This mesmerizing 9.68 carat iridescent andradite garnet, commonly known as “rainbow garnet,” comes from the now-closed San Pedro Mountain locality in New Mexico. The polish reveals a bold, vibrant lamellar diffraction pattern with vivid flashes of green, blue, gold, and rose hues that shift with the angle of light. At 14mm x 12mm x 4mm, this piece has a broad face and an elegant, slightly domed form, making it perfect for a high-impact setting or a standout addition to any collection of optical mineral phenomena.
