Sterling silver is called '.925 sterling silver' because it contains 92.5% fine silver, the remaining 7.5% is copper, which makes it stronger/harder and also has the unfortunate side-effect of causing it to oxidize when exposed to moisture and air. Oxidization, or tarnish, in sterling silver, is black, so you may think your jewelry is dirty. Often it just needs a buff with a jewelry polishing cloth to look as good as new. We are happy to polish, buff and refinish sterling silver jewelry for a small fee.
