Introduction to Gold and Platinum
Without gold, it is said, there would be no jewelry. For thousands of years,
men have fought, sailed oceans, braved jungles and moved mountains for gold.
Every great civilization has left a legacy of gold jewelry that unfailingly
dazzles the modern eye.
Too soft for tools or weapons, gold was thought to be the metal of the sun,
coveted for its natural beauty and worshiped for its mystical powers. Today,
gold is cherished not just as a rare precious metal. Its physical properties
are unrivaled for creating fine jewelry.
Stretch an ounce of gold into 50 miles of fine wire. Hammer an ounce into a
square, 100 feet wide. It resists tarnish and rust. It is immune to corrosion,
oxidation and acids. Gold's value comes from both its beauty and scarcity.
All of the gold mined in the past 6,000 years would fit into a cube 60 feet tall.
What are Karats?
Karats are a measure of the percentage of gold to alloy contained in gold jewelry.
Gold is mixed with alloy for strength. Metal stamped 24K, meaning 24-karat gold,
is considered pure gold and too soft be used for jewelry. More common 18K gold
contains 75% pure gold. Jewelry marked 14K appears the most widely. Anything under
10K cannot be labeled or sold as gold.
Yellow gold, capturing the metal's classic natural color, is by far the favorite.
Copper and silver are the alloys used most with yellow gold. For the
fashion-conscious, white gold is hot and trendy.
The value of gold jewelry is based on several factors: fineness or karat count,
weight in grams and the workmanship reflected in the piece.
Platinum The Royal Metal
From ancient Egypt to pre-Columbian South America, platinum plays a leading role
in the creation of exquisitely fine jewelry. Not until the 18th century did it
begin to appear in the jewelry of Western Europe. It soon became the metal of
royalty.
Platinum ranks among the rarest of metals. Ten tons of ore yield one ounce of
platinum. For every 15 to 20 ounces of gold extracted, only a single ounce of
palladium is mined. Mountains of rock must be crushed to meet world demand and
the refining process takes nearly a half-year. Unlike gold, which doesn't work
well in its purest form, platinum is used in jewelry at 90-95% purity. Platinum
of this fineness is stamped 900Pt, 950 Plat or just Plat. Even in this pure state,
platinum contains five other metals -- iridium, osmium, palladium, rhodium and
ruthenium. Like gold, it is tarnish and rust resistant.
Safekeeping Gold and Platinum Jewelry
Many of us treasure the gold and platinum jewelry pieces that have become family
heirlooms. Proper care protected the jewelry as it passed from generation to
generation. When you purchase gold or platinum jewelry from ICE, we hope you will
follow a few simple rules for its care and safekeeping. Avoid harsh chemicals or
abrasives. Don't wear rings, bracelets and other jewelry while working with power
tools. Store each piece separately in a soft cloth pouch or in the separate
compartments of a jewelry case. Check that gem settings are secure. If not, ask
a professional jeweler to re-set them.
