4.62 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing describes a single natural blue flash moonstone weighing 4.62 carats, presented in a classic oval silhouette. The gem measures 10.76 by 8.58 by 6.47 millimeters, and it has been shaped as a cabochon to best display its characteristic adularescent effect. The material is opaque with a medium light color intensity, and the surface exhibits an excellent polish. Clarity is graded as very slightly included when examined at eye level, with minor internal features that do not detract from the overall visual appeal. There has been no enhancement performed on this stone, and its documented origin is Ceylon, Sri Lanka. The Natural Gemstone Company offers this piece as an example of traditional Sri Lankan moonstone material, presented in a form well suited for both contemporary and classic jewelry designs.

Optical character and physical presence are central to the appeal of this moonstone. The cabochon cut emphasizes a cool blue flash that appears to move beneath the surface when the stone is gently rotated in light. This adularescence results from submicroscopic lamellar twinning within the feldspar structure, producing a soft, internal glow rather than a surface sheen. Under daylight the body shows a translucent to opaque milky field with a distinct blue sheen that reads as a floating band of light when viewed from different angles. The oval outline and moderate dome height provide a balanced profile that works well in settings where the optical effect is intended to be viewed from above, such as bezel set rings or pendant mounts where the stone sits prominently against the skin.

From a gemological and workmanship perspective the piece reflects careful selection and cutting. The proportions of the cabochon have been chosen to maximize the adularescence while maintaining a durable thickness, and the excellent polish ensures clean light return and minimal surface disruption. The very slightly included clarity grade indicates the presence of small natural features common to moonstone, which do not compromise structural integrity. With a Mohs hardness around six to six and a half, moonstone requires considered design and wear practices, but when properly set and cared for it performs well in daily wear pieces. The absence of enhancement and the clear documented origin from Ceylon add to the gemological transparency and collectibility of the specimen.

Discussion of metaphysical and healing associations follows traditional and contemporary usage rather than clinical claims. Moonstone has long been associated in various cultural and esoteric traditions with intuition, emotional balance, and cyclical energies. Practitioners and collectors commonly attribute to moonstone a capacity to enhance introspection, to soothe heightened emotions, and to support new beginnings and transitions. The blue flash variety in particular is often linked to clear mental focus and an enhanced ability to receive subtle impressions, with some users employing it in meditation or dreamwork to encourage lucid dreaming and recall. These attributions are experiential and symbolic, and descriptions are provided to reflect historical and cultural associations rather than scientific evidence.

This moonstone is offered as a versatile component for fine or artisan jewelry, as a collector specimen, and as a gift for those who appreciate both the geological story and the traditional associations of the gem. Its dimensions and cabochon form make it well suited for custom ring designs where a secure bezel can protect the stone, for pendant settings that allow the adularescence to be viewed in motion, and for brooch or cuff applications where surface exposure is moderate. The photographs illustrating the stone in hand provide scale and context while preserving anonymity. The Natural Gemstone Company presents this moonstone with full disclosure on weight, measurements, clarity, polish, enhancement status, and origin to support informed selection and design planning.
