All About Sterling Silver Jewelry
Sterling Silver Markings & Descriptions
The US Federal Trade Commission (FTC) stipulates that jewelry sold in the United States cannot bear silver markings or be described as silver, solid silver, sterling silver, sterling, or with the abbreviation Ster. unless it contains at least 92.5 percent pure silver.
The minimum silver content can also be stated as 925 parts per thousand of pure silver, so you might see the figures 925 or 92.5 used to designate silver content.
Copper in Sterling Silver
Copper is the metal most commonly used to make up the remaining 7.5 percent content of a sterling silver mix. Copper makes the silver harder, but gives it a tendency to tarnish, a darkening that occurs when sterling silver reacts with gases in the air or with other substances that it comes in contact with.
Caring for Sterling Silver Jewelry
Store your sterling silver jewelry in tarnish prevention cloths or bags. The treated cloth slows down the tarnishing process and keeps the jewelry from rubbing against harder jewelry that might scratch it. Try to to keep your sterling silver jewelry in a cool, dry place.
Cleaning Your Sterling Silver Jewelry
Polishing cloths are an excellent choice for cleaning your sterling silver jewelry. You might read recommendations to use toothpaste to clean sterling silver, but avoid doing that — toothpaste is abrasive and can leave scratches.
Sterling Silver Patina
Sterling silver jewelry that is worn continually often develops a lovely patina, a kind of glow combined with darkened areas. If you like the look, leave it alone. If you prefer a bright and shiny look for your sterling silver, use a polish cloth to restore the jewelry to its original appearance.
Silver and Platinum Combination
In 2003, Marc “Doc” Robinson created 3 formulas of platinum enhanced sterling silver for ABI Precious Metals in Carson, California. His sterling with platinum alloy is harder than sterling/copper blends and is tarnish resistant. Expect to see the new, more expensive alloys used to create fine silver jewelry.
