Silver (Sterling)
History
Silver is one
of the first metals to be used by humans. It may have been the
first metal smelted from ore. The art of silver working dates
back to the ancient Byzantine, Phoenician and Egyptian empires,
where silver was forged into domestic utensils, jewellery, buttons,
weapons, horse trappings, boxes, and other articles.
Unfortunately,
silver's high utility meant that items were often melted down
and re-forged into new items. Consequently, much ancient and
early European silverwork has been lost forever. The silver
tradition was carried over to colonial America, where it co-existed
with the centuries-old hand-hammered craft traditions of the
North and South American natives.
The mines in Mexico and Peru are still the highest-producing
ones in the world, and the methods of silver jewellery making
among native peoples remains largely unchanged today. The
niche of silver making in Western society has been a bit more
dynamic. Silver's value as a jewelelry and utensil metal made
it an early target for ambitious miners, and the discovery
of the Comstock Lode in Nevada in 1859 created a silver rush
that rivaled the Gold Rush.
In
recent years, silver has lost much of its value as a reserve
metal and a traded commodity. However, its low price often
means it acts as a leading metal in jewelry fashion - allowing
silver craftsmen freedom to experiment with new and innovative
designs, which are later duplicated in more expensive gold
and platinum, once the "style" is safely established.
Silver
is popular among younger people attempting a less-formal look
in their accessorizing, and among those who simply find gold
and platinum too old-world and ostentatious.
Finish
Silver is also the brightest reflector of any metal (except
for liquid mercury) and can be polished to a high sheen that
even platinum can't achieve. In fact, the chemical symbol
for silver, Ag, is derived from the Latin, argentum, meaning
"white and shining."
The finish on silver can be high polished, matte or brushed
(rubbed with an abrasive), satin (a smoother matte), sandblasted
(rough matte), oxidized (chemically blackened), or antiqued
(chemically "aged"). Silver is said to have a "patina,"
a worn-looking finish that is achieved through frequent use
and handling, and is particular to the wearer's skin chemistry.
Purity
In its
pure form silver is almost as soft as gold, and therefore
is usually alloyed with copper for strength. Karatage is not
marked because, legally, anything called "silver"
or "sterling silver" is 92.5% pure.
Sometimes
silver from south of the border is designated "Mexican
silver," which runs anywhere from 90% to 99% pure. Purity
is really not something to worry about with silver.
Alloys
Fine Silver
in its natural state, 999/1000 pure, is too soft an element
for practical jewelry. To make it workable, an alloy such
as copper is added. Here are the main silver alloys:
Sterling
Silver: A mixture of 92.5 % pure silver (925 parts)
and 7.5 % metal alloy.
Silver
Plating: Also known as silver plated or silver coated.
A base metal, usually nickel silver or brass, is coated with
a layer of pure silver by a process called electroplating.
Vermeil:
Sterling silver electroplated with at least 100 millionths
of an inch of karat gold
German
Silver or Nickel Silver: A silver-white alloy consisting
of copper, zinc and nickel.
Coin
Silver: 90% (900 parts) pure silver and 10% (100
parts) metal alloy. A process of melting down coins done in
the 19th century, and mostly discarded today.
