What does platinum mean?

Platinum is a natural pure white precious metal and is known as the king of precious metals.

From prehistoric civilization to princess and platinum, the protagonist of pop music, the so-called "new metal", its story is far longer than you think. Meteorites contain platinum, and the earliest record can be traced back to 2 billion years ago, when a meteor hit the earth. Since then, this rare and fascinating treasure has appeared sporadically throughout history, and sometimes suddenly disappeared for centuries, which is both confusing and attracting people who meet unexpectedly.

The ancient Egyptians, the ancient Inca civilization and the Spanish conquerors all encountered platinum. Later, it reappeared in the18th century, which made kings and alchemists equally crazy. 19 and the 20th century, platinum was more and more admired and loved by people. Today, it has become the precious metal of choice for movie stars and elites.
