15.81 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One breathtaking grey moonstone is presented here, weighing 15.81 carat, with an elegant oval shape and generous dimensions of 20.19 x 15.38 x 7.26 mm, making it ideal for a statement ring or a striking pendant. The gem displays a soft translucent body color that moves with light, revealing delicate internal glow and subtle flashes that are characteristic of fine moonstone. This cabochon cut enhances the stone's natural schiller, allowing a silky sheen to pass across the dome when tilted, and the overall visual effect is calming and refined. The color reads as a sophisticated cool grey, yet under different light conditions the stone can appear to carry faint hints of greenish and bluish undertones, which gives it a living quality that is captivating. For jewelers and collectors who seek a balance of presence and elegance, this moonstone sits comfortably between wearable size and eye catching appeal, and its oval silhouette provides classic versatility for both modern and vintage inspired settings.

From a gemological perspective this moonstone is exceptional in several important ways, it has a clarity grade described as eye clean evaluated at eye level, which means that under normal visual inspection there are no inclusions that distract from the gem's beauty. The color intensity is classified as intense, a noteworthy attribute for a grey moonstone where depth of color can greatly enhance the adularescence and perceived value. The cabochon cut has been executed with precision, presenting a smooth, evenly domed surface and symmetrical outlines that contribute to consistent light play. The polish on the gem is excellent, producing a mirror like shine where light reflections softly glide across the surface without any dull areas. Enhancement status is none, this gem is natural and untreated, with no enhancement, which will be important for buyers who prioritize natural, ethically sourced gemstones.

This moonstone comes from Ceylon Sri Lanka, a location long celebrated for producing high quality feldspar minerals, and provenance from this region often carries a reputation for careful mining and established trade channels. The warmth of origin adds an extra layer of desirability for connoisseurs who value traceable gems, and The Natural Gemstone Company stands behind the authenticity and origin reporting of this piece. In terms of design suggestions the oval form and cabochon finish lend themselves beautifully to a bezel setting that will protect the stone while showcasing its full face, or to a prong or half bezel approach for designs that aim to maximize light interaction. For a ring the depth of 7.26 mm gives a satisfying dome that will show off the adularescence, while for a pendant the length and width provide an elegant focal point that sits comfortably on the chest. Custom design opportunities include pairing with soft white diamonds to accentuate the moon like glow, or with warm yellow gold to create a classic contrast that enhances the grey body tone.

Caring for this moonstone is straightforward, its natural state and cabochon form mean gentle handling will maintain its polish and visual appeal, cleaners should avoid ultrasonic or steam cleaning, and a soft cloth with mild soap and water is the recommended routine followed by thorough drying. When designing a wearable piece consider protecting the gem from hard knocks and abrasive contact, and remind clients that long term exposure to harsh chemicals should be avoided.
