Platinum
Platinum is a white metal, but unlike
gold it is used in jewellery in almost its
pure form
(approximately 95% pure)
Platinum is extremely long wearing and
is very white, so it does not need to be
Rhodium plated like white gold.
Platinum is very dense (heavy), so a
Platinum ring will feel much heavier than an
18Kt gold ring.
Platinum is, however, very expensive. A
Platinum ring will be approximately
two to three times the the price of an 18Kt white gold
ring (excluding gemstone costs).

The History of Platinum
Although Platinum may seem new, it is
also legendary. The ancient Egyptians
and South American Incas prized it. France's Louis XVI proclaimed it the
only metal fit for royalty.
Legendary jewelers such as Cartier,
Faberge and Tiffany created their
timeless designs in Platinum. The
world's famous diamonds, including the
Hope, Jonker I and Koh-I-Noor, are
secured by the permanence of Platinum.
Platinum reached its peak of popularity
in the early 1900's when it was the
preferred metal for all fine jewellery. When World War II began, the
U.S. government declared Platinum a
strategic metal and its use in
non-military applications, including jewellery, was disallowed. To appease
consumers who preferred Platinum's white
lustre and to provide a more affordable
alternative,
white gold
was developed.
What is Platinum?
Beneath its subtle
beauty and understated elegance lie the
properties which make Platinum truly
unique.
Platinum
is strong
It is the heaviest of the precious
metals, weighing almost twice as much as
karat gold. Its strength ideally secures
diamonds and other precious gems. Even
after many years, Platinum will not wear
away or wear down.
Platinum is pure
In America, Platinum jewellery contains
either 90% or 95% pure Platinum. By
comparison, 18K gold is 75% pure and 14
karat is 57% pure gold. Only
Platinum
will never tarnish or lose its rich
white luster. Because Platinum is so
pure, it is hypoallergenic.
Platinum is rare
Ten tons of ore must be mined to produce
a single ounce of Platinum. It takes
five months to process Platinum ore into
pure Platinum. Only after this time can
skilled hands work their creativity and
craftsmanship, transforming Platinum
into pieces of wearable art.
How to Buy and Care for Platinum jewellery
Platinum jewellery made in North America
contains either 90% or 95% pure
Platinum. Platinum jewellery marked "IRIDPLAT"
contains 90% Platinum and 10% iridium. When marked "PLAT" an item is at least
95% Platinum, with 5% ruthenium.
Platinum jewellery should be cleaned the
same way you clean other fine jewellery.
Use a pre-packaged jewellery cleaner or
have it professionally cleaned by your
jeweler. As with all precious jewellery,
store with care, not allowing pieces to
touch or scratch each other.
