1.76 Ct. Moonstone from Madagascar

The journey of this rainbow moonstone begins beneath the wild, weathered ridges of Madagascar, where layers of feldspar and volcanic history cradle pockets of mineral wonder. In the early morning light, local miners gently trace seams with pick and brush, guided by generations of knowledge passed down through families, and by a deep respect for the land that yields such quiet treasures. From the moment a pale, rough piece is pulled from the earth, its story is already unfolding, a story of pressure and time that created the internal lamellar structure responsible for moonstone’s signature adularescence. At The Natural Gemstone Company we have visited these sites and worked directly with miners who practice careful extraction methods, ensuring that each parcel of rough is evaluated with an eye for ethical sourcing, and a reverence for the natural beauty that only Madagascar can provide.

Once the rough arrives in our studio, the creative and technical work of transformation begins, a process that balances the gem’s natural personality with the precision of a master cutter. This rainbow moonstone weighs 1.76 carats and is fashioned into an elegant oval measuring 8.58 by 6.45 by 5.51 millimeters, a proportion chosen to emphasize both its semi-transparency and its internal flash. The mixed brilliant cut was selected to harness light from multiple angles, marrying a faceted crown with step elements to create scintillation while preserving the stone’s soft lunar glow. Our lapidaries examined the piece under loupe and eye, grading its clarity as very slightly included when evaluated at eye level, a characteristic that affirms its natural origin and adds a whisper of individuality, while the excellent polish brings each facet to life. This moonstone has not been enhanced in any way, no heating, no coating, no treatment, just the honest reveal of a gem shaped by the earth.

When you hold this gem, whether in photographs or in person, you will notice the nuanced medium light color intensity that gives the stone its serene presence, a light that shifts and blooms as you move it beneath a lamp or the sun. The mixed brilliant cut multiplies flashes, creating tiny mirrors of light that play across the semi-transparent body, while the subtle blue-white adularescence typical of rainbow moonstone spills across the surface like a memory of moonlight on water. The oval silhouette and its dimensions make the gem versatile for designers, poised to be set as a solitaire ring, a delicate pendant, or a refined pair when matched. The very slightly included clarity assures that the gem holds visible proof of its journey from rough to refinement, inclusions that refract light into character rather than detract from it. At The Natural Gemstone Company we photograph and handle each gem carefully, and these images show how the stone reads on the hand, its presence scaled and real, ready to become an heirloom.

Choosing this Madagascar rainbow moonstone means inviting a story into your collection, a lineage that begins in ancient geology and culminates in the careful hands of artisans who understand both the science and the poetry of gemstones. We stand behind the provenance, the cut, and the untreated nature of this 1.76 carat oval, and we welcome questions about mounting options, design recommendations, or pairing directions to help this gem find its ideal setting. To preserve its gentle luster, we recommend avoiding harsh chemicals and ultrasonic cleaners, and instead cleaning with a soft brush, warm water, and mild soap when needed, and storing it separately to prevent scratches. If you would like a formal appraisal, detailed measurements, or additional high-resolution images under varied lighting to appreciate its adularescence fully, The Natural Gemstone Company will gladly assist, making sure the path from Madagascar to your jewelry box is as transparent and trusted as the stone itself.
