10.10 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 10.10 carat oval shape grey moonstone with dimensions of 13.08 x 11.24 x 9.37 mm, cabochon cut, clarity grade very slightly included evaluated at eye level, medium light color intensity, and an excellent polish, is presented by The Natural Gemstone Company. This single, substantial specimen exemplifies the tactile appeal and visual serenity of classic moonstone, with a soft, grey body tone that reads as elegant and versatile in a range of settings. The cabochon cut is the traditional and preferred style for moonstone, as it maximizes the stone body color and adularescence, creating a smooth domed surface that permits light to flutter gently across the stone. At 10.10 carats this moonstone is large enough to be a focal point in a bespoke ring, a statement pendant, or a collector grade cabinet piece, while its proportions at 13.08 x 11.24 x 9.37 mm offer ideal depth to showcase internal sheen and translucency without appearing flat or overly bulbous.

From a grading perspective the clarity description of very slightly included evaluated at eye level is important for a discerning buyer, because it indicates that inclusions are minimal and do not detract from the overall appearance when the gem is worn or displayed. In moonstone, inclusions often take the form of fine veil like planes or tiny mineral platelets, and their controlled presence can actually contribute to attractive optical effects rather than diminish value. The medium light color intensity gives the stone a balanced presence, avoiding the overly dark or washed out extremes that can reduce adularescence, and the excellent polish speaks to skilled lapidary work that produces a smooth, reflective dome free from polish lines or pits. The gem has no enhancement, which is a strong value proposition to educated buyers who prioritize natural state and long term stability, because untreated moonstones retain their natural optical characteristics and do not risk alteration from dyeing or filling processes.

The origin of this moonstone is Ceylon Sri Lanka, a provenance that carries historical importance and market appeal, because Sri Lankan sources have long been recognized for producing fine feldspar varieties with clean body tones and pleasing adularescence. Provenance is an important factor for collectors and connoisseurs, as it informs expectations about crystal habit and typical inclusion patterns, and Ceylon moonstones often display a combination of translucency and sheen that is prized in high quality examples. For practical considerations this stone falls within the typical hardness range for moonstone, around six to six and a half on the Mohs scale, which means it is suitable for everyday wear when set thoughtfully, but it does benefit from protective settings and care to avoid hard knocks and abrasives. We recommend bezel or partial bezel settings for rings and secure mounting for pendants, because the cabochon dome will perform best when the girdle is protected from direct impact. Routine cleaning with warm soapy water and a soft cloth will preserve luster, and avoidance of harsh ultrasonic or steam cleaning will protect the integrity of the feldspar structure.

For an educated buyer this 10.10 carat Ceylon grey moonstone represents a combination of aesthetic merit, natural authenticity, and practical versatility, attributes that The Natural Gemstone Company is pleased to offer with clear documentation and careful presentation. The size and translucency make it attractive for both contemporary and classic jewelry designs, while the untreated status and excellent polish support long term enjoyment and potential resale value. Buyers who appreciate the subtle optical phenomena of moonstone will value the way this gem balances body color and sheen, and collectors will note that the Sri Lankan origin contributes to provenance desirability.
