3.99 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

I am pleased to present one exquisite translucent white moonstone from The Natural Gemstone Company, a standout example for collectors and jewelry designers who demand natural beauty and honest sourcing. This single gem weighs 3.99 carat, it is cut into a classic oval shape with precise proportions measuring 12.06 by 10.16 by 4.60 mm. The cabochon cut accentuates the stone face and allows the characteristic adularescence to float across the surface, creating a soft lunar glow that catches light from every angle. The clarity is graded very slightly included at eye level, which means the stone maintains a clean appearance to the unaided eye, while retaining the natural internal features that confirm its authenticity. Color is near colorless, providing a neutral backdrop that enhances the cool blue to white sheen inherent to quality moonstone, and the polish is excellent, giving a glossy, glass like finish that amplifies visual depth. Importantly, this moonstone has no enhancement, and its origin is Ceylon Sri Lanka, a source renowned for producing some of the world’s most desirable gem quality moonstones.

When you compare this moonstone to others commonly available on the market, several attributes mark it as superior in both aesthetic and long term value. Many mass market moonstones are smaller, more heavily included, or carry treatments intended to mask imperfections. By contrast, this 3.99 carat cabochon combines a substantial size with a near colorless body tone, which allows the adularescent phenomenon to be more pronounced and more consistently visible. The very slightly included clarity grade at eye level is a real advantage, because it offers transparency without the cloudiness that diminishes light play in lower grade pieces. The cut and polish on this piece are also above average, with a well centered dome and smooth pavilion that produce a clean, floating sheen rather than a patchy or uneven effect. Sourced from Sri Lanka, this gem carries a provenance that collectors respect, it benefits from classic Sri Lankan material characteristics, namely a delicate yet bright adularescence and a clean body color that is often harder to find in stones from other localities.

From a jewelry design and value perspective, this moonstone holds several practical benefits when compared to alternatives, making it an excellent choice for both custom and ready made pieces. At nearly 4 carat, the size is substantial enough to serve as a striking center stone for a ring or a pendant, while the oval cabochon shape is versatile for settings that showcase the dome and allow movement to reveal the shimmer. Because the stone is natural and untreated, it will age gracefully and maintain its character without the risk of enhancement fading or requiring special re treatment. Compared to synthetic or heavily treated imitations, this gem provides a tactile and visual authenticity that is immediately apparent to anyone who appreciates genuine gemstones. In terms of pairing, the neutral near colorless body responds well to both warm and cool metal palettes, and it can be beautifully accented with small diamonds or color contrast stones to create contemporary or vintage inspired looks. For everyday wear and longevity, moonstone requires mindful care due to its moderate hardness and perfect cleavage, therefore cleaning with warm water, a mild soap, and a soft brush or cloth is recommended, and aggressive cleaning methods like ultrasonic or steam should be avoided.

At The Natural Gemstone Company we stand behind the attributes we describe, and we emphasize transparency in both grading and origin information so you can make an informed choice. This moonstone is a single, unique piece that blends an attractive carat weight, a refined near colorless body, and an untreated status, creating a combination that is increasingly rare among comparable stones on the market. If you are comparing options, consider that many sellers list similar stones without clear origin or with ambiguous enhancement statements, which can mask lower quality or treated material. We provide clear measurements, a detailed clarity description, and a photographic record, and we welcome requests for additional images or video under natural and diffused lighting to verify the adularescent effect before purchase. For designers seeking a centerpiece, for collectors building a curated selection, or for clients who value ethical sourcing and honest grading, this Ceylon moonstone represents an exceptional value. Please contact The Natural Gemstone Company for further information, to request a video, or to discuss custom mounting options, and we will assist you personally to ensure this special gem finds the perfect setting.
