1.65 Ct. Moonstone from Madagascar

One of the rarest offerings from The Natural Gemstone Company is this exquisite semi transparent white moonstone, a superb 1.65 carat oval that measures 7.99 x 6.64 x 5.54 mm, sourced from Madagascar and presented exactly as nature intended, with no enhancement. This stone carries a near colorless intensity that allows it to sit elegantly between subtlety and presence, and its clarity is graded very slightly included when evaluated at eye level, ensuring that the gem reads clean and luminous to the naked eye. The cut is a carefully executed mixed brilliant, and the polish is excellent, leaving every facet edge crisp and every plane free of haze. Stones like this are not mass produced, they are selected and cut with an eye for proportion and light performance, and owning this moonstone is an invitation to join an exclusive circle of collectors and connoisseurs who understand that true rarity lies in natural character and restrained beauty.

The mixed brilliant cut on this oval white moonstone is the single most important factor in how it interacts with light, and the cutting choices made here were deliberately aimed at amplifying the gem is innate optical properties. The mixed brilliant approach combines a brilliant facet arrangement on the crown with a more controlled pavilion configuration, creating a balance between scintillation and depth. The crown facets act like a finely tuned lens, capturing incident light and breaking it into numerous small flashes that travel through the semi transparent body. The pavilion facets then reflect and return that light in a way that reinforces the pearly sheen that moonstone aficionados prize, producing a soft adularescence or moonlike glow that seems to move just beneath the surface as the stone or the viewer shifts. The oval outline is another subtle enhancement, its elongated symmetry focusing light along the length of the gem which gives the appearance of greater size and a more graceful play of light than a round equivalent. The table size has been carefully moderated to maintain balance between face up brightness and internal depth, ensuring that the stone presents a lively face up appearance while preserving the internal pathways that allow light to shimmer and wash across the interior.

Because this moonstone is semi transparent and near colorless, the mixed brilliant cut does more than create sparkle, it sculpts how the internal light pathways reveal the stone is character. The excellent polish is crucial here, each facet finishing allowing light to glide without interruption, which emphasizes the silky white and silvery reflections typical of fine white moonstone. Very slightly included clarity at eye level means the stone retains transparency and a clean visual window for light to travel through, yet the minor natural features add a whisper of uniqueness that tells a gem is natural origin story. In practical terms this means you will notice a refined scintillation at the facet junctions, a soft centralized glow from the table, and a delicate layering of brightness when the gem is tilted, all of which are hallmarks of a masterful cut. When set into a bespoke ring or a pendant the piece will not scream for attention, it will command attention quietly and assuredly, a trait that is prized by those who prefer objects that are unmistakably luxurious without being ostentatious.

At The Natural Gemstone Company we present this moonstone as a singular canvas for custom design, a natural treasure that invites a jeweler to create an heirloom quality setting that will highlight the stone is optical qualities.
