Indonesian Plume Agate with an Aurora effect is a handcrafted, one-of-a-kind, or small-batch gemstone doublet, featuring natural, plume-like inclusions from Indonesia (often resembling clouds, feathers, or smoke) backed with iridescent material (like Aurora Opal or resin) to create a glowing, color-shifting effect. These stones are popular for high-end, artisan jewelry due to their unique, "sky-like" landscapes and vibrant, fiery or cool-toned colors.
