What is Platinum?
Platinum is a silver metal and it is one of the most precious metals just like gold and silver. Most of the platinum produced in the world comes from South Africa. It is more precious than gold and rarer than it. You rarely find a piece of jewelry made entirely of pure platinum because it is often mixed with some other metals such as copper, palladium or cobalt. The higher the purity of platinum jewelry is, the higher its price will be.
