Gold

Gold is the world's third most expensive precious metal. This precious metal needs no introduction because gold is the most well-known metal on the planet.

Gold is a bright yellow, dense, soft, malleable, and ductile metal that is one of the least reactive chemical elements on the planet in its purest form. In rocks, veins, and alluvial deposits, gold is frequently discovered in its free element natural form, as nuggets or grains.

It's still regarded as rare, which explains the high price, and has been used for coins, jewelry, and art throughout history. China continues to produce the most gold, with an estimated 440 tons per year. The price of gold per gram is around $53.95.
