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

There are stones that catch the eye, and then there are stones that seem to hold a whisper of moonlight within their very structure. This translucent 2.64 carat cushion white moonstone is one such treasure, a gentle comet of soft light measuring 9.86 by 6.88 by 4.62 millimeters, carved into a cabochon that reveals its inner glow with unhurried elegance. Originating from the famed mines of Ceylon in Sri Lanka, this near colorless gem has been left entirely natural, no enhancement, its surface brought to life by an excellent polish that allows the light to breathe across its curves. At The Natural Gemstone Company we celebrate stones that speak of place and patience, and this moonstone carries the cool, storied air of island nights, a subtle promise of romance and quiet wonder.

The magic of this moonstone lies not in a single flash, but in the layered conversation of light within it. Its internal structure, a delicate lamellar arrangement of feldspar layers, scatters light in parallel whispers, producing adularescence, that ghostly sheen like a moonbeam moving across still water. Unlike faceted gems that rely on angles and scintillation, this cabochon embraces a softer, more intimate brilliance, a shifting shimmer that slides beneath the surface and returns as a pale blue white bar of light. This effect is not merely surface reflection, it is the stone’s anatomy at work, microscopic sheets and twins of orthoclase and albite playing with photons to create an optical phenomenon unmatched by ordinary translucence. The excellent polish and cabochon cut are deliberate choices, coaxing out the adularescent breadth of the gem, allowing the glow to travel, to grow, to rest at different angles like a secret revealed one soft moment at a time.

Clarity matters in moonstone as it does in any fine jewel, and here the clarity grade is very slightly included when evaluated at eye level, a gentle map of identity within the gem. These slight inclusions do not break the enchantment, rather they lend depth and authenticity, tiny signatures of natural formation that catch and scatter light in their own small, intimate ways. The near colorless intensity enhances the stone’s ability to act as a canvas for light, giving the adularescence room to breathe, while the cushion shape provides a romantic silhouette that flatters the hand when set. Imagine it as the centerpiece of a silver bezel, cradled in soft matte gold, or surrounded by a halo of tiny diamonds that accentuate the moonstone’s floating luminosity without overpowering it. Set as an engagement ring, a pendant, or a ring for a vow of self devotion, this moonstone promises a kind of timelessness, a luminous keepsake that transforms ordinary moments into moonlit memories.

If you seek a stone that is both poetic and rooted in geological truth, a gem whose sparkle is born of structure rather than mere surface flash, this cushion cabochon moonstone is a rare and lyrical find. Allow us at The Natural Gemstone Company to help you bring it into being, to craft a setting that honors its adularescent soul, so that wherever you go, you carry a little moonlight with you.
