2.73 Ct. Rainbow Moonstone from Madagascar

This pear shaped rainbow moonstone from Madagascar weighs 2.73 carats and measures 12.50 by 8.62 by 5.42 millimeters, and its mixed brilliant cut sets it apart from the more common cabochon moonstones on the market. Where many moonstones are opaque or heavily included and rely solely on adularescence for interest, this transparent gem delivers both a clear body and a lively spectral flash, producing the rainbow play of color that gives it its name. Graded very slightly included at eye level, the stone reads as virtually eye-clean in everyday wear, so it offers the visual purity buyers expect from higher-end gems without the premium of rare flawless material. Its light color intensity and excellent polish create crisp, mirror-like facet surfaces that reflect light with greater precision than typical moonstones, and because there is no enhancement, you receive the full authenticity and stable beauty of a natural, untreated Madagascar gem. The Natural Gemstone Company presents this piece as a superior alternative for clients who want the mystique of moonstone with the brilliance and versatility of a faceted gem.

From every angle this moonstone rewards inspection, and the mixed brilliant cut is key to that effect. Crown and pavilion facets have been balanced to funnel light into the stone and scatter it as delicate prismatic flashes, so motion and changing light produce new colors and glints without revealing distracting dark zones. The pear outline flatters finger and pendant settings, its proportions creating an apparent size that feels larger on the hand while maintaining excellent symmetry for secure bezel or prong mounting. The very slightly included clarity means internal features are minimal and do not interrupt the gem’s depth or rainbow sheens, while the excellent polish ensures each facet edge catches light cleanly, enhancing scintillation and perceived clarity. Compared with treated, heavily included, or poorly cut alternatives, this Madagascar rainbow moonstone offers better optical performance, greater longevity, and a naturally elegant appearance that stands out in bespoke jewelry. For those seeking a moonstone that combines natural origin, uncompromised authenticity, and superior faceting craftsmanship, The Natural Gemstone Company’s offering is a confident choice for creating a distinctive, high-value piece.
