This striking 20.1 carat rainbow garnet crystal from San Pedro Mountain, New Mexico, showcases a vivid display of spectral diffraction across every natural and polished facet. The piece has been selectively polished to enhance the natural geometry while preserving the crystal’s authentic aesthetic. Its dominant neon green iridescence is electrified with gold and cobalt blue undertones, accented by flecks of warm orange that flicker across the textured surface. Measuring 18.25mm x 13.3mm x 6.9mm, this garnet is a rare example of the locality’s finest material—where lamellar diffraction manifests in complex metallic patterns that shimmer like shattered light frozen in stone. A stunning specimen for any collector or a potential centerpiece in high-concept jewelry.
