One problem with silver jewelry, handcrafted or not, is its tendency to tarnish and darken with time. The oxidation process can be faster or slower depending on the environment. In a more humid atmosphere, your silver will tarnish much faster than in a dry area. Also if you wear your silver jewelry often, it'll slow the tarnishing because of everyday friction.
There are numerous different silver polishing products available, including polishing clothes, tarnish removing chemical solutions, and complete kits that has everything you need to keep your silver jewelry looking beautiful.
