10.74 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

You are looking at a truly exceptional moonstone that speaks to collectors and connoisseurs who demand rarity and perfect provenance. This piece is a semi translucent white moonstone weighing 10.74 carats, fashioned into an elegant oval shape and given a classic cabochon cut that emphasizes its inner glow. Measuring 15.53 by 13.16 by 7.14 millimeters, this gem sits comfortably in the realm of wearable art and statement pieces alike. The stone has been graded as very slightly included when evaluated at eye level, a clarity that lends the gem subtle character without distracting from its silvery sheen. Its color intensity is near colorless, a neutral canvas that allows the delicate adularescence to take center stage, and the polish is excellent, producing a mirror like surface that enhances light play. Importantly, this moonstone has no enhancements, and its origin is Ceylon, Sri Lanka, a region celebrated for producing moonstones with refined translucency and a clean, cool shimmer. At The Natural Gemstone Company we treat each stone as a one of a kind treasure, and this moonstone is offered as a rare, single inventory item for discerning buyers seeking a unique centerpiece.

Beyond the technical specifications, this moonstone offers an uncommonly gentle but unmistakable optical performance that rewards careful observation and thoughtful design. When light meets its domed cabochon surface, one can detect a soft band of luminous blue and silvery white that seems to glide beneath the surface as the stone is tilted, a phenomenon that moonstone lovers call adularescence. Because of the near colorless body tone and the semi translucent nature of the material, this effect reads as refined and ethereal rather than bold, making the gem a sublime choice for those who prefer understated luxury. The very slightly included clarity grade indicates internal features that are natural and authentic, like tiny mineral traces that act as fingerprints of origin, and these inclusions, when present, can add depth rather than detract. The excellent polish and the precise cabochon shaping were executed to preserve and magnify the stones internal luminosity, and the proportions of 15.53 by 13.16 by 7.14 millimeters strike a lovely balance between presence and versatility. For bespoke work, this moonstone performs beautifully in a variety of settings. A halo of fine diamonds set in warm rose gold will warm and enhance the stones creamy radiance, while a bezel in cool white gold or platinum will emphasize the silvery blue adularescence for a modern, gallery like aesthetic. The smooth domed surface invites a secure bezel setting for everyday wear, while a prong set pendant can allow light to move freely around the stone for maximum effect. Because the material is semi translucent, backlighting in a pendant or an open backed ring design can yield wonderful luminous depth and make the adularescence come alive.

For those commissioning bespoke work, our design team can advise on metal choices, mounting techniques, and protective design elements to ensure the stones longevity and daily wearability. Care for a moonstone is straightforward, the stone should be protected from hard knocks and extreme temperature changes, cleaned gently with warm water, mild soap, and a soft cloth, and stored separately from harder gemstones to avoid surface abrasion. Given the stones cabochon polish and internal openness, routine inspections of the setting are recommended to ensure the mount remains secure.
