0.72 Ct. Rainbow Moonstone from Ceylon (Sri Lanka)

This description presents a single transparent rainbow moonstone, weighing 0.72 carat, cut into a classic cushion shape, with precise dimensions of 5.34 x 5.34 x 4.33 mm. The gem displays a mixed brilliant cut that balances faceted fire with a soft internal glow, and it has been evaluated as eye clean when examined at eye level. Color intensity is light, which allows the inherent adularescence to appear delicate and refined. The polish is excellent, and no enhancements have been applied to this specimen, preserving its natural character. Origin is Ceylon Sri Lanka, a long established source of high quality moonstone material, and this gem has been acquired and prepared for market by The Natural Gemstone Company with a focus on transparent documentation and consistent quality standards.

The journey of this moonstone began in the gem bearing terrains of Sri Lanka, where pegmatite pockets and weathered alluvial deposits host feldspar varieties that produce moonstone. Local prospectors and small scale miners recover rough material with care to avoid unnecessary breakage, and initial sorting takes place at field stations where rough pieces are classified by color, transparency, and internal structure. For this particular stone the rough exhibited notable transparency and a fine layering that suggested good potential for a mixed brilliant cut. Early decisions in the supply chain emphasize minimizing heat and chemical exposure, ensuring that the stone remains untreated. From the mine the selected rough moves to intermediate dealers and then to a cutting studio, a path that is documented by our procurement team to maintain traceability back to Ceylon and to confirm the natural, untreated status of the moonstone.

At the cutting studio skilled lapidaries evaluate each rough piece to determine the optimal orientation and cut, a process that is especially important for moonstone because of its labradorescence and internal lamellar structure. For this cushion shaped gem the cutter aligned the cleavage and lamellae to maximize the soft white to bluish adularescence while preserving as much weight as possible. The mixed brilliant faceting strategy was chosen to introduce scintillation from the crown facets while retaining broad, luminous flashes from the stone body. Precise facet junctions and careful symmetry enabled an excellent polish, which enhances light return and accentuates the stone s transparency. During cutting the gem was measured repeatedly to arrive at the final dimensions of 5.34 x 5.34 x 4.33 mm, and the finished weight settled at 0.72 carat. Final clarity assessment at eye level resulted in an eye clean grade, confirming the absence of inclusions that would be visible without magnification. No treatments or enhancements were applied at any stage, leaving the stone in its wholly natural condition.

Upon completion the gem underwent a structured quality control and documentation process by The Natural Gemstone Company, including dimensional verification, weight confirmation, cut grading, and photographic records that accompany the lot. The company s specialists inspect the polish and facet symmetry, and confirm the origin information and untreated status before the gem is offered to clients. This rainbow moonstone is well suited to a variety of jewelry settings, most notably bezel and classic prong mounts that protect the girdle and allow light to interact with the mixed brilliant facet design. Given its light color intensity and transparent body, the gem will pair effectively with both white metal settings and warmer tones depending on design preference, and it provides a refined option for solitaire rings, delicate pendants, and custom pieces that prioritize natural character. Care recommendations are straightforward, clean with mild soap and water, and avoid harsh chemicals and ultrasonic cleaning to preserve the integrity of the feldspar layers. For professionals and collectors seeking reliable provenance and a naturally untreated specimen, The Natural Gemstone Company presents this 0.72 carat cushion rainbow moonstone as a measured and thoroughly reviewed option, available with complete documentation and ready for immediate setting or secure storage.
