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

One beautiful transparent 3.72 carat oval shape white moonstone, dimensions 13.33 x 7.10 x 4.81 mm, cabochon cut, clarity grade very slightly included evaluated at eye level, colorless color intensity, excellent polish, no enhancement. The oval cabochon has been shaped with a measured dome to maximize adularescence while preserving transparency, producing a soft internal sheen that runs cleanly across the length of the stone. The cutter maintained a consistent table curve and symmetrical outline to ensure even light return and to minimize directional bruising of the feldspar layers, while the moderate height relative to length optimizes both wearability and the optical float that is characteristic of high quality moonstone. Polishing techniques were applied to remove lap marks and to achieve a smooth lamp finished surface, enhancing light transmission through the gem and presenting the internal lamellar structure without the visual interruption of surface blemishes. Clarity evaluation at eye level indicates only very slight inclusions, which in moonstone often manifest as fine growth lines or tiny fluid healed fractures that do not impede its adularescent effect, and the transparent body tone with colorless intensity allows for superior gemological assessment and versatile setting options.

Provenance from Ceylon Sri Lanka adds demonstrable value to this specimen, Sri Lankan pegmatitic and alluvial deposits are known for yielding moonstones with exceptional transparency and clean adularescence due to well developed orthoclase layering and minimal iron staining. Historically Ceylon material commands a premium for its combination of clarity, sheen, and stable body color, attributes that are verified by our no enhancement statement and by the measured dimensions and weight of this 3.72 carat stone. At The Natural Gemstone Company we document origin as part of our grading protocol because provenance influences both market desirability and the interpretive grading of optical phenomena, and collectors and designers seeking authentic Sri Lankan moonstone often prioritize untreated pieces for longevity and resale integrity. This cabochon is ideally proportioned for bezel or low prong settings to protect the dome while preserving the continuous sheen across the surface, and it presents as a technically refined option for bespoke jewelry, connoisseur collections, or gemological study, reflecting precise cutting, ethical sourcing, and the geological pedigree associated with Ceylon material.
