Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of ...

Precious metals, particularly the noble metals, are more corrosion resistant and less chemically reactive than most elements. They are usually ductile and have a high lustre. Historically, precious metals were important as currency but they are now regarded mainly as investment and industrial raw materials.
The overall concentration of iridium on Earth is thought to be much higher than what is observed in crustal rocks, but because of the density and siderophilic ("iron-loving") character of iridium, it descended below the crust and into Earth's core when the planet was still molten.

Rhodium has the highest price of these precious metals ($440,000/kg in 2022 [3]), but the cost of the separation of the rhodium from the other metals needs to be considered [editorializing], although recent high prices may create opportunity for consideration. [1]
With the current inflation rate, things that cost a dollar 50 years ago would approximate cost $7.03 today. Not everything was cheaper in 1972, but most things were even when adjusted for inflation.
