Sterling Silver 9.25
Silver tarnish is caused by a chemical reaction with the metal and sulfur in the air. This chemical reaction is called the oxidation process. A black film forms onto the silver known as tarnish. Tarnishing is accelerated by other elements like moisture and UV rays. This explains why jewelry in humid environments tend to tarnish much quicker than it would in dry areas.
Copper, commonly found in brass and other alloys, causes skin to turn green. The acid in human sweat, combined with chemicals found in soaps, lotions and makeup react with the metal. This reaction causes a green patina or surface coating to form on the copper, and that color gets transferred onto the skin.
There is a misconception that the oxidation process has anything to do with jewelry being "real" or "fake". Unless the item is platinum, rhodium or 24k gold, it will tarnish or discolor over time - no matter who the designer is!
So head over to your favorite Etsy shop or take a scroll through the jewelry designers on your Instagram feed. Buy what you want. Preserve it with tarnish-me-not.
