glitter:

 Glitter describes an assortment of small, flat, reflective particles. Glitter reflect light at different angles, causing the surface to sparkle or shimmer. Glitter is like confetti or sequins, only smaller. Since prehistoric times, glitter has been made and used as decoration, from many different materials including stones such as malachite, galena, mica, insects, and glass. Modern glitter is usually manufactured from plastic.
