Why is my sterling silver jewelry tarnishing?

Tarnishing is a natural process caused by moisture and chemicals from the air and the natural oils in your skin. Me&Ro jewelry may tarnish quicker than other silver jewelry due to the matte finish we apply to all of our jewelry - this creates a more open and porous surface which is more susceptible to contaminants. In this case, it is not an indication of a low-grade silver as all Me&Ro silver jewelry is made with sterling silver, which is 92.5% fine silver alloyed with copper.
