While rhodium is often the most expensive precious metal by mass due to its extreme rarity and use in catalytic converters, man-made Californium is vastly more valuable, and naturally occurring Iridium and Francium, along with high-quality Diamonds, can also exceed its price, depending on market conditions and form.
The current price of Rhodium is $342.49 per gram.

Palladium is the most expensive of the four major precious metals – gold, silver and platinum being the others. It is rarer than platinum, and is used in larger quantities for catalytic converters.
The 10 Most Expensive Minerals in the World
Introducing… Magnesium! Otherwise known as The King of Minerals. Now, not any nutrient can get this grandiose title.
The Crown Jewel of Rare Metals: Rhodium
This shiny, silver-white metal is part of the platinum group, but it's about 10 times rarer than platinum itself. In fact, it's so rare that annual worldwide production is only around 30 tons—compare that to gold's 3,000 tons, and you'll see why rhodium is the ultimate flex.
If you ask what the most valuable precious metal is, rhodium takes the crown in terms of price per ounce. However, for long-term stability, gold and silver remain popular for investors.
Noble metals refer to ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), osmium (Os), iridium (Ir), platinum (Pt), and gold (Ag).
Rhodium is the rarest of all non-radioactive metals. It occurs uncombined in nature, along with other platinum metals, in river sands in North and South America. It is also found in the copper-nickel sulfide ores of Ontario, Canada. Rhodium is obtained commercially as a by-product of copper and nickel refining.
Market Supply and Demand: If the supply of PGMs exceeds demand, prices fall. This can happen due to increased mining output, reduced industrial demand, or advancements in technology that reduce the amount of PGMs needed for applications like catalytic converters.
Typically, the amount of rhodium in a catalytic converter is anywhere between 1-2 grams, while the amount of platinum ranges anywhere from 3 to 7 grams and the amount of palladium ranges anywhere from 2 to 7 grams.
As of early January 2026, the price of palladium per gram fluctuates but hovers around $58 to $60 USD, depending on the market source, with slight variations for different currencies like €52.54 or A$89.49. It's important to check live metal pricing sites, as these figures are based on recent spot prices for 24k (99.9%) pure palladium.
Although the underlying metal may be magnetic, the rhodium plating itself is not magnetic. Thus, if you have a piece of jewelry that has been rhodium plated, it will not be magnetic.
Platinum is one of the rarest metals, occurring at very low concentrations in the Earth's crust. It is 30 times rarer than gold.
Black metal is produced by applying various processes to base metals such as iron, aluminum, stainless steel, and titanium. The most popular black metal material is black iron sheet with black skin. This material is widely sold and distributed because the oxide film of iron has turned black.
Gold nugget A selection of precious metal elements: copper, ruthenium, rhodium, palladium, silver, rhenium, osmium, iridium, platinum, gold and mercury. They are labeled and arranged by their location on the periodic table. The best known precious metals are the precious coinage metals, which are gold and silver.
If you invested $1,000 in gold 10 years ago (around late 2015/early 2016), your investment would likely be worth significantly more today (late 2025), potentially in the range of $2,000 to over $3,000, reflecting substantial price appreciation, though less than the S&P 500 but outperforming during certain periods of market stress, acting as a hedge against uncertainty, with returns varying based on exact entry/exit points and premiums/spreads.
Warren Buffett calls gold an "unproductive" asset
That's part of the reason he dislikes gold. In his 2011 letter to Berkshire's shareholders, he explicitly referred to it as an unproductive asset and highlighted two of its main shortcomings: Gold isn't very useful.
The price of silver is widely expected to increase in 2026, according to precious metals investing experts. And, as silver continues to sit near or break recent price records, investors may see it as a cheaper alternative to gold, and they may be right.
Australia holds at least four per cent of the world's rare earth element reserves, positioning it well for market growth. The Australian Critical Minerals Research and Development Hub aims to enhance understanding and processing of lower grade REE deposits.

Iridium extraction occurs as a byproduct of mining other metals. Iridium has several industrial applications, such as the aircraft industry. Its price has surged in recent times due to increased demand from the tech industry. Iridium is one of the rarest elements in the earth's crust.
