2.73 Ct. White Cabochon Moonstone from Ceylon (Sri Lanka)

This listing presents a beautiful translucent 2.73 carat oval shape white moonstone, with dimensions of 9.21 x 6.93 x 6.84 mm, cut as a cabochon to maximize its classic adularescent sheen, near colorless color intensity, and an excellent polish that gives crisp reflections across its dome. The clarity grade is evaluated as very very slightly included when examined at eye level, and the stone has received no enhancement, coming to you in wholly natural condition. This specimen originates from Ceylon, Sri Lanka, a source long respected for producing moonstones with refined optical properties and clean material, and it is offered by The Natural Gemstone Company, specialists in responsibly sourced and carefully evaluated fine gems. The cabochon cut is the traditional and most effective form for moonstone, allowing the internal feldspar layering to interact with light and present the soft floating shimmer that collectors and connoisseurs prize.

Inclusions in moonstone are not flaws in the conventional sense, they are intrinsic markers of the gem and often serve as its fingerprint, adding character and provenance. In this moonstone the internal features are extremely subtle, consistent with a very very slightly included grade at eye level, so that only under magnification do you observe the delicate lamellar structure and minute platelets that produce the adularescent effect. These internal lamellae and tiny fluid or mineral inclusions can orient and scatter light in such a way that a bluish or silvery sheen appears to move beneath the surface, a phenomenon unique to orthoclase and plagioclase feldspars. For the educated buyer, these inclusion patterns are valuable, because they corroborate the gem’s natural formation process and its Ceylon origin, and they make each stone unique in a way that faceted clarity grades alone cannot convey. The very very slightly included evaluation means that the inclusions do not distract from the visual appeal, while still serving as verifiable identifiers under loupe or microscope.

From a technical and investment perspective, this moonstone combines attributes that appeal to discerning purchasers. The weight of 2.73 carat and the oval proportions of 9.21 by 6.93 by 6.84 mm make it well suited for a centerpiece in a ring, a refined pendant, or an elegant pair when matched, while the cabochon dome and excellent polish ensure the adularescence reads smoothly across the surface without interruption. The near colorless body color provides versatility, allowing the stone to pair well with white metals for a modern aesthetic or with warm gold for contrast, and the absence of enhancement means there is no concern about treatments that could alter value or require disclosure. Origin from Ceylon adds an extra layer of desirability, because Sri Lankan moonstones are often associated with fine crystalline structure and a pleasing, clean sheen. For buyers focused on authenticity and long term satisfaction, the combination of natural origin, clear material at eye level, and skilled cutting and polishing represents both aesthetic merit and collector value.

Proper care and verification will preserve the beauty and provenance of this moonstone. Moonstone has a moderate hardness and perfect cleavage, so it should be set and worn with designed protection in mind, avoiding impact and harsh chemicals, and cleaned gently with warm water and mild soap and a soft brush. We recommend viewing with a 10x loupe or a simple microscope to appreciate the very very slightly included internal characteristics that authenticate the gem, and we can provide close up images or facilitate third party gemological documentation on request. The Natural Gemstone Company stands behind the description and sourcing of this moonstone, and we are available to discuss its suitability for your intended design, to provide additional photographs or videos that demonstrate the adularescence, and to advise on settings that will best preserve and display this special stone.
