6 to 6.5 on the Mohs hardness scale, this affords reasonable resistance to abrasion but requires awareness of its two perfect cleavages and moderate toughness, the cabochon form reduces the likelihood of facet edge chipping and distributes impact across the dome, therefore bezel settings or closed gallery mounts are recommended for rings and bracelets, prong settings can be used for pendants and earrings where impact exposure is lower, avoid ultrasonic cleaners and steam treatments and clean with warm soapy water and a soft brush to preserve polish and optical effects, prolonged exposure to harsh chemicals or extreme heat should be avoided to prevent surface alteration, for daily wear we advise placement in protective mounts, routine inspection of the setting, and storing the gem in a soft pouch to prevent contact with harder materials, this fine example from The Natural Gemstone Company combines gemstone provenance, lapidary excellence, and practical considerations for everyday jewelry, making it a durable and visually captivating choice for discerning buyers and designers.
