For this 9mm Hotfix cosmic delta rhinestone, Swarovski used a smoked topaz color that goes particularly well with dark blue. You can add this yellow triangle-shaped rhinestone to craft projects, scrapbooks or clothing. It comes with glue already on the back so that you don't have to mess with dried out tubes. All you need to do is heat it with an iron or a Bejeweler Stone Styler. This rhinestone is not recommended for leather, water resistant material or non porous surfaces.
