11.06 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One translucent oval white moonstone weighing 11.06 carats, measuring 13.28 by 11.93 by 9.28 millimeters, cabochon cut, offers a classic expression of adularescence and gentle body color, presented by The Natural Gemstone Company. The facet free cabochon form enhances the stone color and optical sheen, while the near colorless intensity supports a clean, cool glow that reads well in a range of settings. Clarity is graded very slightly included when evaluated at eye level, this indicates the presence of only minor internal features that require close inspection to notice, and these do not interrupt the overall translucency or the play of light. The polish is excellent, producing a smooth reflective surface that promotes a bright, even shimmer across the dome, and the gem has no enhancement, confirming that its character and tone are natural from origin. This moonstone originates from Ceylon, Sri Lanka, a source historically recognized for producing moonstones with appealing transparency and refined adularescence, qualities that experienced buyers seek when building a considered collection.

From a gemological perspective this moonstone is valued for the quality of its adularescence, which arises from the intergrowth of lamellae within the feldspar structure that scatter light to produce the signature floating sheen. The near colorless body combined with translucency allows the sheen to read clearly without competing color tints, and the cabochon profile maximizes the surface area where adularescence appears, creating a pleasing and consistent visual effect. A clarity assessment of very slightly included at eye level suggests that the stone remains attractive to knowledgeable buyers who prioritize optical performance over absolute internal clarity, because the minor inclusions are not positioned to obstruct the central sheen. The excellent polish further increases wearable appeal because a finely polished surface reduces micro roughness that can diminish luster and make adularescence appear dull. Origin from Ceylon is a positive factor for many connoisseurs, because Sri Lankan moonstones are well regarded for their combination of cleanliness, translucency, and a soft white or bluish sheen, and the absence of enhancements preserves the gem as a natural specimen rather than a treated material.

For the educated buyer this moonstone represents a compelling balance of size, optical character, and natural provenance. At 11.06 carats the piece is substantial for use in a statement pendant or a bold ring, and the dimensions lend themselves to traditional bezel or cabochon settings that protect the dome while showcasing the sheen. Designers often set fine moonstones in a low bezel or in a halo of small accent stones that contrast without overpowering the soft adularescence, neutral metals such as 18 karat white gold or sterling silver typically complement the near colorless body color, while warm metals can create an antique style presentation. The lack of enhancement makes this gem appealing for collectors who prefer material in original state, and it simplifies valuation and resale considerations because there are no disclosed treatments to account for. We recommend that buyers inspect the stone under both natural and controlled lighting to appreciate the shift in adularescence, and for high value transactions a third party report can be arranged to document weight, dimensions, clarity comments, origin, and the lack of enhancement.
