Platinum 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, but then it caught on in a big way. King Louis XVI elevated it by terming 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 to work with. During the latter part of the 19th century, and the first half of the 20th, platinum was the premier metal for all-important jewellery. Platinum dominated the world of jewellery design during the Edwardian era, and the Art Deco period well into the 1930s. It all came to an abrupt end in World War II, when platinum was declared a strategic metal and its use banned for all non-military purposes. Origins 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. Care 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 claws or bezels. If you see a loose claw, or if the setting looks out of line, immediately bring it to a professional for repair.
