What is "platinum"?
Platinum is a lustrous, silver-white metal with excellent resistance to corrosion and high melting point. It is a precious metal and is one of the rarest elements found in the Earth's crust. Due to its durability, ductility, and non-reactivity with other elements, platinum is widely used in jewelry making, particularly for engagement and wedding rings. Platinum is also used in a variety of other applications, including in electronics, automobiles, and medical equipment. Due to its rarity and high demand, platinum is often more expensive than gold.
