Silver Jewelry
Silver jewelry makes use of a soft transition metal which
is white and lustrous. A transition metal, like all other metals, conducts
heat and electricity and is both ductile and malleable. However, they
electrons which they use to combine with other elements are present
in more than one shell.
Traditionally, silver jewelry is created as an alloy of 7.5% copper
and 92.5% silver. This is referred to as sterling or standard silver.
The United States requires the use of at least 92.5% fine silver for
an alloy to be marketed as silver. The sterling type is harder than
pure silver with a lower melting point.
To give sterling silver jewelry a shiny finish, it is often plated
with a thin coat of .999 fine silver. The term for this is flashing.
For a bright and shiny look, it may be plated with rhodium. It is also
coated with gold for that type of appearance.
