14.16 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This translucent grey moonstone of 14.16 carat presents an immediate visual presence, and it was selected for collectors and connoisseurs who appreciate both classical beauty and mineralogical interest. The oval shape measures 16.88 by 13.92 by 8.47 millimeters, proportions that sit comfortably on a finger while also translating well to a pendant centerpiece. Cut as a cabochon, the stone reveals the hallmark adularescence of fine moonstone, with a soft play of light that travels beneath the surface as the stone is moved. The light color intensity and delicate grey body tone offer a subtle, sophisticated palette that complements both warm and cool metals, and the translucency allows the internal sheen to read clearly without appearing milky. When viewed in a collection, this moonstone commands attention through its serene glow, and it will function equally well as a focal gem in bespoke jewelry or as a study specimen on display.

From a gemological perspective this moonstone is a feldspar of the orthoclase and albite series, a structure that produces the iridescent adularescence due to thin layering and coherent scattering. The optical effect is most clearly developed in well cut cabochons, and this specimen was shaped with that science in mind. Clarity is graded very slightly included evaluated at eye level, a description that indicates minimal internal features which do not detract from the visual effect when the stone is worn or examined without magnification. These inclusions are characteristic of natural moonstones and often contribute to the depth and uniqueness of the sheen rather than diminishing it. There has been no enhancement, the stone is unheated and untreated, which is increasingly appreciated by educated buyers who favor natural states for provenance and long term value. The origin is Ceylon, Sri Lanka, a historical source known for producing moonstones with refined adularescence and clean body tones, and provenance from this island adds a measure of distinction to the piece.

The cabochon cut and the excellent polish are critical to the gem reaching its full visual potential, and both were executed with careful attention to orientation and dome height. The 8.47 millimeter depth allows for a generous dome, and when the lamellar layers are aligned parallel to the base this maximizes the directional movement of light that produces the characteristic moon glow. The excellent polish ensures that reflections are smooth and that surface luster contributes to the apparent brilliance rather than scattering the light. For collectors and jewelers the result is a stone that reads larger than its carat weight might suggest because of its broad oval surface and the engaging internal sheen. Settings that allow light to travel around and beneath the stone are ideal, such as open back bezels or lightly framed prong designs, because they permit the adularescence to be seen from varied angles. For a pendant the orientation versus the chain can be chosen to showcase the horizontal shimmer, while in a ring a slightly elevated setting can be used to capture movement and light.

For the educated buyer this moonstone represents a convergence of rarity, provenance, and gemological integrity. A 14.16 carat, well cut, untreated moonstone of Sri Lankan origin with very slight inclusions at eye level and excellent polish is uncommon on the market, and such stones are sought after for both aesthetic and investment reasons. The subtle grey tone with light color intensity makes it versatile across design eras, and the documented lack of enhancement preserves the natural state that discerning collectors prize. Proper care will maintain its beauty, and recommendations include avoiding prolonged exposure to harsh chemicals and extreme temperature shocks, cleaning with a soft cloth and mild soapy water, and storing it separately to prevent abrasion to the polished surface. At The Natural Gemstone Company we stand behind the provenance and description of this specimen, and we welcome requests for additional images, orientation views, or gemological reports to assist with appraisal and mounting decisions. This moonstone is a refined centerpiece that will reward both visual appreciation and scholarly interest for years to come.
