33.16 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This listing presents one beautiful translucent grey moonstone weighing 33.16 carats, oval shape, with precise dimensions of 21.82 x 17.59 x 12.42 millimeters, cabochon cut, clarity graded as very slightly included when evaluated at eye level, very light color intensity, and an excellent polish. The gem is natural with no enhancement, and the reported origin is Ceylon Sri Lanka. As a member of the feldspar family, moonstone derives its signature adularescence from the fine alternating layers of orthoclase and albite, which scatter light to produce a soft, floating sheen. In this specimen the sheen is subtle and complementary to the stone s very light grey body color, a combination that reads as elegant and versatile for both contemporary and classical jewelry designs. The cabochon profile is deliberately chosen to maximize this optical effect, providing a smooth domed surface that allows light to travel across the layered structure and emphasize the internal glow, while the excellent polish ensures minimal surface disruption to that effect.

The clarity grade of very slightly included at eye level indicates that the stone contains minor internal features which are observable under close inspection but do not significantly interfere with the overall visual performance or structural integrity of the gem. These inclusions are typical of natural moonstone and are often growth lines or minute crystal inclusions related to the rock s formation process, features that can serve as positive indicators of natural origin for the discerning buyer. Because the gem is translucent rather than fully transparent, these internal characteristics contribute to the stone s character without detracting from its luminous quality. The sizeable dimensions and weight place this moonstone in a category that is uncommon on the market, making it particularly attractive for collectors and makers seeking a statement center stone that still retains the gentle, ethereal personality that moonstone lovers prize.

The provenance of this moonstone from Ceylon, Sri Lanka, adds provenance value, as Sri Lankan moonstones are esteemed for their clarity and classic tones, and for historical continuity in supply and lapidary expertise. Compared to stones from other localities, a Ceylon moonstone of this calibre and size, presented unenhanced, speaks to a natural quality that an educated buyer can trust. For practical considerations, moonstone measures around 6 to 6.5 on the Mohs scale, so protective settings such as bezel mounts or guarded prongs are advisable to reduce risk of abrasion and chipping during everyday wear. Cleaning should be gentle, using warm soapy water and a soft brush or cloth, avoiding steam and ultrasonic cleaners which can stress the stone. The cabochon form and excellent polish also make this stone suitable for pendants where it can be enjoyed visually without excessive exposure to knocks, or for artisan rings where a protective setting preserves the gem s surface while showcasing its luminous qualities.

At The Natural Gemstone Company we emphasize transparency in description and a commitment to natural material quality, and this moonstone exemplifies those priorities through its unenhanced state, clear origin, and carefully evaluated characteristics. For an educated buyer looking for a large, characterful moonstone with a subtle grey palette, strong adularescence potential, and minimal internal features, this 33.16 carat cabochon represents a compelling option for both bespoke jewelry projects and serious collections. Its combination of size, natural origin, and fine polish make it a durable aesthetic asset, and our team is available to discuss setting options, matching considerations, and documentation to support provenance and care, ensuring that this gem can be integrated into a thoughtful and lasting piece.
