What
is Sterling Silver?
Sterling
silver is one of the three precious metals, the other two being
gold and platinum. Sterling silver is an alloy (mix) of 92.5% silver
and 7.5% of another metal, usually copper. This sterling silver
standard of 925 was set by the British by 1300 ad. when the term
"sterling silver" was established. This is why you see
925, 925/1000, or "sterling" stamped into your sterling
silver. This ensures that your silver jewelry or other silver items
are sterling.
Copper
us usually used and has been proven through trial and error to be
the best metal to alloy with silver. It provides strength, durability,
and it enhances silvers bright natural sheen. However, other metals
may be used. Some of the more common replacements for copper are
zinc, platinum, geranium and a variety of other additives including
silicon and boron. These metals are used in place of copper to improve
various properties of the sterling alloy such as reducing casting
porosity, eliminating fire scale and increasing resistance to tarnish.
At this time there is no industry standard formula for tarnish resistant
sterling silver, therefore the competition is high between the manufacturers
offering tarnish resistant sterling silver.
What
is Pure Silver?
Silver
itself is an element and can be found on the periodic table. Fine
silver, which is 99.9% silver, is usually too soft for producing
any functional objects or jewelry. Although you can find jewelry
or elements of jewelry using fine silver. This is why copper or
other metals are alloyed with silver. These alloys give silver strength
and durability while preserving the precious metal content.
Where
did the name sterling silver come from?
There
are a few theories of the origin of the term "sterling silver."
Theory
1
The term emerged in England by the 13th century. The 1971 Oxford
English Dictionary states that the early middle English name sterling
was presumably descriptive of small stars that were visible on early
Norman pennies. (Referring to the old English term "steorling.")
Theory
II
Sterling silver was first known as "Easterling silver",
which was used in reference to the grade of silver originally used
as the local currency in an area of Germany, known as the "Easterling."
King Henry II set to adopt the alloy as the standard for English
currency. He imported metal refiners from the Easterling and put
them to work making silver coins for England. The silver these refiners
produced came into use as the currency by 1158 in the form of what
are known as Tealby Pennies. These Tealby Pennies were eventually
adopted as a standard alloy throughout England and the original
term "Easterling Silver" was abbreviated to "Sterling
Silver."
Most
silver coins today are 90% silver and 10% copper. This standard
was established in the 1820's.
Why
does Sterling Silver tarnish?
Sterling
silver tarnish build up is the dulling that naturally occurs when
sterling silver reacts with sulfer or hydrogen sulfide in the air.
Chemically, silver itself does not react with oxygen or water at
ordinary temperatures, so it does not easily form a silver oxide.
However, other metals in the alloy, usually copper, may react with
oxygen in the air.
How
can tarnish be prevented?
Sterling
silver tarnish can be prevented by storing your sterling silver
jewelry in air tight and tarnish-free containers. Air tight plastic
bags work well for keeping your sterling silver jewelry tarnish
free. You can also use tarnish free jewelry storage bags or jewelry
boxes. Wearing your sterling silver jewelry is another preventative
way to keep your jewelry tarnish free. If your sterling silver jewelry
is already tarnished, you can use a polish formulated specifically
to remove tarnish. Rinse with clear water and pat dry. Only use
a soft cloth when removing tarnish from your sterling silver, other
materials may scratch the soft metal. Do not use toothpaste or other
abbrasives to clean your sterling silver. Do not wear your sterling
silver jewelry in chlorinated water or expose it to household chemicals
such as bleach or ammonia.
To protect your jewelry from scratches and other damage, store your
jewelry away from other pieces in your jewelry box. This will prevent
jewelry from rubbing against your sterling silver, pearls or other
vulnerable elements.
Sterling
Silver vs. Silver Plated
Silver
plated is usually a sterling silver overlay or plate over a base,
non-precious metal. Since the sterling silver is layered over a
base metal, it cannot bear the 925 mark of sterling silver. Silver
plate has no intrinsic silver value.
Sterling
silver will last forever if you want to use it and care for it properly.
Silver plate will last about 20 years or less depending on the use
and the proper care.
What
is Vermeil?
Vermeil
is a 22kt gold plate or overlay over sterling silver. This is an
increased trend making gold more affordable while keeping the precious
metal value. It bridges the gap between gold fill, which is a base
metal rolled in gold, and solid gold, which is expensive and increasing
regularly. All three choices, gold fill, vermeil, and gold hold
more value than gold plate. Read more about gold fill.
What
metals does Kincaidesigns use in
their handmade jewelry?
Kincaidesigns
uses precious metals of sterling silver and gold fill. Gold-filled,
or gold overlay, is made by heat and pressure-bonding a thin layer
of gold to a brass core. The gold covers the brass surface, making
it tarnish resistant. The value of gold-fill is greater than gold-plated
because gold-fill has an actual layer of gold, not just a microscopic
film. All the 14kt gold-filled materials used by Kincaidesigns handmade
jewelry meets federal standards for quality and content.
