Precious metals
A precious metal is a rare natural metallic chemical element with high economic value such as gold, silver, platinum, rhodium, and palladium. The concept of precious metal varies depending on the era, civilizations, as well as supply and demand. A metal is considered precious if it is rare.
The best-known precious metals are those used for coins, gold and silver. Although both have industrial uses, they are better known for their applications in art, jewelry, and fine jewelry.
Furthermore, semi-precious metals are also mentioned for less sought-after but rare elements like copper.
