Prices of chemical elements
Open-knowledge reference entry
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
As of 2025, the most expensive non-synthetic element by mass is rhodium, and by volume, iridium. It is followed by rhodium, 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 some synthetic radioisotopes range to trillions of dollars. While the difficulty of obtaining macroscopic samples of synthetic elements in part explains their high value, there has been interest in converting base metals to gold (chrysopoeia) since ancient times, but only deeper understanding of nuclear physics has allowed the actual production of a tiny amount of gold from other elements for research purposes as demonstrated by Glenn Seaborg. However, both this and other routes of synthesis of precious metals via nuclear reactions is orders of magnitude removed from economic viability.
Chlorine, sulfur and carbon (as coal) are cheapest by mass.
The public source identifies “Prices of chemical elements” as open-knowledge reference entry. This brief keeps that definition visible, then builds a research path around Prices, chemical and elements.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Prices of chemical elements”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 30, 2026. The linked authority identifier is Q7242660. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
