Platinum occurs naturally, albeit in small quantities, in the Earth's crust at about 0.000037 parts per million. One of the rarest precious metals, the world's supply of platinum is obtained as a byproduct of nickel and copper mining and production, because platinum occurs in nickel and copper ores. Pure platinum that is found in placer deposits and other ores, on the other hand, is extracted using a variety of methods.Know More
Its rarity and very high resistance to corrosion makes platinum a prized base precious metal for jewelry. While it has often been mistaken for silver in the past, it does not tarnish and just like gold, it does not wear out.
