Sterling Silver Composition:
While pure silver can be combined with many different types of metals, sterling silver is created when combining pure silver with copper. Sterling silver jewelry can be composed with different amounts of copper but is most often seen with the .925 stamp, meaning that the composition is of 92.5 percent silver and 7.5 percent copper. This has been found to be a good combination for maintaining the silver's durability without harming its sparkle.
Caring for Your Sterling Silver Jewelry:
Silver should not come into contact with harsh household chemicals such as bleach, ammonia, or chlorine.
