Ask most people which metal commands the highest price and gold quickly comes to mind. Today gold trades at roughly 1,800 euros per 31.1 grams, underscoring its status as a premier precious metal. Yet gold is not the most valuable metal on the planet. That distinction belongs to rhodium, a rarer element with an eye watering price tag.
Rhodium presently sits at the pinnacle of precious metals in both price and scarcity. An ounce trades around 4,100 dollars, and there have been moments when the metal surged dramatically. A notable spike occurred in December 2022 when it briefly touched about 14,000 dollars per ounce. Even with fluctuations, rhodium outpaces gold by a wide margin, securing its position as the priciest metal in the market today.
What drives rhodium’s high cost It resists oxidation and corrosion, earning it the classification of a noble metal. It also serves as an exceptional catalyst and boasts a melting point near 1,964 degrees Celsius. This combination places rhodium among the platinum group metals, alongside platinum, palladium, osmium, iridium, and ruthenium, all valued for high temperature performance and durability.
Rhodium’s defining strength lies in its resilience to water and air at temperatures up to 600 degrees while remaining largely insoluble in most acids. Those properties support a broad array of industrial uses, from automotive catalytic systems to aerospace components and high temperature electrical contacts. The metal also finds roles in specialized thermocouples and robust cables, and it is frequently alloyed with other platinum group metals to enhance performance in demanding environments.
Despite its rarity, rhodium remains in high demand. Industry data from recent years show that a large portion of consumption flows into jewelry, while catalytic converters represent a substantial share of automotive demand. This mix mirrors the metal’s appeal for both decorative use and high specificity in technical applications.

A Very Rare Metal in the World
Rhodium is extraordinarily scarce, with estimates around 0.000037 parts per million in Earth’s crust. By comparison, gold appears at about 0.0013 parts per million. These figures illustrate why rhodium sits at such extreme rarity among metals. [Source: Royal Society of Chemistry data]
Primary deposits concentrate in South Africa and Russia. Rhodium also occurs as a byproduct of refining copper and nickel ores, where it can appear in trace to small percentages. Global annual production hovers near 16 tons, and reserves are estimated in the low thousands of tons, ensuring that supply remains tight for the foreseeable future.

The metal is often found alongside platinum deposits and traces its discovery to the British chemist William Hyde Wollaston in 1803. Wollaston extracted rhodium from a platinum sample found in South America, continuing his work in the same line that led to the identification of palladium.

Rhodium is typically separated from platinum and palladium to reveal a bright silvery white solid. Its name derives from the Greek word rhodon meaning rose, a nod to the pinkish tint of rhodium salts. The unique color and performance characteristics have long made rhodium a prized material in specialized applications. [Source: etymology and mineralogy references]
