In 1940 the U.S. Government declared Platinum illegal to use in jewelry, which was lifted after the second World War.
Platinum is one of the rarest of all precious metals, found only in a few locations in the world.
To produce a single ounce of platinum, a massive 10 tons of ore must be mined. For many years Japan was the largest market for Platinum but North America is catching up fast. Europe is next. Platinum cost more because it is much more pure than gold and it is heavier. Platinum is more dense than gold which means it wears better than gold.
