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

One beautiful translucent 34.36 carat oval shape white moonstone, dimensions 30.92 x 19.59 x 8.07 mm, cabochon cut, near colorless body tone, eye clean clarity as evaluated at eye level, excellent polish, no enhancement, origin Ceylon Sri Lanka. The stone displays classical adularescence produced by light scattering between intergrown feldspar lamellae, an optical effect intensified by the cabochon profile and dome height. The substantial thickness of 8.07 mm provides an ample convex surface to develop a broad, mobile sheen that reads as a soft moonlit flash, while the elongated oval silhouette offers directional control of the adularescence for design considerations. Surface finish meets exacting standards with a mirror like polish that maximizes contrast between the translucent body and the internal schiller, removing any disruption that might diffuse the sheen. The combination of near colorless body and translucent diffusion yields a clean, cool aesthetic that translates well into both contemporary and classical settings.

Cutting and selection were executed with technical precision to preserve natural optical behavior and structural integrity. The cabochon was oriented to align the feldspar lamellar planes parallel to the table, a deliberate choice that optimizes the appearance of the lunar sheen across the widest axis of the oval. Symmetry of outline and evenness of dome curvature were controlled to tight tolerances, ensuring balanced light return and an even adularescent band when viewed under directional illumination. Eye clean clarity confirms the absence of macroscopic inclusions at normal viewing distances, though the feldspar intergrowths responsible for adularescence remain the defining internal feature. Gemological parameters typical for moonstone include a refractive index range near 1.518 to 1.526, and a specific gravity around 2.56 to 2.62, characteristics that informed the cutting and polishing approach to avoid stress induced fractures. The Natural Gemstone Company presents this moonstone untreated, allowing collectors to appreciate its intrinsic optical phenomena without the influence of heat, coating, or other enhancements.

Provenance and ethical sourcing are integral to the value proposition of this gem, and The Natural Gemstone Company documents the Ceylon origin through a traceable supply chain. The moonstone was sourced from responsibly managed artisanal mines in Sri Lanka, operations that adhere to low impact extraction techniques, community centered employment practices, and reclamation protocols that reduce environmental disturbance. Purchases support verified livelihoods at the mine level, with our procurement practices favoring transparency, fair pricing, and chain of custody documentation. For the conscientious buyer this moonstone is suitable as a focal piece in an ethically curated collection, a candidate for an heirloom quality pendant or bezel set ring that protects the stone while showcasing its sheen. Practical care notes for integration into wear include awareness of moonstone hardness near Mohs 6 to 6.5, and avoidance of ultrasonic and steam cleaning to preserve internal structure, with recommended maintenance using warm soapy water and a soft cloth. High resolution images, viewing videos, and independent gemological reporting are available on request, enabling confident acquisition decisions for collectors who prioritize both material excellence and responsible provenance.
