5.51 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing presents a single translucent peach moonstone weighing 5.51 carat, cut into an elongated oval form with dimensions 11.40 by 7.83 by 7.82 mm, finished as a classic cabochon. The cutter has maintained an evenly domed profile that maximizes the internal light backscatter typical of potassium feldspar based moonstones, producing a soft, pearlescent sheen rather than discrete facets. Color is assessed as medium light peach, with a warm pastel saturation that remains even across the table and crown of the cabochon. Origin is Ceylon, Sri Lanka, a source known for producing stones with delicate, warm body tones, and this specimen is presented without any enhancements, ensuring natural color and structure. The polish has been evaluated as excellent, yielding a smooth, reflective surface that enhances the stone s translucency and allows subtle optical effects to be read cleanly under directional lighting.

Clarity grading at eye level is very slightly included, noting a small population of fine internal growth features and pinpoint inclusions that are typical of moonstone microstructure, and that do not materially interrupt the adularescent effect. The internal layering responsible for the schiller in moonstone is intact and well oriented, which indicates that the lapidary oriented the rough to preserve the albite exsolution lamellae alignment, thereby optimizing the soft glow across the dome. Surface integrity is excellent, with no polish lines or pits evident under loupe inspection, and the girdle of the cabochon has been uniformly finished to facilitate secure bezel seating. Proportions favor optical continuity, with the dome height balanced to present adularescence when viewed face up, while still allowing for controlled depth perception through the pavilion, which contributes to the sense of translucency rather than opacity.

From a design and setting perspective this 5.51 carat peach moonstone is particularly well suited to bezel or halo settings that protect the domed surface while allowing the stone s color and sheen to read unobstructed. The medium light color intensity complements warm metal choices such as 14k or 18k rose gold, which will enhance the peach tones, while a soft white metal will emphasize the stone s adularescence for a cooler presentation. For fine jewelry use where daily wear is anticipated, a bezel setting is recommended to minimize edge knocks against the cabochon outline. The Natural Gemstone Company guarantees provenance from Sri Lanka and confirms no treatments have been applied, a point of interest to collectors and gemologists who prioritize natural state material. Care recommendations include avoiding ultrasonic cleaning for set pieces, using mild soapy water and a soft brush for routine maintenance, and storing the gem away from harder stones to prevent abrasion to the polished dome. This specimen s combination of precise cabochon cutting, even medium light peach coloration, very slight inclusions at eye level, excellent polish, and verified Ceylon origin makes it a technically appealing choice for connoisseurs seeking a natural, high quality moonstone for a bespoke jewelry commission.
