Pure lutetium metal is very difficult to prepare. It is one of the rarest and most expensive of the rare earth metals with the price about US$10,000 per kilogram, or about one-fourth that of gold. [41] [42] Crushed minerals are treated with hot concentrated sulfuric acid to produce water-soluble sulfates of rare earths.
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 ...
Although aluminium is the third most abundant element and the most abundant metal in the Earth's crust, it was at first found to be exceedingly difficult to extract the metal from its various non-metallic ores. The great expense of refining the metal made the small available quantity of pure aluminium more valuable than gold. [16]

18. Platinum. Cost: $33.02 per gram Platinum is a beautiful precious metal that is in a similar category as gold and silver. All three of these metals are frequently traded in the global markets ...
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
Over the past 20 years, China has come to control 80 percent of the world's supply of rare earth metals and has repeatedly reminded global industrial powers of their market power. The post Rare ...
