It is the nature of brass to evolve and tarnish over time. Some love this antiqued, darker look, while others prefer to keep their jewelry bright and shiny. Humidity, products on your skin, and your bodies natural chemistry are some of the things that speed up this process. Polishing cloth may be used to brighten brass.
