14. Rhodium – $58 per gram
Nearly 60% of all rhodium is found in South Africa. A silver-white material that’s a member of the platinum group of metals, this element is less dense and more resistant to heat than platinum while featuring excellent durability, hardness and reflectance.As a result, this element, sometimes referred to as “white gold”, can be found in jewelry, aircraft engines, search lights and processes that manufacture acids and organics. Part of the reason rhodium has a high price is due to interruptions in Russian supplies during the late 90s.
