1.66 Ct. Moonstone from Madagascar

One exquisite semi transparent 1.66 carat round rainbow moonstone awaits the collector who seeks something truly singular, it measures 7.47 x 7.17 x 5.79 mm and carries a mixed brilliant cut that maximizes its inner light. The clarity grade is very slightly included evaluated at eye level, the color intensity sits at a refined medium light, and the polish has been brought to an excellent finish, all of which attest to meticulous selection and cutting. Free of enhancement and sourced from Madagascar, this gem arrives to you in its natural state, a rare offering that stands apart from mass produced pieces. At The Natural Gemstone Company we present this stone as a limited opportunity, an elegant treasure for a discerning owner who values provenance, purity, and the kind of subtle sophistication that only a hand chosen rainbow moonstone can deliver.

The reflective quality of this moonstone is its signature, a soft adularescence that plays across the surface like moonlight on calm water, a phenomenon distinct from the flash and fire of other gems. Compared to common white moonstones this Madagascar piece shows a more pronounced and layered blue white sheen that shifts with movement and light, thanks to its semi transparent body and masterful mixed brilliant cut, it offers a depth of inner glow rarely encountered in stones of this size. Against labradorite the contrast is instructive, labradorite yields bold metallic flashes of color known as labradorescence, dramatic and directional, while this rainbow moonstone maintains a more ethereal, diffused shimmer that reads as refined and wearable. Against opal its behavior is subtler still, opal exhibits play of color that scatters vivid hues across a mosaic, whereas the moonstone produces a single serene band of light that enhances wearable elegance rather than commanding attention. Even when set beside high dispersion stones like white topaz or diamond simulants this moonstone offers a different pleasure, it does not glitter with scintillation, it sighs with a luminous inner pulse that complements skin and metal in a way that only natural adularescence can achieve.

Owning this 1.66 carat round rainbow moonstone is a declaration of taste, a decision to join an exclusive group of collectors who prioritize natural beauty, exceptional finish, and verifiable origin. The Natural Gemstone Company invites you to consider this rare Madagascar specimen as the centerpiece of a bespoke creation, a private acquisition that will remain quietly celebrated for generations.
