What Is Rainbow Garnet and Where Does it Comes From?
Rainbow Garnet is a rare variety of andradite garnet that exhibits stunning iridescence due to a phenomenon called lamellar diffraction—a natural optical effect caused by microscopic layering within the crystal. This spectral play of color is extremely rare in garnets and only found in a handful of localities around the world.
In this documentary, Isometrica founder Tyler Kahn takes you on a journey into the science, origins, and mystique of these captivating stones. From the volcanic ridges of San Pedro Mountain, New Mexico, to the remote highlands of Tenkawa Village, Japan, and the desert deposits of Arlit, Niger, this film explores the geological conditions that give rise to these spectral gems—and why they’re so special.
