1.55 Ct. Moonstone from Madagascar

One semi-transparent rainbow moonstone, 1.55 carat, oval shape, dimensions 7.87 by 6.60 by 5.48 millimeters, mixed brilliant cut, clarity graded very slightly included when evaluated at eye level, color intensity medium light, excellent polish, origin Madagascar, no enhancement. This gem presents the delicate interplay of translucency and internal reflection that defines quality moonstone, with the mixed brilliant cut engineered to maximize internal spectral flashes while preserving a balanced crown and pavilion profile. The faceting pattern yields lively play of light across the table and facets, producing the subtle blue and multicolored schiller often described as adularescence. At 1.55 carat the stone sits in a size range that is readily adaptable to a variety of jewelry styles, and the oval outline provides a classical silhouette that concentrates perceived size along the finger or pendant axis. Clarity observations note only very slight inclusions visible at eye level, which are typical for natural moonstone and do not detract from the optical performance or structural integrity of the gem. The excellent polish enhances surface luster and allows the internal sheen to read cleanly under varied lighting conditions. Being unenhanced and untreated, the stone retains its natural character and is presented in the state in which it was extracted and cut.

The origin of this moonstone is Madagascar, a source known for producing specimens with attractive adularescence and generally good clarity. At The Natural Gemstone Company we prioritize traceability and responsible procurement, working with a network of vetted partners and miners to ensure that each acquisition aligns with clear ethical standards. Our sourcing approach emphasizes documented supply chains, verification of fair labor practices, and attention to local environmental impacts. Where feasible we engage third party verifications and field-level assessments to better understand mining conditions and community benefit, and we favor suppliers who demonstrate ongoing commitments to rehabilitation of mining sites and fair compensation for workers. We also maintain transparent records for each significant parcel, and we are prepared to share origin documentation and detailed imagery on request so that designers and collectors can make informed decisions. The fact that this moonstone has received no treatments underscores our commitment to offering natural material, allowing purchasers to own a gem whose optical properties arise from its natural crystallography rather than from laboratory processes.

For the conscious consumer building a considered collection, this rainbow moonstone combines responsible provenance, natural integrity, and practical versatility. Its moderate hardness in the feldspar group means it benefits from protective settings when intended for frequent wear, with bezel and low-profile prong settings recommended to reduce exposure to abrasion and hard knocks. Routine care involves gentle cleaning with mild soap and warm water and avoiding ultrasonic or steam cleaners, due to the stone’s sensitivity to thermal shock and impact. Designers will value the mixed brilliant cut for its capacity to translate movement into visible sheen, while collectors will appreciate the untreated state and clear documentation of origin. The Natural Gemstone Company supports custom requests and can provide additional photographs, magnified clarity images, and independent gemological assessment upon request, enabling the conscious buyer to confirm suitability for a particular design or collection objective. This piece is appropriate for those who prioritize naturally sourced gemstones with verifiable provenance, and it integrates readily into jewelry that balances aesthetic refinement with ethical consideration.
