Usage

What is stardust? Stardust is used figuratively to mean a quality that is naively romantic. For example, someone who is in love may be said to have stardust in their eyes because they don’t recognize any of their loved one’s flaws. This is the most common sense of stardust. In fantasy stories, the term stardust is usually depicted as shining particles of dust that when sprinkled lead to a variety of magical, ethereal, or supernatural effects. Stardust is also used figuratively to mean a mass of stars that are so far away that they appear to be particles of airborne dust. Literally, stardust is cosmic dust, that is, small particles of matter floating through space that are believed to make up all matter in the known universe. Stardust can also be used as a slang term for cocaine, due to its crystalline, dusty appearance and euphorigenic effects. Cocaine is illegal in many places around the world because of its addictive nature. Example: Juliet was so in love with Romeo that she had stardust in her eyes.
