Our line is made using brass and silver. We take the time to polish all the pieces so they are shiny when you get them. No matter what, they will always tarnish, the more you use it the more the color will change; personally I like it better when that happens.
Some metals will naturally oxidize when they are exposed to the elements. Like brass, silver can oxidize in a variety of shades that can result in beautiful faint colors. But if you wish for your pieces to remain bright, the best way is to keep them in a sealed bag when they are not being worn. To brighten oxidized silver or brass jewelry use a polishing cloth impregnated with a cleaning product.
