However, this group contains other materials that are much less well known, but more expensive. We offer you a list of the highest priced metals.

The most expensive metal in the world is rhodium. It is an extremely rare chemical element: one ton of the earth's crust contains only 0.001 grams of this metal.

Rhodium has a high melting point and is very resistant to corrosion. Thanks to its reflective properties, it is often used in mirrors, lamps and jewelry. In addition, it is a necessary material for automotive production and for other industrial fields.

Another high-priced noble metal is platinum. It is a dense, malleable, slightly reactive and non-corrosive material. It is used in jewelry, laboratory equipment, electrical contacts, fillings, and automobile catalysts.

The main producing countries of rhodium and platinum are South Africa, Russia and Canada.

Clearly, the most recognizable precious metal is gold. Due to its appearance, it is widely used in jewelry. At the same time, it is used in the construction of electronic devices, radiation shielding, and thermal insulation equipment.

Additionally, the yellow metal is a popular investment choice.

The countries that extract the most gold are South Africa, the USA, China, Australia and Russia.

The next most expensive metal is ruthenium, which is used in making electronic devices and high-resistance electrical contacts.

All metals mentioned —except gold— ​​belong to the platinum group, which includes six metallic elements with similar physical and chemical properties.

Iridium is often mined along with platinum or collected as a by-product of nickel production.

The largest producer of iridium is South Africa. The metal is used to make pens, watches, jewelry, compasses, electronic devices, automobiles, and medical instruments.
