925 Sterling Silver Tips and Information
All real or sterling silver can tarnish under the right/wrong conditions but the good news is that sterling silver can be cleaned and polished to as good as new.
Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed. Silver oxidizes faster in places with a lot of light and high humidity.
Also contact with products like cosmetics, hair spray, perfume, deodorant, body lotion, bleach, etc., can speed up the oxidizing process.
Besides that, the natural oils that your skin produces can also react to your silver jewelry. The extent to which the silver reacts with these substances from your skin is highly dependent on the type of food you eat, alcohol consumption and whether you are taking medication. These things influence the acidity of your skin, which can cause a reaction. Also sweat (which ammonia occurs in) raises the acidity of the skin and could tarnish the silver.
That silver jewelry that turns black would be made of a less silver content or even be no silver, is incorrect and a myth. The oxidation of silver jewelry is a sign that it is really silver.
