16.41 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

At The Natural Gemstone Company we present this exceptional translucent grey moonstone as a rare opportunity for the collector who seeks something truly singular, a stone that reads like a private signature on the hand of the earth. Weighing 16.41 carat, fashioned into a graceful oval shape with dimensions 15.80 x 13.13 x 11.02 mm, this cabochon cut moonstone was selected for its balanced proportions and its capacity to reveal a living play of light. Its light color intensity and excellent polish allow the surface to sing with adularescent movement, while the translucent body offers depth without losing intimacy. This gem carries no enhancements, it is wholly natural, and it traces its origin to the celebrated gem fields of Ceylon, Sri Lanka, a provenance that has produced some of the world’s most admired moonstones. Because stones of this caliber, weight, and provenance are seldom available, this moonstone is presented as a limited opportunity to own a piece that stands apart from mass produced material, an heirloom quality gem destined for a bespoke setting and an owner who values rarity.

What gives this moonstone its unmistakable signature is the subtle, internal architecture and the delicate inclusions that define its personality, details that reveal themselves to those who take the time to look. Within the translucent body, fine lamellar structures and wispy, silk like inclusions create a soft, directional glow that shifts as the stone is moved. These internal features are wonderfully restrained at eye level, earning the stone an eye clean clarity grade, yet under close examination they organize into planar arrays and minute platelets that scatter light in a way unique to this specimen. The result is a cool, ghostly sheen that can be described as lunar, a blue white flash that does not sit on the surface but seems to live within the heart of the gem. These inclusions are not imperfections in the pejorative sense, they are the fingerprint of formation, the record of temperature, pressure, and growth history, and they imbue the piece with natural character and soul. The cabochon cut, chosen with intention, lifts this internal choreography into view, allowing the adularescence to glide across the dome, producing moments of quiet spectacle that are never identical, that reward the observer with a fresh nuance each time the stone is seen.

Owning this moonstone is to join a small circle of discerning collectors who appreciate natural rarity, geological story, and handcrafted presentation. The Natural Gemstone Company curates gems with provenance and personality, and this grey moonstone exemplifies that mission. It is a stone that lends itself to a single, considered setting, a commission that will transform it into a pendant or ring that reads like a family crest, a modern talisman that carries history and subtle glamour. We invite you to imagine it set in a bespoke design that honors the stone’s translucent serenity, perhaps surrounded by cool metals that enhance the lunar shimmer, or framed by a minimal halo that allows the internal signature to remain the conversation. Because this is a naturally formed, unenhanced specimen from Ceylon, supply is finite and each stone is inherently unique. For the client who seeks exclusivity, who values origin, and who understands that true rarity cannot be replicated by treatment or embellishment, this moonstone offers a private ownership experience. Contact The Natural Gemstone Company to discuss bespoke settings, to request high resolution imagery, or to arrange an in person viewing. We will guide you through provenance documentation, mounting options, and secure delivery, ensuring that this rare moonstone becomes a treasured piece in your collection.
