Opal RGB 2mm sphere

Compatible with COE 33 / borosilicate glass

These RGB 2mm spheres might be really small, but they'll still catch your eye with their multi-color flashes of green, yellow, and red fire. Like all of our RGB opals, they have an opaque black base with brilliant flashes of predominantly green fire and flecks of red, yellow, and blue. RGB opals flash predominantly green fire, whereas our black opals flash predominantly red fire.
