History of Platinum
Platinum, like gold, has a long and distinguished history. Its use began in
antiquity and it has undergone a resurgence in popularity over the last 200
years. Platinum was held in high esteem during early Egyptian times. Native
people in South and Central America worked it as early as 100 B.C.
Spanish conquistadors discovered platinum artifacts among the
gold they were seeking when they came to the new world. They named the curious
metal "platina," or "little silver." They also considered it worthless, and
discarded it. Platinum didn't reach Europe until the 18th century. It was
highly regarded as King Louis XVI called it "the metal of kings."
For centuries, the only large amounts of platinum outside of
South America were found in Russian mines. Nowadays, platinum is far more
valuable than gold. Platinum's initial uses were probably limited by its
hardness and its very high melting point. The early forging and casting
techniques made it quite a difficult metal with which to work and mold.
During the latter part of the 19th century, and the first half
of the 20th, platinum was the premier metal for all-important jewelry. Platinum
dominated the world of jewelry design during the Edwardian era and the Art Deco
period well. This dominance prevailed into the 1930s. With World War II came
the abrupt end of platinum jewelry as platinum was declared a strategic metal
and all non-military uses of the metal was banned.
Beauty of Platinum
The appeal of platinum is in its appearance. Its white luster is
unique. It is also the strongest precious metal used in jewelry, and is almost
twice as heavy as 14-karat gold. This weight is one of platinum's strongest
selling points, because it gives "heft" to fine jewelry, which people naturally
equate with value.
In recent years platinum has rapidly grown in popularity. It has
become the new choice for many diamond engagement rings because its luster
brings out the brilliance of diamonds far better than gold.
Many fashion consultants agree that platinum (and white gold) is
more compatible with fairer skin tones. The Japanese seem to be listening --
almost 85% of platinum jewelry produced every year is purchased by Japanese
consumers
Origin of Platinum
Go To Top 
Despite its growing popularity, platinum remains one of the
world's rare metals. The annual worldwide production of platinum amounts to
some 160 tons, compared to about 1,500 tons of gold. It can be found in just a
handful of regions of the world. The mining and refining processes are both
arduous and time-consuming. For example, in order to extract a single ounce of
platinum, about 10 tons of ore need to be mined. After that, the refining
process takes a full five months.
Platinum in jewelry is actually an alloyed group of six heavy
metals, including platinum, palladium, rhodium, ruthenium, iridium and osmium.
These other metals are so similar to platinum in weight and chemistry that most
were not even distinguished from each other until early in the nineteenth
century.
Today, it is often alloyed with copper and titanium. It's the
only precious metal used in fine jewelry that is 90% to 95% pure, largely
hypoallergenic, and tarnish-resistant. Look for platinum jewelry marked 900Pt,
950 Plat, or Plat.
Platinum Care
One final word about precious metals: Like gold, platinum is
durable, sturdy and dependable, making it an ideal setting for your precious
diamond jewelry. However, to get a lifetime of enjoyment from your jewelry, be
sure to keep it clean and safe.
Do not wear platinum jewelry during rough work or when handling
harsh chemicals.
Store it in a fabric-lined box away from other pieces so it does
not get scratched.
Finally, check any diamond settings periodically for possible
damage to prongs or bezels. If you see a loose prong, or if the setting looks
out of line, immediately bring it to a professional for repair.
