The first writings describing Platinum were in 1557 by Italian Julius Caesar Scaliger (not 1735 as listed in many places online). The new metal was further observed during an expedition of New Grenada (now known as Colombia) by Antonio de Ulloa and Don Jorge Juan y Santacilia in 1735. Their writings related to this expedition refer to the new metal as Platinum.

What are facts about platinum?
Platinum is very hotPlatinum is platinumPlatinum is definitely one of the rarest and most sought after precious metals. Most people do not realize how rare platinum is. All of the platinum ever mined would fit in the average living room. There is only about 133 tons of platinum mined every year compared to approximately 1,782 tons of gold. It takes 10 tons of ore and a five-month process to make 1 ounce of platinum. Some people believe that platinum is a somewhat newer metal, however, it is legendary. The ancient Egyptians and South American Inca's thought it was priceless. Louis XVI of France made a proclamation that it was the only medal fit for royalty. The Spanish considered platinum a nuisance and named it platina, which means small silver. Platinum was the same color as silver but it resisted melting or forging so the Spanish government banned it from being imported in the 17th century. The little bit of platinum that did make it to Europe entered as contraband. In the 18th century platinum had captured the interest of the scientific community. They first thought it was an alloy of gold and iron and in 1751 they concluded it was in fact, a new metal. By the end of the 18th century because of platinum's properties and resistance to heat and acids made it popular for scientific, medical and industrial purposes. Some of the most renowned jewelers including Cartier, Faberge and Tiffany have created most of their timeless designs in platinum. The world-famous diamonds including the Hope, Jonker I, and the Koh-I-Noor are secured in platinum. In the early 1900's platinum reached its peak in popularity and was the preferred metal for all types of fine jewelry in America. This all changed when World War II began; because the US government declared platinum a strategic metal and any non-military application of this medal including jewelry was disallowed. To try to satisfy consumers who prefer platinum's white luster, white gold was substituted in platinum's absence. Today, once again, platinum charms a new generation of consumers; it is very fashionable to wear platinum and gold jewelry together. In fact many jewelry designs combine platinum and gold together. The white color of platinum contrasts beautifully with yellow gold and adds versatility to jewelry. Platinum is the heaviest of precious metals and weighs almost twice as much as a karat of gold. It is very strong and will secure diamonds and other precious gems in their settings. Unlike gold, after many years platinum will not wear away or wear down. As with any and all precious metals including gold and silver, platinum can be scratched. However, platinum doesn't scratch the same as gold and you can take a platinum piece of scratched jewelry and all the jeweler has to do is polish it and it will be as good as new. Platinum jewelry is one of the purest medals and most American jewelry contains 90% to 95% of pure platinum. On the other hand, 18 karat gold is only 75% pure and 14 karat gold is 58% pure gold. Another advantage to platinum is that it will never tarnish or lose its rich white luster. Any type of jewelry set in platinum will be a rare classic and timeless piece. Platinum is one of earth's rarest gifts. A platinum piece of jewelry is a treasure to be worn for a lifetime.platinum is costlier than gold, it has got no resale value. it is very attractive.Well I know that it is the most expensive and rare precious metalPlatinum is the spanish root meaning "little silver" (monsteeeeeeeeeeer in spanish guess what it means)by aim
Facts about platinum?
Platinum is a metallic element with the chemical symbol Pt and an atomic number of 78. Its name is derived from the Spanish term platina del Pinto, which is literally translated into "little silver of the Pinto River." It is a dense, malleable, ductile, precious, gray-white transition metal. Platinum is one of the rarest elements in the Earth's crust and has an average abundance of approximately 0.005 mg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Some counterfeiters in the late 1500's made coins in South America from platinum that resembled silver coins (at the time platinum was unknown and not valued) The authorities confiscated the coins, set them on a ship out to sea in the Pacific and scuttled the ship. It sank in an unknown location. Today that trove of platinum would be very valuable.
