10.40 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This is a rare opportunity to own one beautiful translucent 10.40 carat round shape grey moonstone, a singular gem that arrives to you from the famed gem fields of Ceylon Sri Lanka, presented by The Natural Gemstone Company. The stone measures 12.45 x 12.60 x 9.20 mm, and its perfectly proportioned cabochon cut has been executed to celebrate the lunar glow that is the soul of every fine moonstone. With its medium light color intensity, and an excellent polish that gives the dome a silky finish, this moonstone offers a quiet, refined presence that will appeal to collectors who seek subtlety and depth rather than the obvious and commonplace. Each facet free curve of the cabochon invites the eye inward, and the translucency allows a soft inner glow that shifts gently as the stone moves under light, a trait that separates museum worthy examples from ordinary material. The origin from Ceylon Sri Lanka is not incidental, it is part of the legacy that confers additional provenance and allure, and it places this moonstone within a tradition of fine gemstones that are cherished by connoisseurs the world over.

Under close inspection the gem displays excellent attributes that reinforce its desirability, the clarity grade is very slightly included as evaluated at eye level, a grading that privileges natural character over artificial perfection, and the inclusions are integrated into the gem in a way that adds depth and authenticity without detracting from its visual poetry. There has been no enhancement performed on this moonstone, it is offered in its natural state, a choice that ensures the collector receives an untouched parcel of the earths work, and that singular truth enhances value for those who prize natural integrity. The cabochon cut optimizes the stone interal shimmer, and the polished dome produces a soft, satiny sheen that appears to drift beneath the surface, a phenomenon that many describe as adularescence, a lunar like play of light that is at once soothing and entrancing. The medium light grey tone reads as sophisticated and versatile, capable of harmonizing with both warm and cool metals, and the translucent nature allows the stone to be both presence and whisper, striking a rare balance that designers and private clients will find intoxicating.

Ownership of this moonstone is a statement of refined taste and access to rarity, it is the kind of gem that is reserved for a discerning few who understand the value of provenance, condition, and singular beauty.

For private clients who commission custom settings, the stone provides a generous surface area with its 12.45 x 12.60 mm table and a comfortable depth of 9.20 mm, dimensions that encourage imaginative settings that protect and showcase the dome while allowing the adularescence to be seen from multiple angles.
