23.40 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

I am pleased to present a beautiful natural grey moonstone offered by The Natural Gemstone Company, a single translucent oval cabochon weighing 23.40 carats, with measurements of 19.24 by 13.08 by 13.08 millimeters. This specimen displays a light grey body color with a soft translucent character that allows light to move through and across the stone, revealing the signature moonstone adularescence when viewed from different angles. The gem has been shaped into a classical oval cabochon to best showcase its optical phenomena and to provide a smooth domed profile that is ideal for both contemporary and traditional settings. Clarity is evaluated as very very slightly included evaluated at eye level, which means the stone is remarkably clean to the naked eye and free from distracting flaws, and the polish is excellent so that the surface reads with a glassy, reflective finish. There is no enhancement of any kind, this moonstone is natural and untreated, and its reported origin is Ceylon Sri Lanka, a locality renowned for producing moonstones with attractive adularescence and consistent quality.

Visually the stone offers a serene and versatile palette that moves between soft grey and delicate bluish sheens depending on the light source and viewing direction. The cabochon cut enhances the internal sheen by allowing the layered microstructure of the feldspar to interact with light, producing a floating moonlight effect across the dome. At close inspection under normal viewing conditions you will observe only very very slight internal features that do not detract from the overall appearance and are in keeping with a natural, untreated material. The excellent polish minimizes surface disruptions and enhances the silky luster that moonstone lovers seek. Because this gem has no enhancement it preserves the full story of its geological origin, and Ceylon Sri Lanka is valued for producing moonstones with a refined translucency and well balanced tone. This combination of weight, clean appearance, and classic cabochon form makes this piece a desirable choice for collectors and designers who appreciate natural character and tasteful optical display.

For practical design and jewelry considerations the generous dimensions and 23.40 carat weight give this moonstone a substantial presence that works beautifully as a centerpiece for a pendant or a statement ring. The cabochon profile and moderate dome height make bezel settings particularly appropriate because they protect the stone edge and secure the cabochon while framing the adularescence, though four prong or sculpted gallery mounts can also display the face of the gem effectively while allowing more light movement. Metal choices such as warm yellow gold and soft rose gold will emphasize the creamy warmth in the lower tones, while white gold or platinum will enhance the cool grey and bluish sheen. Designers often pair moonstone with small accent diamonds or sapphires to add contrast and brilliance without overpowering the moonstone’s subtle phenomenon. For comfortable daily wear consider a low to medium bezel with a secure back and slightly raised gallery to protect the dome, and for pendants choose a setting that allows the gem to turn gently so the play of light can be appreciated from different angles. At The Natural Gemstone Company we can assist with custom mounting recommendations and can coordinate with trusted jewelers to realize your design intent while protecting and showcasing this substantial moonstone.

Caring for this moonstone is straightforward when approached with respect for its nature as a feldspar mineral. While moonstone is durable enough for most types of jewelry it is softer than many faceted gemstones and benefits from protective settings and gentle care. Clean with warm soapy water and a soft brush or cloth, rinse well and dry thoroughly, and avoid harsh chemicals, ultrasonic cleaning, and steam treatments which are not recommended for untreated moonstones. Store the gem separately from harder stones to prevent abrasion, and have settings inspected periodically to ensure the cabochon remains secure. We provide documentation regarding the gem’s weight, measurements, clarity description, polish, lack of enhancement, and origin from Ceylon Sri Lanka upon request to support provenance and confidence in your purchase. At The Natural Gemstone Company we carefully pack and insure shipments, and we are available to discuss customization, matching requirements, and any questions you may have about this moonstone. This piece represents a rare opportunity to own a naturally beautiful, untreated, and sizable moonstone that combines subtle optical drama with timeless wearability, and we look forward to helping you bring it into your collection.
