This 2.34 carat freeform cabochon from the Arlit region of Niger is a compact burst of light and geometry—cut to highlight a dominant face that radiates blazing metallic spectral diffraction. Measuring 10.1mm x 5.8mm x 3.75mm, this gem-grade andradite garnet delivers some of the brightest, most reflective lamellar iridescence seen from this world-renowned deposit.
The main face of the stone explodes with linear color bands—gold, teal, magenta, and neon green—that shimmer and shift in tightly packed diffraction patterns as the angle of light changes. The polish is precise yet minimal, allowing the natural crystal structure to guide the shape, while maximizing the visual intensity of the optical phenomenon. The result is a highly dynamic surface that catches even soft ambient light and reflects it with high-metallic brilliance.
Rainbow garnets from Arlit are prized for their combination of crystal form and vivid iridescence, but stones of this brightness and clarity are increasingly rare.
