Named by the 16th century Spanish conquistadors
in South America, platinum’s rarity, beauty, and physical
properties combined make it the most noble and precious metal
of all precious metals. In the mid 1700s the first samples
of platinum ore made its journey from South America to Europe,
however, it wasn’t used in the jewelry industry until
French jeweler, Cartier first created platinum jewelry in
the 1890s. Platinum soon became a symbol of status, luxury,
and elegance, growing in popularity through the Edwardian
era (1890-1915), during the 1920s and 1930s Art Deco era,
and continued despite the U.S. Depression. When World War
II began, platinum was declared as a strategic metal. Its
high resistance to corrosion made it a perfect metal choice
for the production of jet aircraft engines and platinum was
banned from jewelry manufacturing use, until after the war.
Many women engaged before WWII wore diamond engagement rings
set in platinum, however when they were married during the
war, platinum wasn’t available and they were given a
wedding band made to resemble platinum - white gold.
After the war, platinum continued to be seen as the choice
metal for showcasing large diamonds and important jewelry.
In the past decade the world has experienced a tremendous
appreciation and rise in popularity of platinum jewelry. Today,
platinum is used in all types of jewelry, at various prices.
Prized for its beauty, rarity, and purity, platinum used in
jewelry is 90-95% pure platinum alloyed with another platinum
group metal such as iridium, palladium, ruthenium, or rhodium.
In comparison, 14K (karat) gold is 58.5% pure, 18K gold is
75% pure, and sterling silver is 92.5% pure. Because platinum
is pure, it will not tarnish, react with chlorine or cause
allergic reactions.
Since first discovered in 1924, South Africa has been become
the world’s leading producer of platinum ore. Platinum
is rare and about 2.8 million ounces of platinum are mined
each year versus 50 million ounces of gold and 400 million
ounces of silver. Ten tons of ore is required to produce one
ounce of platinum. Extremely durable, resistant to corrosion,
and ductile (ability to be drawn into wire) are the characteristics
that make platinum a perfect metal for use in manufacturing
delicate and intricate jewelry designs. Because of platinum’s
hardness (jewelry prongs and settings are long-lasting) and
overall wear-ability, platinum is an ideal metal use in setting
diamonds, and showing off gemstones.
