8.43 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 8.43 carat oval shape grey moonstone is now available from The Natural Gemstone Company, a gem that combines understated elegance with classic cabochon appeal. The stone measures 13.86 by 8.71 by 9.19 mm, is fashioned in a smooth cabochon cut, and has a clarity grade of very slightly included as evaluated at eye level. Color intensity is medium, which allows the stone to show a subtle, moody grey body color while still permitting a soft internal glow. The polish is excellent, producing clean reflections across the dome, and there has been no enhancement applied to this gem. Origin is Ceylon Sri Lanka, a source known for producing high quality feldspar group gemstones with refined adularescence and attractive color variety. These straightforward specifications describe a natural, well finished moonstone that will appeal to designers and collectors who appreciate authentic, untreated material with good presence and versatility.

Visually this moonstone offers a refined, gentle adularescence that appears as a milky, satin sheen moving across the dome as the light changes. The grey body tone gives the stone a contemporary, wearable neutrality, while flashes of pearly white to subtle blue can be seen when the cabochon is tilted under light. The high dome allows the internal sheen to spread smoothly and evenly, creating a ghostly, soft glow that reads as both calming and sophisticated. The translucency permits depth without losing the silky surface reflection that cabochons are prized for. Slight inclusions are present when viewed closely, consistent with the very slightly included grade, and they do not interrupt the overall visual effect. With an excellent polish and balanced proportions, the oval silhouette maximizes light play while remaining comfortable for everyday wear in finely crafted jewelry.

For jewelry design this 8.43 carat oval cabochon is an outstanding candidate for a featured center stone in a ring, pendant, or an eye catching statement pair of earrings. In a bezel setting the cabochon will be well protected and the smooth metal edge will emphasize the uninterrupted domed surface. A low profile bezel suits everyday rings, while a higher bezel or custom prong mounting can enhance the visible depth of adularescence for a pendant. Metals such as white gold or platinum accentuate cooler flashes and the grey body tone, while warm metals like rose gold create an elegant contrast that emphasizes the stone as a fashion forward focal point. The size is substantial enough to be the visual centerpiece of a bespoke piece, yet balanced enough to combine with accent diamonds or colored gemstones. For designers we can provide exact millimeter specifications and photographs from multiple angles to aid in setting design and mock up.

As a natural gemstone sourced from Ceylon Sri Lanka this moonstone carries the appeal of provenance and natural formation, and its untreated status reinforces its authenticity and collector interest. Care recommendations include gentle cleaning with warm soapy water and a soft cloth, avoiding ultrasonic and steam cleaning as a precaution for feldspar group gems, and protecting the stone from prolonged exposure to extreme heat and harsh chemicals. When setting the cabochon, consider protective settings and avoid situations where the gem may be struck or abraded, since moonstone has moderate hardness and benefits from secure mounting. We recommend professional appraisal for insurance purposes, and The Natural Gemstone Company can assist with documentation and additional imagery. The combination of weight, dimensions, polish, and natural adularescence makes this stone a distinctive choice for clients and makers seeking an elegant, authentic moonstone with balanced character.
