9.57 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One translucent peach moonstone, 9.57 carat, oval shape, measuring 17.72 x 10.12 x 7.35 mm, is presented by The Natural Gemstone Company. The gem is fashioned as a cabochon cut with a smooth domed profile and symmetrical outline, finished to an excellent polish. Color is assessed as medium light intensity in the peach range, consistent across the surface with gentle saturation that reads well against both warm and neutral metal tones. Clarity is graded very slightly included at eye level, indicating only minor internal features that do not detract from general appearance when viewed without magnification. No enhancement has been applied, and the material is sourced from Ceylon Sri Lanka, a provenance known for producing feldspar specimens with fine translucency and stable color. Weight to size ratio falls within expected norms for moonstone cabochons, offering substantial heft while preserving an elegant elongated oval footprint.

Cutting and finishing considerations are central to the performance of this stone, and the cabochon has been executed with attention to orientation and dome geometry to optimize adularescence. The cutter has aligned the growth planes, exploiting the layered feldspar microstructure inherent to moonstone, so that incident light encounters the orthoclase and albite lamellar interfaces at favorable angles for coherent scattering. The dome height of 7.35 mm provides sufficient depth to develop a soft internal glow without sacrificing profile balance for bezel settings. Apex placement is centered along the major axis, yielding uniform light return and symmetrical flash across the oval field. Surface polish quality is excellent, producing clean specular highlights and minimal surface disruption, which preserves the subtle schiller effect typical of quality moonstone. Internal inclusions are limited to fine platelets and occasional silk like filaments that contribute to the stone character but remain subdued at normal viewing distances, consistent with the very slightly included clarity grade.

Practical considerations for jewelry fabrication and long term care are important for buyers and designers. The 17.72 by 10.12 mm dimensions permit a range of mounting options, with the depth supporting both low profile bezel seats and higher setting cups for pendant assemblies, while still maintaining adequate clearance for prong crowns where desired. The lack of facet junctions simplifies setting, since the cabochon edge tolerates full bezel wraps and allows for protective metal to surround the girdle without interference. Given the natural lamellar cleavage tendencies of feldspar, standard handling precautions apply, avoiding hard knocks and sudden temperature shifts, and recommended cleaning is mild soap solution with soft brush or cloth, avoiding steam or ultrasonic baths for prolonged exposure. The absence of enhancements means consumer confidence in natural origin and stability, and the Sri Lankan provenance provides a geological context prized by connoisseurs of classic moonstone material.

In summary this peach moonstone from The Natural Gemstone Company offers a technically sound package for discerning clients who prioritize cut orientation, natural color balance, and polish quality. The cabochon geometry is optimized to present characteristic adularescence while maintaining a clarity grade that preserves visual purity at eye level. At 9.57 carat and with the recorded dimensions, the piece is well suited to high end bespoke jewelry, providing both presence and technical integrity for designers and private collectors seeking a native Ceylon moonstone with no enhancement.
