Originally crafted as projector components, these cube-shaped optical glass prisms contain a special internal film that separates light into its three primary colours: red, green, and blue. Some prisms are discarded due to minute imperfections such as scratches or chips. We transform these into captivating light-reflecting objects by sealing them in acrylic resin. When touched by sunlight―especially at dawn or dusk―they emit rainbow-like light. The Prism Ball can be rolled across your desk or displayed using the included ring. Available in glossy and matte finishes. Material Acrylic / glass
