This extraordinary 8.33 ct rainbow garnet crystal from San Pedro Mountain, New Mexico, stands as one of the most exceptional pieces ever recovered and cut from this rare locality. Featuring an unusually high number of polished crystal faces, each meticulously hand-finished to reveal the internal lamellar diffraction at its peak brilliance, the stone erupts in intense spectral iridescence—neon flashes of blue, violet, magenta, green, and gold shimmer vividly across its surface. This is not just a beautiful stone—it is museum quality, a true rarity among hundreds of pieces that have passed through the polisher’s hands.

Of the many rainbow garnets I’ve personally cut from San Pedro, this crystal ranks among the top five for both optical performance and overall aesthetics. The locality itself is already known for producing a highly limited quantity of iridescent andradite garnet, with most pieces displaying only subtle or localized diffraction. Stones of this caliber—combining size, color intensity, clean geometry, and multiple optimized faces—are exceptionally rare, even in the context of San Pedro’s limited output.

Whether acquired for a world-class mineral collection or transformed into a masterwork of talismanic jewelry, this piece embodies the highest potential of what this New Mexican locality has to offer.
