11.34 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This translucent white moonstone presents as an oval cabochon weighing 11.34 carat, with precise dimensions of 16.63 x 11.71 x 7.61 mm. The cabochon cut is executed to emphasize the gemology of moonstone, yielding a smooth domed surface and a broad plane for adularescence to manifest. Evaluated at eye level the clarity is graded as eye clean, indicating an absence of inclusions visible without magnification and a clear, undistracted visual field that allows light to interact uniformly across the stone. The color intensity is near colorless, permitting the soft blue to white sheen to appear delicate and uniform, while the polish is assessed as excellent, providing a high degree of surface finish that maximizes reflective quality and tactile smoothness. There are no enhancements applied to this specimen, identifying it as a natural, untreated moonstone, a characteristic that is increasingly sought after by collectors and connoisseurs who prioritize natural origin and intact optical phenomena.

The provenance of this moonstone from Ceylon, known in modern designation as Sri Lanka, contributes materially to its aesthetic and market value. Sri Lanka occupies a renowned position in the historical and contemporary gemstone trade for feldspar group gems, with a geological milieu that produces adularia and orthoclase material of exceptional transparency and adularescent quality. The island s alluvial and primary deposits have yielded moonstones with a particular combination of translucency, sheen clarity, and hue that differs subtly but perceptibly from specimens sourced in other localities. In practical terms this means that a Ceylon moonstone often displays a more even and sustained sheen, and a controlled body color that supports high end cutting and setting applications. Beyond the optical characteristics there is an established market precedent that assigns a provenance premium to Sri Lankan moonstones, born of long term collector preference, documented trade history, and the reputation of Sri Lankan lapidary skills. For buyers who regard origin as an integral component of value, the Ceylon designation is a meaningful attribute that informs both aesthetic appreciation and long term investment considerations.

From a design and collection perspective this oval 11.34 carat, cabochon cut moonstone is well suited to a range of settings where the adularescent display can be showcased without interruption, including solitaire rings, pendant centers, and bespoke designer pieces. The stone s dimensions allow for substantial presence in a mounting while maintaining classic proportion, and the eye clean clarity ensures that the sheen remains the primary visual focus. The absence of treatment preserves the natural character and structural integrity of the mineral, and the excellent polish supports durability against surface wear when set and maintained in accordance with standard gemstone care. The Natural Gemstone Company provides detailed documentation of the gem s measured attributes and origin, and applies consistent selection criteria to represent specimens with accuracy and transparency. For specialists seeking a moonstone whose origin, natural state, and physical specifications align with connoisseur standards, this Ceylon example embodies the combination of geological provenance, optical quality, and lapidary execution that defines premium moonstone material.
