It is a beautiful, durable material that is high prized by its owners. The word sterling is said to come from Easterling in Germany which was said to be the source of sterling silver centuries ago. Contrary to popular belief, sterling silver is not pure silver. Pure silver is usually referred to as fine silver.
Pure silver is relatively soft.
To give silver more durability when used in jewelry, it is combined with an alloy to change its physical characteristics. The most common metal with which silver is combined is copper. The care of sterling silver jewelry is quite easy. The speed with which it will tarnish varies. Sometimes it occurs within a few days and sometimes a longer period will elapse.
