All our silver jewelry is made from 925 sterling silver and like all silver it oxidizes when exposed to air. The best way to make sure it stays nice and shiny is to wear your silver jewelry a lot. When not wearing your silver jewelry it is best to store it in an air tight container. Or to restore its shine you can treat it to some silver polish every once in a while.
Our brass jewelry is made from raw brass which ages beautifully, becoming a bit darker and getting patina over time. We love this slightly darker, worn look, but if you want your brass jewelry to be shiny again, just use some brass polish to clean it or this little trick: rub a bit of ketchup on your brass jewelry, wait for a few seconds, rinse it off, dry it off, and it will be nice and shiny again. As with silver, the best way to store your brass jewelry when not wearing it is in a clean, dry, airtight container.
