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

This 2.45 carat oval white moonstone from The Natural Gemstone Company is a technically refined example of classic cabochon work, precisely measured at 11.02 x 7.79 x 4.50 mm. The cutter selected an oval cabochon profile to maximize adularescence, using a dome height of 4.50 mm to balance light scattering and stone stability. The gem is translucent with a near colorless color intensity, exhibiting the characteristic bluish to silvery sheen that results from microscopic lamellar intergrowths of feldspar. Clarity is graded slightly included when observed at eye level, with internal growth features that do not detract from the surface appearance but contribute to the stone character. Polishing is excellent, yielding a smooth silky surface that enhances the quality of the sheen and provides crisp light return across the dome. There has been no enhancement to alter optical properties, and the documented origin is Ceylon, Sri Lanka, a source historically noted for producing moonstones with clean body tones and pronounced adularescence.

From a craftsmanship and design perspective this specimen lends itself to settings that preserve the integrity of the cabochon, such as a low bezel or protective flush mount, which maintain the domed profile while protecting the edges and ensuring the adularescent band reads correctly from multiple viewing angles. The near colorless body color is best complemented by cool white metals, which do not compete with the stone sheen and allow the lunar play to dominate. In keeping with the heritage of Ceylon moonstones, similar stones have long been used in bridal and ceremonial jewelry across South Asia, where cutters and goldsmiths emphasized dome symmetry and polish to evoke lunar symbolism and calming optical effects. The Natural Gemstone Company sources this moonstone mindful of traditional cutting techniques, and this piece is suited for connoisseurs who value geological provenance and precise lapidary execution, as well as designers seeking a stable cabochon with a reliable, pleasing adularescence for contemporary or heritage inspired pieces.
