Sterling silver consists of 92.5% silver and 7.5% other alloys, most popular and widely used being copper. Copper is proven to be the best companion, improving the metal's hardness and durability without affecting its beautiful color. The small amount of copper added to sterling has very little effect on the metal's value. Instead, the price of the silver item is affected by the labor involved in making the item, the skill of the craftsperson, and the intricacy of the design.
With proper care, your fine quality sterling silver jewerly will last a lifetime.
In order to prevent your jewelry from scratches and other damage, store your silver jewelry either in a airtight container or jewelry box. Clean it with a dry soft cloth or polishing cloth, before putting it back into an airtight container. If the polishing cloth doesn't remove all the tarnish, wash sterling silver jewelry in warm water with a few drops of mild dish washing liquid. Avoid exposing your sterling silver jewelry to household chemicals, bleach or chlorinated water.
