This process is called "Flashing." At times a flashed piece of jewelry will also have a layer of nickel or copper plate between the two silver layers.
Other common methods used are Rhodium plating, Gold plating and Anti-tarnish plating. The reason for manufacturers to plate Sterling Silver is to restore the even, consistent color lost as a result of "Firescale," the discoloration of silver caused by soldering findings and posts onto the jewelry
All of these plating methods give the jewelry a longer, brighter life. However, these items cannot be sized or machine buffed without being re-plated.
Sterling Silver jewelry will tarnish. this is not a defect, but the reaction of a natural chemical process that takes place when sterling silver is exposed to oxygen and other elements in the air.

Silver is widely distributed in nature, but in comparison with rarely. Silver crystals are uncommon; they occur occasionally as indistinct cube or wirey aggregates. Scaly , dendritic, , and massive habits are common.
Although much of the worlds silver production is byproduct of refining lead, copper, and zinc, deposits of native silver are also commercial important. As a metal for jewelry or coinage. it is harder than gold but softer than copper.
Next to gold, it is the most malleable and ductile metal. The chemical symbol for silver, Ag, comes from the Latin word for silver, argentum , which in turn derives from a Sanskrit word meaning "white" and "shining."
