Sterling silver is a bright and beautiful precious metal with a long life span. The more you love and wear your sterling silver the more bright and shiny it stays. Tarnish can occur when sterling silver comes in contact with the oxygen in the air. If you are not wearing your sterling silver pieces every day, it is best to store in a resealable plastic bag or airtight container. If you do see some tarnishing, you can polish it with a jewelry polishing cloth.
Bronze has a beautiful golden tone similar to 14k yellow gold. The high copper content in brass and bronze can cause it to darken over time. This is primarily due to a reaction to water and humidity. Some people, depending on their personal PH balance, experience a green coloring to the skin when it comes in contact with bronze and brass. This is perfectly harmless and is due to the copper content. If you prefer to avoid the dark patina to the metal, try to keep your bronze and brass as dry as possible.
Gold fill is made when a layer of gold is fused to a core of base metal. The gold in gold fill is 50 to 100,000 times thicker than gold plating. This gold fill is nickel free.
