4.34 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing from The Natural Gemstone Company presents one beautiful translucent brown moonstone, weighing 4.34 carats, with dimensions of 13.36 by 10.37 by 4.34 millimeters. The gem is an oval shape, cut en cabochon to showcase its silky surface and internal light play, and it displays a medium color intensity in an even warm brown tone. Clarity is graded as very very slightly included, evaluated at eye level, and the piece has an excellent polish that enhances surface luster and eye appeal. There have been no enhancements applied to this moonstone, and its reported origin is Ceylon, Sri Lanka, a locality long regarded for producing fine feldspar specimens. For an educated buyer, these core data points define the gem classically, with natural provenance and an untreated status that preserve both physical integrity and market desirability.

To put the clarity and optical presentation in context, moonstone is a microcline and albite intergrowth within the feldspar group, and its visual character comes from the lamellar internal structure rather than from high refractive sparkle. A cabochon profile is the traditional and optimal cut for moonstone, because it allows light to interact with the layered structure and produce a soft internal sheen and depth. The grading label very very slightly included at eye level indicates that any internal features are extremely fine and not distracting to the overall appearance when viewed without magnification. In practical terms, this means the stone reads as clean and translucent to the naked eye, maintaining good light transmission while offering that characteristic moonstone softness. The medium brown color provides an uncommon and refined palette for moonstone, often preferred by buyers seeking subdued warmth rather than the more familiar blue adularescence. The excellent polish further supports visual clarity, allowing the cabochon surface to present uniform reflections and to display the stone consistently in different lighting environments.

From a value perspective an educated purchaser will weigh size, treatment status, origin, and aesthetic quality. At 4.34 carats and measuring over 13 millimeters across the long axis, this moonstone occupies a desirable size range for use as a prominent center stone in rings and pendants. The untreated nature of the gem adds to intrinsic value, because enhancements such as dyeing or resin filling, which can be applied to some stones in the market, are absent here. Sri Lankan provenance contributes to market preference as well, because Ceylon has a documented history of producing well formed, consistently colored feldspars with attractive translucency. The clarity grade and excellent polish combine to support a high visual grade, and the uniform medium color intensity avoids the pitfalls of overly dark or mottled specimens. For collectors and designers the gem offers a harmonious balance of rarity within the brown moonstone subset, sound optical performance, and immediate readiness for fine jewelry settings without additional treatment.

Practical considerations for setting, care, and verification are straightforward. The cabochon profile and thickness of 4.34 millimeters lend themselves well to bezel settings that both protect the girdle and showcase the dome, though skilled jewelers can also integrate the stone into prong or halo designs to emphasize its oval silhouette. Given feldspar hardness near 6 to 6.5 on the Mohs scale, care should be taken to avoid hard knocks and prolonged exposure to harsh chemicals, and cleaning with warm soapy water and a soft cloth is recommended. The Natural Gemstone Company stands behind the accuracy of the description and is happy to provide additional photographs, viewing angles, and any requested supporting documentation to reassure acquisition decisions. For buyers seeking a natural, untreated, and attractively proportioned moonstone with clear provenance and excellent finish, this 4.34 carat Ceylon brown moonstone is a strong specimen that combines aesthetic restraint with gemological integrity.
