15.36 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

I am pleased to introduce a beautiful translucent oval grey moonstone that we are proud to offer, a refined piece that highlights the best qualities collectors and designers seek. This single gem weighs 15.36 carats, and its measurements are 17.95 x 14.27 x 8.00 mm, presented in a classic cabochon cut that maximizes the stone's soft glow. The color intensity is medium light, providing a gentle grey hue that shifts subtly with movement and light, while the translucency allows for a serene depth that reads as elegant and calming. Under standard visual evaluation the clarity is graded as very very slightly included at eye level, which means the stone is exceptionally clean to the naked eye, and any minute internal characteristics contribute to its natural character rather than detract from it. The polish is excellent, producing a smooth, mirror like surface that enhances the cabochon dome and supports any desired effect of adularescence, the moonstone shimmer that can appear as a blue white flash on movement or as a diffuse glow across the dome. This stone is untreated, with no enhancement, and its origin is Ceylon, Sri Lanka, a classic source known for producing fine quality moonstones.

As a salesperson experienced with gemstones I like to suggest how this moonstone can best be applied in jewelry to showcase its strengths, whether your preference is for a statement solitaire, a subtle pendant, or a refined masculine signet style. The oval dimensions make it ideal for a bezel set ring that protects the cabochon while framing its soft grey tone, or as the focal point of a vertical pendant that allows light to play across the dome with every movement. It would also translate beautifully into a cufflink or brooch, where its size and presence can be appreciated without being overly delicate. For matching jewelry sets, consider pairing with warm yellow gold for contrast, or with platinum and white gold for a modern monochrome effect that keeps the palette cool and sophisticated. Accenting with small diamonds or sapphires can lift the visual drama and offer a luxury finishing touch, while leaving it alone emphasizes the gemos inherent calm and organic beauty. Because moonstone interacts with light rather than relying solely on color saturation, the gem responds wonderfully to different design orientations and settings, and our experience suggests that a slightly elevated mount will encourage the best movement of light across the dome.

At The Natural Gemstone Company we value provenance, responsible sourcing, and clear communication about every gem we sell, and this Ceylon moonstone is offered with those principles in mind. We can provide additional detailed photographs, video under diffused and directional light, and independent gemological documentation or appraisal upon request, to support any custom design or investment decision. For everyday care, clean this moonstone with mild soap and lukewarm water and a soft cloth, avoiding harsh chemicals, prolonged exposure to extreme heat, and aggressive ultrasonic or steam cleaning methods that are not recommended for feldspar group gems, moonstone being part of that family. When stored, keep it separate from harder gemstones to prevent abrasion, and consider a soft pouch or a lined jewelry box. If you would like guidance on custom mounting, ring sizing, or coordinating accent stones, I am available to consult on design choices, production timelines, and secure shipping options. Please contact us with your preferences and any questions, and we will be happy to assist you in bringing this elegant 15.36 carat Ceylon grey moonstone into your collection or creation.
